Adjusting plastic windows after replacing the seal. How to adjust plastic windows with your own hands

The main feature of opening windows is that they do not have vents. For better ventilation of the room, the system provides rotary doors. During the operation of plastic double-glazed windows, you may notice that a draft appears in winter. Don't panic - this is not a manufacturing defect, but simply the seasonal mode is set incorrectly. Switching plastic windows to winter and summer modes is a mandatory maintenance procedure.

The tilt and turn mechanism of the glass unit must be adjusted depending on the season of the year

During long-term use, drafts may also appear. This occurs due to the loosening of the hinge screws of the rotary-locking mechanisms. By independently adjusting the windows for the winter, you can easily save 3-7 thousand rubles on calling specialists.

Leak test

How to prepare plastic windows for winter? With the onset of cold weather, it is necessary to carry out a preventive inspection of the state of normal locking of the sashes in winter mode. Leak tightness can be checked in several ways:

• Tactile. By running your hand along the frame, you can determine the presence of serious drafts.
• Fire with a match or lighter. Deviation of the flame from the vertical indicates the presence of blowing.
• A sheet of paper. They leave him in the closed door and try to pull him out. If the leaf comes out easily, the sash does not close tightly.

If the paper sheet is easy to pull out through the sash, then the window is not airtight

Having identified problem areas, we begin to regulate the system to optimal requirements.

Blowing

To eliminate drafts, you need to adjust the mechanism of plastic windows.

At the end of the window there are eccentrics, with the help of which the fit of the sash is adjusted.

By turning the hexagon to the left, the fit is tightened, and in the opposite direction, it is loosened.

It is important that the fit is uniform and tight, for which the eccentrics are set equally.

When adjusting the pressure of a plastic window is done for the first time, an easy adjustment is made. The fact is that the rubber bands of the seal tend to shrink and deteriorate. If you press the sash hard during the first adjustment, the rubber bands will dry out faster, and subsequently you will have to change the seal.

In some mechanisms, the sash is pressed using plates. An extended tongue in the clamping mechanism means that the sash is firmly attached to the frame. On hinges located on the left side of the window, for a tight fit, the hexagon turns to the left side, and to the right - if the hinges are located on the right side.

Adjusting sash clamps in plastic windows

• 1 Adjusting sash clamps in plastic windows
• 2 Adjust the plastic window from blowing
• 3 Adjusting plastic windows: adjusting the lower hinges

From practice, we can conclude that the shapes of the locking protrusions can vary significantly. For routine adjustment of plastic windows, various types of tools are used. If you have oval-shaped windows, their position is changed using pliers: they should be clamped and turned to the side.

If the lug of the locking device is round, as shown in the left image, it is quite possible to make a slot in it for a hexagon. After a detailed inspection of them, you will be able to understand what tools you need: a standard screwdriver or a 4-point hex.

The eccentric is rotated using pliers or a hexagon

When systematically adjusting the window fittings, do not forget that a weak clamping mechanism corresponds to the warm season, while a standard or reinforced one corresponds to the winter season. If preventive work is carried out in the winter, first you need to move the window structure to the standard position and check whether there is any ventilation. At the same time, analyze the condition of the rubber bands on PVC windows. In winter, the rubber seal installed around the perimeter is pressed and, moreover, tightly. Over time, tension can cause elasticity to deteriorate. The factory warranty for the optimal type of seal is 15 years. But, despite this, if you set the pressure to maximum, the rubber will wear out much faster. Conclusion from the above information: the position of PVC windows for the winter-summer periods is set by adjusting the position of the locking pins.

Vertical and horizontal calibration is fast and efficient

First, let's look at how to adjust a window product vertically. Everything here is elementary. Find the location of the hinged bottom hinge, open the plug under which it is hidden. Insert the hexagon into the special hole and begin to carefully rotate it clockwise. This will cause the sash to rise. If you rotate the tool in the opposite direction, the sash will lower. Windows are calibrated horizontally in the same way. This setup allows you to solve various problems with plastic structures.

Plastic window calibration

If you need to fix a slight bevel of a window or a shift in its frame, you will need to remove the cover from the bottom hinge and use a furniture key according to the scheme already described above. Horizontal calibration makes it possible to adjust the window from both the inside and outside. In other words, you can easily adjust the window structure in a closed or open state. In practice, everything looks like this. Insert the hexagon and turn it.

When rotating counterclockwise, the lower section of the window structure will begin to lower. If you turn the adjusting key in the opposite direction, the bottom of the window will begin to rise.

Horizontal adjustments can also be made on the upper hinge of the structure. This need arises if a plastic window does not close well. Here you need to know one nuance. Such calibration is carried out only when the window is open. The principle of setting remains unchanged. Let us add that the shift of the sashes with the described repair methods is carried out by no more than 2 mm.

Types of adjustments

Adjustment of plastic window mechanisms is divided into two types, first, this is the regulation of the tightness of the valves. This type of adjustment is used when the seasons change. Namely, in winter, when the penetration of cold air from the street is undesirable, the window should fit as tightly as possible, and in summer the fit should be minimized, thus ensuring better ventilation of the rooms.

Winter-summer adjustment is a must, as it increases the service life of the window seals. With a minimal fit, the operating load on the seal is reduced, as a result, it straightens out, and the windows will fit better in the winter.

Second
It is impossible to make adjustments only by changing the position of one element of the fittings, as this leads to an increase in load and increased wear of all elements of the window. The adjustment must be carried out comprehensively to ensure that all elements of the fittings are evenly distributed.

1. After adjustment, you need to check how the window opens and closes Both in summer and winter you need to monitor the position of the valves. In warm weather it should be lowered a little. In winter, the sash is pressed tightly against the window. This is done in order to avoid freezing of the window and the appearance of drafts.
2. After adjustment, you need to check how the window opens and closes. So that there are no gaps, and the level of pressure is the same.
3. It is necessary to periodically check all elements of the fittings. They can wear out and become loose.
4. It is necessary to periodically lubricate all fittings.
5. The fasteners need to be tightened periodically.
6. If the adjustment is done correctly, then the window will open and close without extraneous sounds.
7. The screws that are responsible for the vertical position of the sashes They should all be in the same position.
8. When the window is open, then the seals must be of the same shape.
9. You can check the tightness of the valves using a sheet of paper. It must be inserted between the sash and the frame. When the shutters are closed, the paper cannot be reached.
10. If the adjustment is made incorrectly, this can lead to damage to the window mechanism. It is possible to accidentally break the adjustment bolts. The seal may become deformed.
11. If you are not sure that you can correctly adjust the mode yourself, it is better to entrust this work to specialists.
12. If deformations are found in the window frame or opening, then you won’t be able to fix this problem yourself. You'll have to call specialists.
13. Before adjusting the window, you need to remove the decorative plugs. This must be done carefully so that they are deformed.

It is necessary to adjust the window mode depending on the time of year very carefully. This work must be approached seriously and responsibly, because a person who is not experienced in this matter can break the window fittings and will have to call specialists and pay for repairs.

Regulation algorithm

Let's look at how to adjust plastic windows for the winter, effectively and correctly. The procedure itself is quite simple, requiring no special knowledge or tools:

• The most common adjustment option is to eliminate frame sagging. As the window sashes sag, it gets stuck or rubs against the frame.
• The fittings become loose over time. This malfunction must also be quickly corrected in order to avoid deformation of the window and increase its service life.

Let's consider each of the above options separately.

Sagging of sashes

This phenomenon occurs when the hinges (one or more) that hold the sash in place weaken over time. Subsequently, the lower corner of the sash gets stuck, and the structure quickly loses its properties and fails.

How to adjust plastic windows for the winter?

• Remove the protective caps from the loose hinge and tighten the largest bolt responsible for attracting the window sash.

Important! If the sash rubs from above, then you need to tighten the lower hinge while loosening the upper one. If the glass unit sag too much, it must be lifted slightly while tightening

• If the window sash needs to be moved slightly to the side, adjust the screws that are located vertically on the hinges. Depending on the direction of rotation, there is a shift to the right or left.

How to eliminate blowing?

To eliminate blows and drafts, adjust the force with which the window sash is pressed against the frame. You can change the downforce by acting on the trunnions located at the end of the window:

• Adjustment is made using a hexagon.
• The number of revolutions ranges from 2 to 6. As a rule, this is enough to create a normal microclimate in the room.

Important! You can check the uniformity of the pressure using a sheet of paper, pressing it between the sash and the frame. And checking the tightness of the window is carried out using a lit match or lighter, wrapping it around the perimeter of the window.

Loose fittings

Loose fittings that are not tightened in time are a direct threat to the entire window structure. The solution to this problem is quite simple: tighten the bolts. Preventative annual tightening of bolts contributes to greater strength of the window system.

Identifying areas that need adjustment

In order to determine the places that need to be adjusted, you first need to find out whether the sash pressure needs to be adjusted. To do this, you need to set the position of the trunnions, which are located near the handle, on the edge of the window. The pressure is determined using dots or small strips that are located on the circular section of the trunnions. If the stripes point to the top position, this means that the window clamp is currently in the middle or normal position. Usually this is the position that the specialist set for you when installing the window.

