Is it possible to glue the joints of the vapor barrier with ordinary adhesive tape? Adhesive tapes, Adhesives and Sealing tapes for roofing and repair work, DELTA, TYVEK and others Adhesive tape for attaching vapor barrier.

In our article today, we will talk about protecting the insulation from steam penetration. To be quite precise, we will try to find out the better to glue the vapor barrier. What are the means for this, and how they are used in a particular case. To help understand all the nuances and subtleties of the issue, we asked an expert in matters of insulation.

Editor:

Good afternoon Specialist! A lot of words have been said about the thermal insulation of residential premises, attics, balconies, attics. We have clarified the situation regarding the need to use a vapor barrier material in certain cases. But how to properly connect the vapor barrier sheets, how to seal the joints - these questions were left "overboard". Let's help readers figure it out.

Specialist:

Bonding sheets of vapor barrier material is a fairly simple process. But, at the same time, very responsible. There are several types of adhesive tapes, and first of all, let's define the basic requirements that they all must meet:

  • High adhesion of the adhesive layer - the canvas must be reliably, “tightly” glued both to the insulated structures and to the surface of the vapor barrier sheets;
  • Should not break down or change its properties under the influence of ultraviolet radiation;
  • Should not absorb moisture;
  • The operating temperature range should reach up to 90 degrees Celsius;
  • The service life of the adhesive tape cannot be less than the service life of the steam insulation itself - and this is an average of 15 years.

Editor:

Our readers asked the question: "Is it possible to use ordinary stationery tape to connect the joints?"

Specialist:

My answer is definitely no. For all its stickiness and moisture resistance, it falls behind in just a few days. Here are those connecting materials that will cope with the functions assigned to them:

  • Aluminum tape. This is a ten-centimeter wide roll of special aluminum foil with an adhesive layer. Perhaps this is the most versatile connector, but it also copes with sizing far from all types of vapor barrier.
  • Reinforced tape. In fact, this is the same aluminum connector, but with increased strength.
  • Polypropylene adhesive tape is perhaps the most budget-friendly connector. But it has the lowest strength, which leads to its infrequent use.
  • Adhesive universal adhesive tape reinforced. A five-centimeter wide roll of adhesive tape is reinforced with a fabric layer, and the adhesive composition is based on rubber resin.
  • Butyl rubber connecting tape. High adhesion and reliable bonding - this is exactly what is the advantage of this connector.

Editor:

As far as can be judged by the characteristics of adhesive tapes, each of them is good in its own way and its scope is determined by the characteristics of the premises, structures and types of surfaces that we glue?

Quite right. In addition, I want to draw attention to the fact that even the strongest adhesive composition will not cope with its task if the surfaces to be insulated are not properly prepared.

I strongly advise you not to rely on the Russian “maybe”, but to approach the issue of choosing adhesive tape for vapor barrier with all responsibility, because the reliability and durability of the thermal insulation of the entire building or your premises separately depends on such a seemingly trifle. The joint that has opened due to the peeled off tape will become a channel for the penetration of moisture into the insulation fiber. Deterioration of thermal insulation, dampness, fungus ... Having saved on trifles, we risk losing the battle for saving heat.

Adhesive tape ML is a double-sided self-adhesive tape on a fabric basis made of synthetic rubber. It has good adhesion and long term service, and also guarantees a reliable vapor-air-tight connection.

DELTA FLEXX-BAND F100

DELTA FLEXX-BAND F100 is an elastic one-sided bituminous rubber tape with adhesive, with high adhesion on a high-strength tape made of nonwoven fabric, for sealing elements passing through the roof.

Tape DELTA INSIDE-BAND I 60

Tape-adhesive DELTA INSIDE-BAND I 60 Universal single-sided tape with high adhesion for hermetic bonding of vapor barrier films in the overlap zone on the front side. Can be used to bond films to metal, hard plastics, smooth wood.

The best tapes and adhesive tapes for vapor-waterproofing

The main purpose of adhesive tapes and tapes for vapor barrier, waterproofing is a tight connection of films in places of overlap. This creates a sealed vapor barrier between the vapor barrier and walls, ventilation pipes passing through the roof, various junctions, fixing to the Mauerlat or any other roof structures.

Double-sided adhesive tapes, tapes for various membranes, as a rule, guarantee the quality of work carried out with vapor barrier and waterproofing. It is also necessary to think over the connection of the counter-lattice with the films; for this, a special sealing tape is provided, which ensures a tight connection at the places of nail fastenings.

Often the roofing film is fixed with a mounting stapler and this is where it all ends, but on a roof with a small slope this is a gross violation that will lead to the leakage of vapors and condensate. You can buy double-sided tape or vapor barrier tape at any roofing store or order it through an online store, which will completely create a high-quality vapor barrier.

The price of adhesive tapes and sealing tapes

The price of adhesive tapes is different, it differs from each other by manufacturers, as well as the width of the roll and the length. Adhesive tapes, tapes create an excellent vapor-tight seal of the vapor barrier overlap, hydro-wind protection to create a durable roofing pie structure. These are inexpensive roofing accessories that are not worth saving on. We have collected for you the best and most trusted manufacturers of sealing tapes and tapes sealing the hydro-vapor barrier joint.

I have long dreamed of building an attic in an empty attic. And this summer, finally, the dream began to come true - construction began. It seemed that he had foreseen everything: he studied the construction technology, prepared the necessary construction material. The problem arose unexpectedly for me where I least expected it - in the choice of adhesive tape for vapor barrier.

On the advice of knowledgeable craftsmen, I was looking for butyl rubber tape, but even in large building supermarkets they could not offer anything worthwhile from this series. I had to use a gray rubber-based