If you see that the stripes look inside the room, then this indicates that the design is currently set up for the winter season. And if the stripes look in the opposite direction, then, accordingly, for the summer season. In addition to the above, it would be useful to check the frame for sagging. Windows that were installed a long time ago are more likely to sag.

The sagging of the frame (sash) can be determined even by sound. When the sash sags, it rubs against the bottom of the frame, of course, this is accompanied by a specific sound.

How to adjust the hinges of plastic window sashes

In addition to seasonal adjustments to the degree of pressure, plastic windows are also adjusted by tightening/loosening the screws in the hinges that secure the sashes to the frame. There are two of them - one below, the second above. They differ in design, so they are pressed differently.

Options for plastic window mechanisms

Hinges on plastic windows have to be adjusted due to:

• initially poor, illiterate settings of the window unit during installation;
• natural wear of the seal;
• inaccurate and rough closing of the valves;
• window structure shrinkage;
• wear of parts of the tilt and turn mechanism.

As a result of all this, the sash sags and does not close tightly or does not close at all. However, to return it to its place, you just need to tighten the hinges. Moreover, you can perform such a pull-up on your own. There is no need to call the experts from the company that installed the window. All you need to do is have a screwdriver and a hex key on hand. This is not about repairing gasoline generators for the home, but with window structures everything is much simpler.

Plastic window adjustment points

Upper

The top hinge is adjusted from the side using a hexagon when the sash is fully open. After turning the screw there clockwise, the window leaf moves away from the frame, and when tightened counter-clockwise, it is pressed so that there is less of a barrel on top.

For more precise adjustment, there is also another bolt on the upper tilt and turn mechanism. But to get to it, you will have to press the blocker (set it strictly vertically) and turn the handle to the top ventilation (also in a vertical position). As a result, the sash on top should pull away from the frame, hanging on the lower hinge and opening full access to the upper one.

Adjusting the top hinge

It is important here not to over-tighten the adjustment bolts. There should be a small empty space between the sash and the frame, where, when closing the window, a tilt and turn device made of steel will be placed

Lower

The bottom hinge also has two adjustment screws. One of them is located on the side at the very bottom. He is responsible for horizontal adjustment - he presses the sash against the frame or pulls it away from it.

The second is located directly in the rotating mechanism itself. To get to it, you need to remove the plastic cap from the loop. This screw allows you to adjust the opening window leaf vertically (height). Turning it clockwise makes it go up, counter-clockwise means it goes down.

Bottom Hinge Adjustment

Manipulations when independently tightening the hinges on a plastic window should be done extremely carefully and without applying excessive force. Do not immediately tighten or unscrew the adjusting screw all the way.

It is better to turn it a quarter turn first and close the sash to check to see how smoothly it has become in the frame. And only then, if necessary, can the bolt be tightened further.

Eliminating sash sagging

This phenomenon manifests itself when one or more hinges holding the entire sash begin to weaken and give some vector deviation from the norm. Subsequently, the sash may get stuck at its lower corner, and when interacting with it, it touches the bottom, top or middle of the frame. Thus, the structure deteriorates very quickly and loses its properties.

To adjust plastic windows, it is necessary to remove the protective caps from the hinge we need and tighten the largest bolt, which is responsible for attracting the window sash. If friction occurs from above, you need to loosen the upper loop and tighten the lower one. When a double-glazed window sags too much, it must be slightly lifted while tightening.

If it is necessary to move the window door to one side, you should adjust the screws that are on the hinges in a vertical position. Depending on which direction the revolutions are made, the sash will move to the left or right.

Eliminating blowing

To eliminate drafts and various blows, it is necessary to adjust the clamping force of the plastic window sash. This is done very simply by acting on three trunnions, which are located on the end of the window.

They are adjusted using a hexagon by turning them around. To adjust, make from two to six revolutions; as a rule, this amount is quite enough to create comfortable conditions.

You can check whether this action is necessary using matches. Light one and carry it around the perimeter of the window, watching the flame. To check the uniformity of the pressure, you should use a piece of paper that is clamped between the sash and the frame while closing. This procedure is repeated along the entire perimeter of the PVC double-glazed window.

Loose fittings

If any elements of the fittings have lost the rigidity of their fastening, they should be tightened. Since such looseness is fraught with rapid failure of a separate section or the entire system at once. As a rule, all fittings are secured with bolts, which over time may lose their original rigidity.

This problem can be solved very simply by tightening the bolts more tightly. Experts advise carrying out such a twist once a year to eliminate minor faults and prevent the system.

Winter and summer mode

Plastic windows often need to be adjusted for the winter. It is in winter that complete sealing is necessary. In the summer you can let in some fresh air. This is achieved by adjusting the pressure density of the sash. Everything is done in an elementary way.

When adjusting the fittings, you should remember that the summer mode corresponds to a weak window closing pressure, and the winter mode corresponds to a strong or standard one. If work is carried out in winter, then first you should set the standard position and check whether there is airflow. On new PVC, you should not immediately pinch the rubber bands. In this position, the rubber seal installed around the perimeter is strongly pressed. Over time, this causes it to lose its elasticity.

If you immediately set the maximum pressure level, the rubber will deteriorate faster. As a result, the next time you set the plastic windows to the winter position, you will find the elastic all in cracks, and there will still be blowing from under the sash. This means that the seal needs to be replaced. This is not a very difficult process, but it will take more time.

Let's highlight the main requirements for PVC windows to last as long as possible at different times of the year:

• Do the adjustments yourself correctly so that you do not have to repair the plastic window.
• Insulation materials must be replaced promptly when worn out.
• In summer, loosen the pressure.
• In winter mode, the fittings should not be left for the whole year.

Reasons for decreased performance of double-glazed windows

Reason 1. Change of seasons

Adjustment of the pressure of the sash to the frame is carried out using a small mechanism - a pin. In addition, the locking pin allows you to increase the reliability and safety of the structure (it is much more difficult to break into it from the outside). The amount of air entering the room depends on the position of the trunnions.

First, let's find out what a trunnion is and what it looks like. Common options are presented in the table:

Image	Description
	Option 1. Standard shut-off. Can be adjusted using a hex wrench, slotted screwdriver or by hand. This is the most common type of trunnion.
	Option 2. Eccentric roller with a notch. Adjustable without the use of additional devices. You can change the mode yourself.
	Option 3. Anti-burglary. Can be adjusted using a 4mm hex wrench or a special trunnion wrench. The price of windows with installed anti-burglary fittings is significantly higher than their analogues.
	Option 4. Mushroom-shaped. You can change the position using a special key for such fittings. When installing windows you will be required to provide such a key.

The table describes how to change the window mode using the example of an eccentric roller with a notch:

Image	Instructions
	Mode 1. Summer: Open the window. Turn the window handles to the “Ventilation” position. To loosen the pressure, rotate the roller counterclockwise several times. The notch should be on the left.
	Mode 2. Autumn (spring): Repeat the first 2 steps from the previous method. Depending on the starting position, rotate the trunnion so that the notch faces up. Usually, when installing windows, the middle position is set.
	Mode 3. Winter. Adjusting plastic windows for winter is almost the same as for summer. The only difference: the trunnion must be turned clockwise. The notch should face to the right.

It is advisable to set the “plastic windows - winter” mode with the first frost. Such manipulations will better retain heat inside the room and reduce wear and tear on window fittings.

Reason 2. Problems with the performance of the sashes

Let's consider the main reasons for sagging sashes:

• Heavy weight. It is not recommended to keep large windows open for a long time. The doors lower under their own weight.
• Incorrect installation. It is possible that mistakes were made when installing the window sash.
• Improper use. Hanging anything on the windows to dry is highly undesirable. There is no need to intentionally add weight to an already cumbersome structure.

There should be no foreign objects hanging on the windows so as not to weigh down the structure and prevent the sash from sagging

Algorithm for how to independently restore the correct geometry of the valves:

Image	Description
	Stage 1. Remove glazing beads We insert a knife with an oval blade into the gap between the frame and the bead. We push the knife all the way and run it along the entire length of the bead. We take out the glazing beads (long ones first, then short ones).
	Stage 2. Remove the glass unit Prepare a substrate that will be used to level the frame under the double-glazed window. Hold the glass unit, make sure that it does not depressurize. Place the substrates on top of the glass unit and adjust to the required size.
	Stage 3. Hammering glazing beads Using a rubber hammer, return the short beads into place. Now you need to install the long ones. Finally, hammer around the entire perimeter one more time.

Reason 3. Friction of the valves

There may be situations when, during use, grinding, creaking and friction of the internal mechanisms of the windows are heard. This problem can be eliminated by adjusting the special screws located at the top hinge. To do this, you need to open the window 90° and insert the hex key into the screw (example in the photo below).

Screw in the upper adjustment mechanism.

By turning the screw you can:

• slightly tighten the mechanism to eliminate unpleasant sounds;
• raise the corner diagonally (rotate clockwise);
• lower the corner diagonally (rotate counterclockwise).

Check the effect after each revolution so as not to overload the mechanisms.

Maintenance of plastic window systems

As a rule, breakdowns of plastic windows are caused by improper use of window fittings and untimely adjustment. Small parts can create a lot of problems if not taken care of. Let's look at the basic rules that will help you prevent damage to plastic windows and fittings:

1. Wash your plastic windows thoroughly twice a year. Particular attention should be paid to the elements located at the top of the sash. It is in this place that dirt and dust accumulate, which can cause breakdowns.
2. In addition to cleaning, the mechanism must be thoroughly lubricated. Special means for adjustment and lubrication can be purchased at all construction supermarkets. When purchasing, pay attention to the composition: it should not contain resins or aggressive acids. The fittings are treated with a special anti-corrosion coating, so the detergent must be soft so as not to disturb it.
3. Maintenance and adjustments must be carried out regularly. Try to wash and lubricate your plastic blocks at least once a year.
4. When making scheduled adjustments, do not forget to check the attachment points of all parts. If necessary, replace or tighten the screws. Remember: the correct operation of plastic structures depends on the correct fastening of the fittings.
5. If the damage is so serious that you cannot adjust the plastic windows yourself, contact customer service immediately.
6. It is not recommended to additionally load the sashes with any elements - this will affect their durability.
7. During construction or repair work, protect plastic windows with protective film. Pieces of dirt, debris and plaster can damage the coating and give it an unsightly appearance.

Advice! It is worth checking the correct operation of the parts immediately after installing plastic structures, because often even the craftsmen who perform the installation make mistakes. Take a good look at the fastening of the plastic windows and the correct installation of the fittings, and determine whether the structure is sagging. If you encounter any comments, immediately notify the technician so that he can make adjustments. This way you will personally verify the quality of the services provided to you and be confident in the durability of the purchased product.

Tools and places for adjusting plastic window fittings

We recommend that serious breakdowns and malfunctions be adjusted by specialists from the Windows Expert company ()

The most common malfunctions that can be dealt with without the help of a specialist:

• When closing, the transom touches the frame from below or from the side.
• The fit to the transom frame is not tight enough.
• The locking bars are worn.
• When the sash is open in the “closed” mode, the window frame does not open due to the handle being blocked.
• The handle, loosened, does not fit tightly to the frame or is very difficult to turn.

You can troubleshoot using the following tool:

• pliers or pliers;
• hex key (size 4 mm);
• flat and figured (phillips) screwdrivers;
• a set of “star keys” for adjusting the clamping force;
• scissors for cutting the seal;
• oil can for lubricating fittings.

Pressure density adjustment

Adjusting plastic windows for winter

Before the onset of cold weather, many people want to make sure that the windows are closed more tightly and do not allow the slightest cold draft into the house. If the sash is pressed weakly, you may find that the flame of a lit candle or match brought to a closed window fluctuates greatly and even goes out.

The photo shows the end side of a window sash with fittings; the pressure adjustment mechanisms are clearly visible.

The clamping mechanisms are called locking pins (eccentrics). When the handle is turned to close the sash, they move behind the pressure pads located along the perimeter of the frame. Each sash usually has three eccentrics, which are set to the same position (by default, to the middle, universal position). To strengthen or loosen the pressure, they need to be rotated and moved. This adjustment of plastic windows is not difficult to do.

In different models of fittings, the trunnions can simply be turned using pliers or a wrench (standard), and also have a hole for a hex key. Some models use mechanisms that are adjusted without tools at all - the eccentric is pulled out by hand and locked in the desired position.

If you move the eccentric rollers, turning them clockwise, the sash will be pressed against the frame more strongly, and if it is counterclockwise, it will move away from the frame, reducing the pressure. There are often small stripes on the surface of the trunnions, which make it easier to determine the degree of pressure. The closer the strip is to the seal, the stronger the pressure on the sash. The adjustment range of the trunnions is ± 2 mm. In some designs of window fittings, the clamping density is adjusted by twisting special plates located on the window sash with a key.

In addition, there is a clamping mechanism on window hinges. There it is also adjusted using a hexagon. When the key is rotated (counterclockwise when the hinges are on the left, or arrow when the hinges are on the right), the tongue extends, increasing the pressing density of the sash. On the hinges, the clamping adjustment stroke is ± 0.8 mm.

When preparing for the winter period, it is better to maximize the density of the window sashes to the frame.

In the summer, it is recommended to loosen the pressure to a medium or minimum value to provide greater air access and reduce wear on the seals

When making adjustments, it is important to ensure uniform pressure along the entire perimeter of the window, so each pin must be twisted in the same direction and set to the same position.

Professionals in the repair of plastic windows warn that it is better to adjust the pressure density in the minimum ranges, especially for the first time. The fact is that the seals on the sashes wear out over time, dry out, and you have to press harder and harder. If you squeeze them too hard from the very beginning, the rubber will lose its properties much faster. Then the situation will be corrected not by adjusting the pressure, but by replacing the sealing tape. By the way, there is nothing complicated about this: the old rubber is removed, and the new one is inserted into a special groove.

A worn rubber seal is easy to replace: the old rubber is removed and the new one is inserted into a special groove

To do everything correctly, we recommend that you additionally look at what the trunnions (eccentrics) look like and how the sash pressure changes when adjusting plastic windows in the following video. This will make it easier for you to carry out the necessary preparation of windows for the winter season.

The sash catches the frame from below

If the sash catches the frame from below, then the structure is sagging

After some time of operation of PVC windows and doors, the sash of the frame is observed to catch. This fact indicates that the structure had time to sag.

In case of such violations, adjustment of the top hinge of the plastic window is necessary. When eliminating defects in the operation of the window sash, it is necessary to move it towards the top hinge and from bottom to top, thus eliminating the sagging. The adjustment scheme is as follows:

1. First, let's open the door.
2. We adjust the adjusting screw, which is located next to the top hinge at the end of the sash. This process is carried out using a hex key, which is turned clockwise.
3. Remove the cap on the bottom hinge and use the key to turn it a couple of times clockwise.
4. We check the degree of adjustment of the valves, and if the defect cannot be completely eliminated, we carry out these actions until the desired result is achieved.

Winter-summer mode adjustment

Adjusting plastic windows to winter-summer mode is easy without the help of a specialist. To do this, the position of the trunnions changes, weakening or strengthening the pressure of the sash to the window frame.

What does the trunnion look like?

For convenience, you can watch the training video:

Factories that produce plastic window structures provide a middle position of the axle.

The sash does not press very tightly, but it also does not let air from the street into the room when closed.

Switching the window to the “winter” state

In winter, maximum pressure of the sash against the frame is necessary. Changing the position of the eccentric will increase the load on the seal. The trunnion is pulled back a little and moves to the right.

Difference between winter and summer mode

The distance from the fittings to the roller should be minimal. Correct installation can be checked by the notch on the roller - it should be directed towards the seal.

It is worth considering that windows that have been installed recently are not recommended to be placed in the “winter” position.

Changes in the rotary-locking mechanism during the winter deform the sealing material. It may not recover in the spring.

Transition to the “summer” state

By mid-spring, comfortable weather sets in; the PVC window should be moved to the summer position. To do this, the trunnion is pulled back and moved to the left. The notch will help to translate the roller correctly.

After moving the pin, it should face the window handle.

Types of trunnion positions

After adjusting the trunnion, the load on the sealing material decreases, resulting in an increase in air flow from the street.

Replacing the seal

This procedure is required if it is blowing from the window. Everything is done simply: the unusable seal is pulled out of the grooves, and a new one is inserted in its place. There is no need to stretch it. If you hear squeaking, use silicone lubricant. Frequent replacement of this element is not required: usually it is needed no more than once every ten years.

With the right approach, adjusting metal-plastic windows will not cause any difficulties, even if you have no experience in such matters.

Elimination of improper operation of handles

If there is a need to replace an old handle, install restrictive elements, or fix a loose handle, you should not immediately call specialists to your home. Adjusting plastic windows and balcony doors with your own hands can be done in a matter of minutes if you know the features of their functioning.

Installing a new handle

This activity is not always caused by a broken handle. If children live in the house, they can easily open the doors and climb out. In this regard, it is advisable to install these fittings with special limiters that prevent the free opening of windows. For details on installing the handle, watch this video:

To perform the replacement, rotate the handle to the open position, unscrew the protective plastic to the side and remove the screws using a screwdriver.

The new handle is installed by performing the same steps in the opposite direction.

What to do if the handle is jammed

It is not uncommon for the handle to jam when turning the handle. Don’t immediately panic about replacing this piece of hardware. In most cases, jamming is caused by blocking of the element to prevent damage to the entire window system.

How to turn the handle correctly

Before performing any actions, you should determine the markings of the fittings. As a rule, its name is displayed on the closures of the product.

The procedure for removing the handle from a jammed state in various types of fittings:

1. “AUBI” - we find a spring metal plate and press it against the seal, after which we try to turn the handle to its original position (when performing this activity, all work is carried out in a strictly vertical state, any deviations from the norm can lead to the operation of the upper lock);
2. “ROTO”, “GU”, etc. - find the metal tongue (as a rule, it is located slightly below the handle) and press on it. As a result, it should be installed in a position parallel to the rubber seal, and the handle should turn freely.

During prolonged use of the windows, as a result of repeated temperature influences, the tongue may not reach the mating part, and the rotation of the handle will be blocked. In this case, you should move the response element towards the tongue, unscrewing the retaining screws and placing a piece of durable material (plastic scraps, a small washer, etc.).

Adjusting the fittings

Let's start adjusting the PVC window fittings. Screwdrivers and a hex wrench are mainly used for these purposes. The handles are mainly adjusted using screwdrivers, and the strike plates are adjusted using a hex wrench. If the sash does not press well, then the bar is shifted to the side of the street.

The degree of pressure is also adjusted from the side of the hinges, where the mechanism, adjustable using a hex key, is located. The degree of pressure is set using the tongue. The more it extends, the better the sash will press. Let's consider other cases when adjustment of window fittings is needed. To learn how to adjust the sash pressure, watch this video:

Setting the handle that is blocked when the sash is open

Euro-window fittings work in such a way that when the structure is opened, the handle does not turn to the “closed” position. For this purpose, special locks are provided in the fitting mechanism.

In case of certain malfunctions of the handle, a situation may arise when the handle is turned in the “closed” position, and the structure is open. That is, the blocker fixed the position of the handle. To correct this situation, you must press the locking device and turn the locking mechanism to the “open” position.

The handle doesn't turn

How to adjust plastic windows with your own hands if problems arise with the handle? It jams or it is impossible to turn it.

With such a defect, the process of coupling the locking mechanism with the mating element is not carried out. This problem can be solved in two ways:

• the sash is moved using an adjustable screw to the response mechanism;
• the fastening is loosened and a plate of dense material is inserted between the sash and the frame.

The handle is broken

If the handle fails, you can repair the plastic windows yourself. The repair begins with the locking mechanism being released by removing the lining.

To do this, you need to pull it back a little and turn it 900. Next, you need to unscrew the fasteners that hold the device in place, and install a new handle in its place. For more information on adjusting the handle, watch this video:

The handle turns poorly

Mechanical adjustment of plastic window fittings is not always necessary. For example, poor functioning of the handle of a plastic window is mainly due to poor lubrication of the mechanism.

1. Check seals regularly to prevent wear.
2. When removing all plugs, work should be done very carefully so as not to spoil their appearance.
3. If the frame is deformed, you will not be able to adjust the windows yourself. In this case, you will have to contact specialists. It is better not to repair PVC windows yourself.

An important factor in the long-term functioning of metal-plastic structures is the installation of products from generally recognized manufacturers. For example, install “Rehow” windows in your home; the quality of these products has been tested over the years. For more information about adjusting a PVC window, watch this video tutorial:

To avoid the appearance of defects in the fittings of plastic windows, all rubbing parts should be regularly lubricated.

Types of adjustment mechanisms

The degree of pressing of the sash to the frame is adjusted using locking mechanisms (trunnions) located on the side and upper ends of the sash. The appearance, quantity and location of these devices may vary depending on the manufacturer and price category of the double-glazed window.

The most common ones include:

• Round. Such trunnions have some kind of mark (dash, mark, dot, asterisk). If it is directed towards the room, then the window is set to “winter” mode, to the street – “summer”, upward – “neutral”.
• Oval. The vertical position is “summer”, the horizontal position is “winter”, the diagonal position is the standard “neutral”.
• Turnkey eccentrics. The shift into the room is “winter” mode, outward is “summer”, strictly in the middle is “neutral”.

Winter/summer adjustment

The tightness of the sashes must be adjusted to ensure that the windows close equally tightly and easily both in winter and in summer. After all, the seal also expands and contracts depending on weather conditions. Therefore, the window design provides the ability to adjust the tightness of the fit. So that the windows fit as tightly as possible in winter, and close easily in summer.

To adjust the tightness of the window, its design has special eccentrics. They are the ones who regulate the tightness of the fit. They can be in three positions, maximum, medium and minimum fit.
To adjust the tightness, simply turn the eccentric to the desired position; this can be done using a hexagon, screwdriver or pliers, depending on the design of the eccentrics.

Adjustment of the tightness of the window should be carried out in the off-season, twice a year. This will help you avoid blowing.

In this video you can watch the main points of window adjustment technology. We recommend that you familiarize yourself with it before you start adjusting the plastic window in order to avoid errors in operation and quickly achieve the result you need.

Adjusting plastic windows is a simple procedure in itself, since the windows have a well-thought-out design. Therefore, you can easily do it yourself with due diligence. The most important thing is not to rush and not turn the adjusting bolts several turns at once. In addition, adjustments must be carried out in a timely manner, as this is the key to the durability of all fittings.

Handle repair and adjustment

Active use of the window, constant impact on its main mechanism - the handle - leads to various types of breakdowns. In such cases, calling a specialist is not required, since adjusting the handle on a plastic window is very simple.

Loosening

If the handle becomes loose, just tighten the two bolts hidden under the plastic decorative cover. To dismantle it, no tool is required - just pull the handle towards you and turn the part 90 degrees. The bolts are tightened with a Phillips screwdriver, then the fittings are returned to place.

Jamming

If the handle turns with force or does not move into standard positions, the cause is usually clogging of the mechanisms. In this case, you should unscrew the handle and clean all moving parts of the structure with WD-40 aerosol. After this, the window is lubricated with machine oil.

Adjusting the plastic window handle

In addition, the reason for poor window functioning is sometimes:

• incorrect position of the plastic window sashes - do-it-yourself repair and adjustment in this case consists of changing their position using a hex key, as described above;
• if the handle does not fit well into the “closed” position, this indicates that the sash is being pressed too hard against the frame - it is necessary to adjust the trunnions around the entire perimeter, loosening them a little.

Jamming

The handle getting stuck in one position is a consequence of the locking mechanism. It is necessary so as not to break the fittings - the metal locking tongue prevents, for example, opening a window when it is in ventilation mode. However, the blocker sometimes works at the wrong moment, preventing you from closing the window. This happens due to improper handling - too sudden a change in the position of the handle.

Adjusting the handle of the plastic window in this case depends on the manufacturer of the fittings:

• The lock is disabled as follows: the sash opens, there is a metal plate near the handle, which you need to press on and turn the handle in any direction.
• Maco et al. There is a steel tongue underneath the handle that sticks out at an angle when in lock mode. You need to press it, placing it in the “parallel to the frame” position, and change the position of the handle.

Replacement

If the standard handle is damaged or it needs to be replaced with a locking mechanism, you can install a new part yourself. This is done very simply:

• The plastic protection is removed from the old handle.
• Two cross bolts are unscrewed.
• A new handle is installed and screwed on.

Such installation and repair of plastic window fittings does not take much time, and a new part can be found in any hardware store.

Thus, everyone can cope with the work, since you can adjust plastic windows with your own hands quickly and without the use of complex tools.

Pressure density adjustment

Setting the pressure on a plastic window is quite simple if you follow a simple sequence of actions. Find in the area of ​​the handle, located at the side end, a system of eccentrics that serve as the main adjustment tool.

Winter and summer mode can be adjusted using trunnions

Their external design may be slightly different depending on the window manufacturer, but the principle of operation is the same, whatever their type.

Options for the appearance of eccentrics

Using a hex wrench or pliers, the desired degree of pressing of the sash is adjusted by rotating the eccentrics. In the summer, manufacturers recommend setting weak modes, switching to strong ones closer to winter. Read more about this in the article about converting windows to seasonal modes.

When it is necessary to adjust the pressure on the side of the window hinges, you need to refer to the adjusting screw located on the bottom of the hinges. For tilt-and-turn sashes, additional adjustments are made using the top hinge.

In order to successfully get to the adjustment bolt located on the scissors next to the top hinge, you need to open the window, press the locking tab and set the handle to the ventilation mode. When it is necessary to press the sash against the window frame, the bolt rotates clockwise. Rotating in the opposite direction will weaken the seal.

By adjusting the tilt-and-turn scissors, you can adjust the degree of window pressure

The method of adjusting window fittings depends on the manufacturing company, since there are varieties that are adjusted with screwdrivers located on the side of the handles. Others only fit hexagons. In order to increase the pressure, the bar is carefully shifted to the street side. If you look at the hinges, you will notice retractable clamping elements. A smaller extension will provide a loose fit, while a larger extension will press the sash tightly against the frame.

Adjusting the hinges

In most cases, plastic window designs are not equipped with a window. The ventilation process can only be carried out after the sash is set to a certain mode.

Too large a gap between the sash and the frame in extreme cold will contribute to strong cooling in the room.

It is necessary to find a “golden mean” so that the gap during ventilation is somewhat smaller. Therefore, you can adjust the pressure of the window hinges so that there is no draft. First you need to determine the location of the blower. If this place is located near the bottom hinge, then a hexagon is needed. You need to remove the cap and start adjusting according to the instructions.

The sash must be set, the handle must be turned to ventilation mode and the top hinge must be pressed. When the window is closed, it is impossible to reach the screw responsible for the degree of clamping of the hinge.

Some window designs have special blockers that disable the ability to open the window. If the handle dangles, this will only make the problem worse.

You need to slightly lift the plastic plate located next to the base of the handle, and then rotate it 90 degrees. After this, the screws will be visible, which need to be tightened with a screwdriver until they stop.

If the handle does not turn well, then you need to lubricate the fittings with machine oil: eccentrics, hinges, clamping mechanisms.

You need to check the fittings and window structure at least once a year, even if nothing bothers you about its operation. Adjustment will allow you to quickly solve problems yourself.

Hinge adjustment in vertical and horizontal direction

If the middle or lower part of the transom catches the window frame due to sagging of the sash, this can be eliminated by adjusting the rise of the horizontal or vertical regulator.

• Adjust horizontally using the top or bottom loops. When the window frame is open, by inserting a hex key into a special hole and rotating it to the right, the sash will be attracted to the hinge, and the lower corner opposite this hinge will rise. When rotating in the opposite direction, the transom moves away from the hinge, and the corner opposite the upper hinge is lowered.
• The lower hinge can be adjusted from the inside when the window frame is open, and from the outside when it is closed. The adjustment is carried out similarly to the upper loop. These methods can move the frame or eliminate the bevel.
• Vertical adjustment is carried out using the lower hinge by rotating the key in the hole of the adjusting hexagon hidden under the cap of the lower hinge.

When rotated to the right, the frame rises, and when rotated to the left, it lowers.

If the handle is faulty, should I change it or can I do something?

Handles on plastic products are subject to the greatest load. We constantly open and close windows and do not always do it carefully

The result of such carelessness is the loosening of the handle. It's very easy to fix this situation.

Find a rectangular trim under the loose part, pry it up with your fingers (do not use metal tools, as they can damage the edge of the plug or even the profile itself) and turn it 90°. Bolts will open in front of you. Use a Phillips screwdriver to tighten them, then return the trim to its place.

Self-repair of PVC windows

It is more difficult to cope with a handle that does not reach any given position or noticeably jams. First, dismantle the closing mechanism, thoroughly clean its internal parts, and then treat them with oil (machine oil). If this does not solve the problem, try reducing the clamping force on the sash. You will need to adjust the hooks and trunnions. We discussed this technique in detail in the previous section of the article.

Sometimes the handle gets stuck. There is an opinion that such a malfunction definitely requires replacing the device that closes the window. This is wrong. Moreover, you don’t even have to dismantle the handle to wedge it. The problem in this case arises because the locking device on the PVC structure does not work correctly. The problem can be corrected simply - at the end of the sash, find the locking lever (it can be made in the form of a clip or in the form of a small tongue) and carefully move it away. This is all. The functionality of the pen has been restored!

The fold catches the frame from the side

Adjust the screws with a hex wrench

Opening a PVC window when the sash touches the frame leads to problems. The window device will not be able to open and tilt freely. Do-it-yourself window adjustment in the case where the sash catches the frame on the side is carried out according to the following algorithm:

• When the sash hooks the frame only from below, it is necessary to move it towards the hinge in its lower part. This is achieved using the adjustment screw, which is located under the lower hinge;
• When the sash catches the frame around the entire perimeter, it is necessary to adjust the screw, which is located at the end of the sash next to the top hinge.

Disadvantages of Changing Window Modes

The adjusting screws are essentially locking pins that are designed to tighten the window seal. Constantly adjusting them is fraught with loss of the basic properties of the seal and the need to replace it.

When the window is opened with a handle, the trunnions move along the guides and the eccentrics move behind the counter strips and provide pressure to the profile against the frame. When tightening the screw for the winter, maximum force is provided on the seal, and it remains in this state all winter.

At the same time, it is additionally affected by low temperatures and increased moisture. Over the course of 2-3 seasons, it may completely lose its properties. If you do not change the winter-summer regime, the seal can last at least twice as long.

Performing winter-summer adjustment

Adjusting the window for winter

Adjustment of plastic windows in winter and summer can be carried out without the involvement of specialists, which will significantly save the family budget. When answering questions about how to adjust plastic windows, how to properly configure the control elements, how to switch windows to winter mode, you should refer to adjusting the trunnion, increasing or decreasing the pressure of the sash on the PVC window frame using a pressure plate.

In production, manufacturers initially install the eccentric in an average position, which provides a seemingly fragile connection between the window and the frame, but does not allow air flows from the street space into the house when closed.

The presented average adjustment of the trunnion is typical for the summer season, when precipitation does not enter the small gaps between the sealing rubber bands and the window structure.

Adjusting windows to the “winter” position

In advance of the first frosts and the arrival of negative temperatures during the day, optimal contact between the sash and the frame should be ensured. At the same time, when answering the question of how to adjust plastic windows for the winter, you should remember that when the trunnion is tightened, the pressure on the intermediate sealing rubber bands increases. In the “winter” position, the position of the eccentric is slightly shifted to the right and pulled towards itself.

When performing this activity, the following features should be taken into account:

• the distance from the roller part to the corresponding fittings should be minimal (the proper position of the windows and the correctness of their assembly can be determined by the notch on the roller, which is directed towards the sealing rubber);
• if windows are installed in the current calendar year, window adjustments are not required;
• excessive compression of the seal by the action of the pin on it can lead to deformation of the rubber bands and the appearance of gaps between the windows and the frame part.

Adjusting windows to the “Summer” position

With the arrival of the warm season, when the optimal temperature regime is established, the windows should be switched to the summer position on their own. To implement this measure, you should pull the trunnion and move it slightly to the left. At the same time, it is necessary to monitor the mark on the roller element at the time of transfer.

For ideal window adjustment, the position of the pin after displacement should be directed towards the window handle.

Having completed the described action, the pressure on the sealing rubber is reduced, resulting in optimal circulation and air flow into the room. For details of winter-summer adjustment, see this video:

Adjusting the roller positions should be done for PVC windows of all types and modifications. This circumstance is due to the frequency of use of window structures in winter and summer. Due to the fact that in summer the ventilation window opens more frequently, it is necessary to provide favorable conditions for the functioning of the sealing gum (it should not experience excessive loads and changes in its structure).

Horizontal and vertical adjustment

On the horizontal side, the sash is subject to adjustment in the event of a bevel of the frame caused by shrinkage of the structure, incorrect opening of the window or loose fastenings of the fittings. To fix the problem, you need to insert a hex key into the upper window hinge, turning it clockwise until the sash moves a sufficient distance away.

Adjusting the top canopy

In this case, the lower part of the opposite element should drop noticeably. The lower hinge is adjusted from the outside. The shifts average 2 mm.

Diagram of the main position correction points

The window can be adjusted vertically using the hinge located at the bottom of the frame. The protective cap is removed from the loop and the rotational movements of the tuning mechanism begin. Moving the tool in a clockwise direction will raise the sash, moving it in the opposite direction will lower it.

Adjusting the sash height

Adjustment of plastic structures should occur smoothly so that the mechanisms move no more than 1 mm in one approach.

Troubleshooting let's get to work

Problems with window fittings most often arise as a result of the use of low-quality components or as a result of careless operation. We suggest considering ways in which you can adjust plastic windows yourself.

1. Problems with turning the handle. If the window handle becomes difficult to turn or is stuck, it is most likely due to dried grease. As a rule, manufacturers recommend lubricating moving parts (eccentrics, hinges, pads and clamping mechanisms) every year. For this, both regular machine oil and lubricant specifically designed for window structures are suitable. Silicone lubricants in the form of an aerosol WD-40 are very convenient for use.
2. The handle is loose. In order to secure the window handle in the socket, it is enough to turn the plate at its base at a right angle. Screws will open under it, which need to be tightened with a screwdriver. If the handle is broken and needs to be replaced, the procedure is the same: turn the plate 90 degrees, unscrew the screws, remove the old handle, attach the new one, tighten the screws. Adjusting plastic windows will not take much of your time; the main thing is to do everything very carefully and act according to the instructions.
3. The window sash does not fit tightly. This is one of the most common types of defect, as a result of which it begins to blow from the window, and moisture and precipitation in the form of rain or snow get onto the window sill. What to do in this case? The cause of drafts and moisture leakage may be a poor-quality seal or a seal that has lost its performance properties. In this case, the adjustment comes down to replacing the old seal with a new one. This is done quite simply: the old one is removed from the grooves, the new one is placed in a special plastic recess. At the same time, try not to deform the material, otherwise this will lead to a reduction in its service life. With an average warranty period for windows of 40-50 years, the seal must be replaced every 10-15 years. If the adjustment method described above did not help solve the problem and the sash still does not fit tightly, you can adjust the degree of pressure using a hexagon, screwdriver or pliers. Plastic windows are also adjustable depending on the season: in winter the degree of sash pressure can be increased, and in summer it can be weakened.
4. Adjustment of the upper or lower hinge horizontally. Both the top and bottom hinges have holes for a hex key. If you need to adjust a plastic window in the horizontal plane, you need to understand what needs to be done - raise the bottom of the window, or, conversely, lower it. In the first case, using a hexagon, rotating it clockwise, we pull the sash towards the hinge. In the second, turning the key counterclockwise, lower it slightly. In the same way, you can make adjustments and eliminate skew in the horizontal plane.
5. Adjustment of the upper or lower hinge vertically. In order to raise or lower a plastic window sash in a vertical plane, an allen key is inserted into the opening under the lower hinge. To do this, you must first remove the protective plastic cap. If you want to raise the window, the key rotates to the right; if you want to lower it, it rotates to the left. The bevel is adjusted in the vertical plane in the same way. How to adjust plastic windows vertically correctly? You should not greatly increase the width of the sash, because it may sag when opening the windows.

Adjusting windows for the summer season

The end of the heating season usually occurs in fairly warm weather, so the load on the seal is eased using the “summer” mode.

In this case, the impact on the seal is minimal. Therefore, this position of the eccentric is welcome for any windows.

Adjusting the trunnion according to this principle slightly increases the air circulation in the room. However, this begs the question about the need for such a transition, because Windows are ventilated very often in summer. To ensure minimal pressure, window adjustment for the summer season should be done as follows:

• the eccentric should be pulled back slightly
• move it to the left with rotational movements,
• so that the gap between the trunnion and the edge of the sash fittings is maximized.
• If there is a notch on the roller, and in the correct position, it will be directed towards the window handle.

Conclusion

Window adjustment rules

In conclusion, I would like to note that timely, correct adjustment of PVC windows is the key to their reliable and high-quality functioning over a significant period of time. Along with the listed features of the elements and the procedure for converting to summer and winter modes, the metal parts of the window structure should be lubricated in advance using a special penetrating lubricant or machine oil. Taking into account all the listed features, the developer, through correctly adjusted elements of window structures, will provide his home with the most comfortable living conditions.

Most owners of private houses and apartments are interested in how to adjust plastic windows. You can configure them yourself without additional costs, which is why this option is attractive. Although modern designs are made using high-quality fittings, they sometimes require maintenance.

The sash is adjusted using a hexagon

Before you begin adjusting the window, it is recommended that you familiarize yourself with its basic elements. If during operation the smooth functioning of all components is not ensured, then there can be no talk of comfortable use of the structure.

Basic components

PVC window blocks usually include the following parts:

• frame made of plastic profile with steel reinforcement;
• doors that allow opening and closing;
• a double-glazed window, which is a product that is capable of transmitting light;
• bead holding the glass unit in the frame;
• an impost acting as a connecting post located vertically between the sashes;
• rubber seals ensuring tightness.
• shtulp used in conjunction with the above-mentioned element.

The moving elements can be lubricated with a can of WD-40, which is equipped with a convenient tube. Using an aerosol product, it will be possible to properly coat the parts with a layer of oil. It is recommended to lubricate during each seasonal adjustment, regardless of the serviceability of the part at a particular time.

Helpful advice! If regular handles are installed in the children's room, they can be replaced with products with a protective mechanism. A small child, even if he or she wants, will not be able to open the window on his own.

Article

Today I want to talk about how adjust PVC windows. Here you will find both general adjustment instructions, as well as a description of the main problems and ways to eliminate them. I hope that this instruction will help you adjust the fittings of plastic windows yourself.

General information about adjusting plastic windows:

• Adjustment carried out with a 4 mm hex key (No. 4).

• Horizontal adjustment (↔) carried out using the lower and upper loops. For this purpose, there are hexagon holes in the hinges. To get to adjustments top hinge, the window needs to be opened.

By rotating the hexagon clockwise, the sash is attracted to the hinge - the bottom of the window opposite the hinge rises, respectively, rotating counterclockwise, the sash moves away from the hinge and the bottom of the window opposite the hinge is lowered.

Adjustment using the bottom hinge can be done both when the window is closed from the outside, and from the inside when the window is open. Adjustment occurs similarly to the top loop.

With these adjustments you can eliminate the bevel or move the frame, stroke adjustments±2 mm.

• Vertical adjustment (↓) occurs using the bottom loop to get to regulatory hexagon, you need to remove the lower hinge cap.

When rotated clockwise, the window rises, counterclockwise – it lowers. Move adjustments±2 mm.

• Adjusting the sash pressure carried out by eccentrics located around the entire perimeter of the window.

When the handle is turned, the eccentrics move behind special pressure pads located along the perimeter of the frame.

To press the window more tightly to the frame, you need to rotate the eccentric clockwise, to loosen it, counterclockwise.

There should be a mark on the eccentric, by which you can determine the degree of clamping; if it is directed towards the street, then the clamping is weakened, respectively, if the risk is towards the window seal, then the window is pressed harder against the frame.

There are eccentrics that are rotated with a wrench (pliers).

The pressure can also be carried out by plates that are located on the window sash.

On the hinge side there is also a clamping mechanism that regulated hexagon, the more the tongue located on the window sash is extended, the stronger the window is pressed against the frame and vice versa. To pull out the tongue, you need to rotate the hexagon counterclockwise (for a window whose hinges are located on the left, if the hinges are on the right, then you need to rotate it clockwise).

The clamp can be regulate depending on the time of year, in summer - weaken, in winter - strengthen. The stronger the pressure, the faster the seal will wear out. Move adjustments±0.8 mm.

• Adjusting the hinge pressure. Depending on the fittings you can regulate pressing only the top or both loops. For adjustments To press down on the bottom hinge, remove the cap and rotate the bolt located perpendicular to the plane of the window.

Adjustment The top hinge is pressed only on flaps. To get to adjustments you need to open the window and then turn the handle to ventilation mode. It is necessary to hold the window, because it will only be held on the bottom loop.

In this position, it will be possible to reach the hexagon, which is responsible for pressing the upper sash.

There may be a lock on your window that only allows the sash to be tilted in the closed position. They come in two types, in the form of a lever and a clip:

To tilt an open window, you need to press the lock and at the same time turn the handle to the ventilation mode.

The main problems that can be eliminated by adjusting PVC window fittings:

• The bottom of the sash touches the frame. This occurs due to sagging of the window sash and is eliminated by lifting it. This can be done: with a vertical regulator, or one of the horizontal ones.

• The middle part of the sash touches the frame. The problem may arise due to the horizontal (vertical) displacement of the sash. It can be eliminated by uniformly moving the sash in the desired direction using horizontal (vertical) regulators.

• Blowing from under the seal is eliminated sash pressure adjustment.

• Adjusting a loose handle. Rotate the plate at the base of the handle 90° and tighten the screws with a screwdriver.

To eliminate malfunctions, you need to adjust the plastic windows. To do this, you can call specialists, or you can do everything yourself, following the instructions.

A prerequisite for effective performance of functions is correct adjustment. It maintains the tightness of the rebate, the necessary tightness, and the smooth movement of the sash without distortions or touching the frame. The initial adjustment of plastic windows is carried out by installers during their installation. After this, they should work without defects or irregularities. However, over time, small gaps appear and the sashes begin to sag a little. In the future, these deviations intensify, which interferes with the normal operation of the structure.

What tools will you need?

To adjust plastic windows yourself, you will need a fairly simple kit, including:

• Hex wrench No. 4;
• Pliers;
• Phillips and flat screwdrivers;
• A screwdriver with a set of bits of different shapes.

The tools from this set are usually always available at home. An exception may be a hexagon, without which the work cannot be completed - this is the main regulatory tool. If you don’t know what key is needed to adjust plastic windows and where you can find it, then contact any furniture hardware store. 4 mm hexagons are used when assembling any modern cabinet furniture, so finding such a key will not be a problem.

A screwdriver and screwdrivers will be needed to work with the screw connections with which the hardware elements are attached to the profile. Pliers are needed as an auxiliary tool.

Main components that need adjustment

Adjustment may be required for any moving elements of plastic window fittings, which include:

Bottom swivel hinge

Top hinge with tilt and turn mechanism

Locking pins

Do-it-yourself repair and adjustment of plastic windows may be required at several points. In particular, it may be necessary to adjust the sash vertically, horizontally, adjust its pressure to the frame, and set the lower angle correctly

When do you need to adjust plastic windows?

Adjustment of windows is required in case of any violations of their normal operation. The following signs may indicate the need for its implementation:

• Tight movement of the valves;
• Visible subsidence or distortion of the sashes;
• Violations of the tightness of the closure - cracks appear, blowing from the window;
• Switching modes is difficult;
• Loose or jammed handles;

If such signs are detected, it is not recommended to delay taking action. In most cases, you can adjust the plastic windows yourself and quickly restore their normal operation. If you do not make adjustments in a timely manner, soon enough you may encounter a serious malfunction of the window structure, which will cause a lot of inconvenience and require significant repair costs.

Adjusting the pressure of a plastic window

Most often you have to adjust the pressure on the sash of a plastic window. This parameter characterizes the force with which the sash is pressed against the frame when closed. Pressing of the sash is ensured by locking trunnions located at its end part. When the handle is turned, the trunnions move vertically, entering or leaving the mating part located in the frame opening. When the axle completely extends beyond the mate, the sash is pressed against the frame with maximum force. The magnitude of this force is subject to adjustment.

It is recommended to adjust the pressure of plastic windows at least twice a year to switch to winter and summer mode. The maximum pressure is set for the winter. It provides increased tightness and prevents cold air from entering the room due to insufficient sash cover. However, strong pressure accelerates the wear of rubber seals, so it is recommended to loosen it in summer.

It is also necessary to adjust the pressure of the plastic window if there is a blow from the area where the sash adjoins the frame. The reason for this may be incorrectly adjusted pressure or wear of the seals. You can check the presence of draft using the flame of a match or a lighter brought to the window. If the flame fluctuates, adjustment is necessary.

The plastic window does not close tightly - how to adjust

To ensure that the sash closes tightly, you can adjust the pressure of plastic windows yourself according to the instructions.

The trunnion has an eccentric that must be turned in a certain direction to adjust the pressure. Depending on the model of fittings used, there are oval or cylindrical trunnions. In the first case, the adjustment is performed by turning the trunnion itself with pliers. When the oval is positioned in a vertical position, the minimum clamping force is ensured, and in a vertical position, the maximum is ensured.

More popular today are cylindrical pins, which have sockets at the end for a No. 4 hex wrench offset from the axis by 2 mm. In this case, you can adjust the pressure of the plastic window by turning the pin using a hex key. Turning to the left increases the pressure, and turning to the right weakens it. Maximum pressing is achieved when the eccentric is positioned in such a way that the key socket is located on the outer side of the sash. The minimum pressure is achieved in the reverse position of the eccentric - the key socket is located on the inside of the sash.

Another eccentric is located on the underside of the top hinge plate. It must be rotated similarly to the eccentrics of the trunnions around the perimeter of the sash. This will allow you to adjust the pressure in the top hinge area. To access this eccentric, the window must be open in two positions. First, you need to open the sash and switch it to ventilation mode by pressing the lock lever.

To evenly press the sash around the perimeter, all eccentrics on the trunnions must be in the same position. Uneven pressing accelerates wear of the seal and leads to a violation of the tightness of the closed window.

How to adjust a plastic window so it doesn't blow

In some cases, adjusting the window trunnion does not allow achieving the tightest possible pressure, and the closed sash continues to blow. This occurs when the sash moves vertically or horizontally. As a result, part of the trunnions may not completely extend beyond the mating part.

To determine the place where incomplete pressure is created, you need to remember the locations of the trunnions or make corresponding marks on the inside of the sash profile. After this, you need to close the window and, in the marked places, try to press the sash away from the frame with your hands. If it remains motionless, then the trunnion is working properly. If the sash moves, and a gap appears at the point where the force is applied, then the trunnion does not completely fit into the mating part. In such cases, additional adjustment of the plastic window sash horizontally and/or vertically is required.

Adjusting the plastic window horizontally

To eliminate slight distortion and displacement of the sash in the horizontal plane, you need to adjust the plastic window horizontally. This adjustment can be made on the upper and lower hinges, which have special hexagon sockets. Therefore, you can adjust the position of the sash using the same 4 mm hex key that was used to adjust the trunnions on plastic windows.

On the bottom hinge, access to the hexagon socket is available from the outside and inside. Thanks to this, you can adjust the window both open and closed. When you turn the key clockwise, the sash will move in the direction opposite to the hinge, while its lower corner on this side will rise. Turning the key counterclockwise causes the sash to move towards the hinge, and the lower corner on the opposite side is slightly lowered.

Horizontal adjustment of the plastic window sash can also be done on the top hinge. In this case, work is carried out only with the window open. On the hinge you need to find the hexagon socket and turn it with a key in the same way as working with the lower hinge.

These manipulations will allow you to move the upper or lower part of the sash horizontally up to 2 mm. It is recommended to adjust the sash with limited displacements - no more than 1 mm per turn of the key.

Adjusting the plastic window vertically

Self-adjustment of plastic windows vertically is performed on the lower hinge. The required hexagon hole is located at the top of the hinge, so to access it you need to remove the decorative plastic cap. For ease of adjustment, it is recommended to switch the window to ventilation mode. Turning the key clockwise raises the sash, and counterclockwise causes it to lower.

As with the horizontal adjustment, the window sash movement range is 2 mm.

Replacing the handle and adjusting the fittings of a plastic window

In addition to insufficient pressure and airflow, other problems may arise in the operation of a plastic window. Often during operation, problems may arise with turning the handle, which moves slowly when switching modes or even gets stuck in a certain position. Therefore, owners need to know how to properly adjust plastic windows themselves in such cases.

One of the common causes of such problems is a faulty handle. Most often it just becomes loose and starts to wobble. In case of such a malfunction, it is enough to tighten the fastening screws. To access the screws, you need to pry the decorative plastic trim on the handle body from above and below with your fingers and turn it horizontally.

Stiffness of the handle can be caused by clogging of its mechanism. To remove dirt, the handle must be removed by unscrewing the fastening screws and cleaned with a brush or vacuum cleaner. It is recommended to lubricate the seat of the handle inside the door with WD-40 aerosol lubricant with a nozzle. Another reason why the handle turns tightly may be that the sash is being pressed tightly. If it is not necessary to maintain maximum pressure, it is recommended to adjust the trunnions by reducing the force.

If the handle does not turn at all, this is most often due to incorrect operation of the lock, which is designed to prevent it from turning when the sash is open. To unlock the handle, you need to find the lock and release it. Depending on the model of fittings used, the blocker can be made in the form of a clip that fits onto the seal, or in the form of a shaped plate screwed at an angle to the seal.

The solution to the problem in case of severe wear is to replace the handle. You can find a new part in almost any hardware store or order it from a window manufacturing company. All handles have a standard design, so there will be no problems with selecting a suitable element. After this, you just need to dismantle the old handle and put a new one in its place.

The plastic window closes tightly - how to adjust

If the plastic window does not close well, self-adjustment will also help eliminate the problem. The reason is usually the misalignment of the sash, as a result of which it touches the frame when opening or closing. To solve the problem, you need to eliminate the skew by adjusting vertically or horizontally. First of all, you need to carefully inspect the window to determine the place where the sash comes into contact with the frame. Contact between surfaces usually occurs on the bottom edge or on the side edge of the sash on the side opposite the hinges.

If the sash rubs the frame from below, it must be moved up and towards the corner adjacent to the top hinge. To adjust a metal-plastic window with your own hands, you need to open the sash and turn the adjusting screw of the top hinge clockwise a few turns. After this, you need to close the sash, remove the decorative cap from the lower hinge, insert the hex key into the hole of the adjusting lift and turn it several turns clockwise. After adjusting the PVC window, you need to check the movement of the sash. If necessary, repeat the manipulations.

If the sash comes into contact with the frame when opening and closing, then adjusting the fittings of a plastic window with your own hands involves moving it towards the hinges. If there is friction only on the lower side of the side edge, it will be enough to tighten the adjusting screw, which is located in the lower part of the lower hinge on the side, with a hex wrench. If the sash rubs the frame along the entire height of the side surface, then it must be moved additionally towards the upper hinge. To do this, you will have to tighten the adjusting screws on both hinges. After completing the work, you need to check the movement of the sash. If its friction on the frame is not completely eliminated, the adjustment manipulations must be repeated.

PVC window lubrication

A significant part of the violations that require adjustment of the mechanism of plastic windows occurs due to its poor lubrication. In new windows, the fittings are coated with a sufficient amount of lubricant for effective operation. However, over time, these compounds degrade and lose their properties. These processes occur especially intensively in houses that are located near busy highways, industrial enterprises, and other sources of air pollution. Dust settles on the moving elements of window fittings and penetrates the lubricant, which significantly deteriorates its quality. This leads to jamming of the mechanisms and their accelerated wear. Therefore, adjusting old plastic windows always involves lubricating them.

To prevent accelerated wear of fittings and complex repairs, you need to lubricate them at least once a year. It is best to lubricate windows twice a year - before the onset of the winter and summer seasons. In addition, it is recommended to lubricate after carrying out any maintenance work on any hardware elements, for example, after adjusting the scissors of a plastic window, hinges or pins.

What to lubricate with?

Special compounds are used as lubricants for servicing plastic windows, which are sold in specialized stores or can be ordered from window suppliers. They are supplied in bottles with convenient attachments designed to work with certain elements of fittings. If such special lubricants are not at hand, you can use technical petroleum jelly and any technical oils, for example, sewing machine oil. Silicone grease or aerosol lubricants such as WD-40 can also be used. The use of edible, cosmetic and other types of oils that are not intended for use with mechanisms is not allowed.

To achieve maximum beneficial effect, the lubricant should be applied to clean and dry metal surfaces. Therefore, after adjusting the window fittings, it must be thoroughly cleaned of any dirt and wiped with a soft cloth. Dirt from hard-to-reach places is removed with a brush or sponge. Before applying the lubricant, it is recommended to further inspect the window fittings to ensure they are clean.

What to lubricate?

Lubricant is applied to all moving elements. Lubricated including:

• “Scissors” of a plastic window;
• Hinge adjustment mechanisms;
• Fastenings;
• Latches, etc.

A few drops of lubricant are applied to each of the moving parts. After this, I let the mechanism work in normal mode to distribute the lubricant evenly.

In addition to the mechanisms, rubber seals must be lubricated. For this, a special composition is used. The lubricant maintains the elasticity of the rubber and prevents it from drying out. It is better to treat seals twice a year. Be sure to lubricate them in the fall when adjusting the pressure of a plastic window with your own hands in winter mode.

Regular lubrication of window fittings will extend its service life and eliminate unnecessary repairs and adjustments. In some cases, it serves as an alternative to adjustment work. For example, before adjusting plastic windows that do not close well, it is recommended to lubricate the fittings. In many cases, this is enough to solve the problem.

At the moment, plastic windows are popular products for many users. Almost every apartment has PVC windows installed in at least one room. During operation, various problems may appear. For example, the handle may not turn, the windows may stick, or there may be other problems with closing and opening the windows. To solve these problems, you need to know how to adjust plastic windows.

Plastic windows may stop functioning properly not only due to long periods of use. If we take into account the average service life of windows (more than 15 years), then the owners of these double-glazed windows are unlikely to encounter any difficulties. But problems happen, and very often. If it is not possible to call a specialist or you do not want to spend extra money on repairs, then you can do the basic work of adjusting PVC windows yourself, which will allow you to get rid of a large number of problems.

For what problems and when is adjustment required?

You need to adjust plastic windows yourself as needed. If a certain problem arises, you need to immediately look for effective ways to eliminate it. Even if the initial “calibration” is done correctly, problems may arise later. They are associated with deformation of fastening elements, improper operating techniques, violation of tightness, structural integrity, etc.

By self-adjusting plastic windows, you can eliminate the following problems:

• The handle turns with difficulty or does not turn. The cause of the problem is a lack of lubrication or the sash being lowered. To solve the problem, you need to lubricate all moving elements, then remove the plug. Use a screwdriver to determine where the moving roller is moving incorrectly. After identifying the problem, you need to tighten the screw with a screwdriver.
• The handle is loose. Problems arise with fittings all the time. They are resolved in a couple of minutes. Here is the plate, which is located under the plug. It rotates 90 degrees. To solve the problem, you need to tighten it with screws using a suitable screwdriver.
• When torn off, the middle part of the sash catches the frame. Often the reason lies in the vertical or horizontal displacement of the sash. The situation can be resolved by calibrating the sash lift.
• The lower part of the sash is sagging, and when opening it touches the frame. This problem is quite common and occurs when sash windows sag. This problem can be solved by vertical or horizontal adjustment of the sash lift.
• Blowing. In cases where a slight draft begins to be felt from under the insulation, you need to independently adjust the sash pressure.

If you cannot independently and accurately understand the reason, you need to seek help from a professional. It's better to pay for minor repairs than to replace broken parts later.

Tools required for adjustment

To adjust plastic windows yourself, you need a few tools. When setting up, use:

• Pliers.
• Phillips screwdriver size 3 or 4.
• Star and Phillips screwdriver bits (often they should be marked “TX” or “T”).
• A set of hexagons (a 4 mm hexagon must be included in the kit).
• Regular machine oil and universal WD-40 aerosol.

Basically, only a hexagon is used; in everyday life it is called a furniture key. This metal small hexagonal rod has an L-shape. For convenient use it can be S-shaped.

Star attachments are needed to work with certain models of fittings. Because of this, it is better to use several similar attachments. Craftsmen often fasten fittings with ordinary screws using a Phillips screwdriver, so this is what you will need for adjustment.

The adjustment process is greatly simplified if the operation of the sliding windows is impaired. In this option, all work comes down to setting up the roller carriages, which are intended for attaching the sash.

The main adjustment points for metal-plastic windows

There are a total of 5 adjustment points on the window that allow you to make the correct settings. Let's look at how to adjust plastic windows:

• The upper part of the sash is adjusted horizontally in the area of ​​the upper hinge.
• The lower angle of the sash in the area of ​​the lower hinge is adjustable horizontally.
• The place for adjusting the vertical position of the sash is located in the lower hinge.
• In the area of ​​the eccentric locking pin, the pressing force of the sash is adjusted.
• Another way to adjust the sash pressing force is to adjust the lower locking pin.

Using the above points, you can calibrate all possible window positions. All manufacturers use standard window models, so if your plastic double-glazed windows are not made to order, there will be no difficulties in adjusting each point.

Immediately after searching for these points, you should check them for deformation. If deformations are present, then you should immediately contact a specialist. If garbage is found, you should remove it and try again the action that was previously performed with difficulty.

Adjusting the pressure of the window sash to the frame

If the plastic windows you are using do not close properly, and the sashes are not pressed tightly against the frame, then you will need to adjust the plastic windows yourself.

This work is performed using a hex key, which must be turned in one of the directions:

• Down or up from the frame.
• Left or right.
• Adjustment of sash pressure density.

In some cases, problems with closing windows occur due to shrinkage of the house. When inspecting the window, you need to pay attention to the eccentrics that are installed around the perimeter and are part of the window fittings. They will move and move past the pressure pads being used when you try to turn the handle.

To navigate the degree of pressure, you need to pay attention to the marks on the eccentrics. If the lines point towards the street side, then the clamp is weak, but if on the contrary, then the clamp is too tight.

If the clamping mechanism is located in the same place as the hinges, then adjustment is made using a screwdriver or hexagon. The choice will depend on the design of the design fittings.

You can determine by eye the degree of pressure on the window sash by how the tongue is located on it. The more it is extended, the higher the degree of pressure. If the hexagon is rotated counterclockwise, the sash forces will be reduced.

In cases where no option allows you to press the sash to the frame, you need to call a qualified specialist who can solve this problem faster.

Adjusting the hinges

In most cases, plastic window designs are not equipped with a window. The ventilation process can only be carried out after the sash is set to a certain mode.

Too large a gap between the sash and the frame in extreme cold will contribute to strong cooling in the room.

It is necessary to find a “golden mean” so that the gap during ventilation is somewhat smaller. Therefore, you can adjust the pressure of the window hinges so that there is no draft. First you need to determine the location of the blower. If this place is located near the bottom hinge, then a hexagon is needed. You need to remove the cap and start adjusting according to the instructions.

The sash must be set, the handle must be turned to ventilation mode and the top hinge must be pressed. When the window is closed, it is impossible to reach the screw responsible for the degree of clamping of the hinge.

Some window designs have special blockers that disable the ability to open the window. If the handle dangles, this will only make the problem worse.

You need to slightly lift the plastic plate located next to the base of the handle, and then rotate it 90 degrees. After this, the screws will be visible, which need to be tightened with a screwdriver until they stop.

If the handle does not turn well, then you need to lubricate the fittings with machine oil: eccentrics, hinges, clamping mechanisms.

You need to check the fittings and window structure at least once a year, even if nothing bothers you about its operation. Adjustment will allow you to quickly solve problems yourself.

Winter and summer mode

Plastic windows often need to be adjusted for the winter. It is in winter that complete sealing is necessary. In the summer you can let in some fresh air. This is achieved by adjusting the pressure density of the sash. Everything is done in an elementary way.

When adjusting the fittings, you should remember that the summer mode corresponds to a weak window closing pressure, and the winter mode corresponds to a strong or standard one. If work is carried out in winter, then first you should set the standard position and check whether there is airflow. On new PVC, you should not immediately pinch the rubber bands. In this position, the rubber seal installed around the perimeter is strongly pressed. Over time, this causes it to lose its elasticity.

If you immediately set the maximum pressure level, the rubber will deteriorate faster. As a result, the next time you set the plastic windows to the winter position, you will find the elastic all in cracks, and there will still be blowing from under the sash. This means that the seal needs to be replaced. This is not a very difficult process, but it will take more time.

Let's highlight the main requirements for PVC windows to last as long as possible at different times of the year:

• Do the adjustments yourself correctly so that you do not have to repair the plastic window.
• Insulation materials must be replaced promptly when worn out.
• In summer, loosen the pressure.
• In winter mode, the fittings should not be left for the whole year.

Cleaning the fittings from accumulated dust

Adjusting fittings and repairing plastic windows is associated with high-quality care of the structure. It is necessary to ensure deep cleansing in hard-to-reach places from accumulated dirt. If you don’t clean your windows in a timely manner, sooner or later you will have to repair them again because their functionality has been compromised due to debris. The process of repairing plastic windows is very labor-intensive due to the weight of the structure, so it is better to carry out this work with assistants.

To put the elements in order, use the following adjustment scheme:

• The sash is removed from its hinges, and the overhead frame elements are inserted.
• The top axle is removed.
• The sash is removed from the lower hinges.
• Carefully set it aside.

Then the area of ​​the sash is inspected and the screws attached to it are unscrewed. The parts of the mechanism should be well lubricated; it is advisable to use specialized solutions that are convenient to apply with a brush. After completing the procedure, the structure must be dried thoroughly using cold air from a hairdryer in the fresh air. Lubricant is applied to each driving mechanism, after which the fittings are assembled in the reverse order and then installed in their original place. Be sure to apply lubricant to each window hinge after adjusting the plastic windows.

It is technically easy to adjust a plastic window. It is enough to use detailed instructions and follow the recommendations themselves in strict order.

The process of adjusting window fittings on plastic windows may depend on the manufacturer. There are varieties that are adjusted with screwdrivers located on the side of the handles. They can be adjusted using a hex key.

Setting all positions for the adjustment points can be done even without experience. The only requirement is to be careful. If calibrated incorrectly, the plastic window may stop functioning correctly, after which you will have to call a technician to re-adjust it.
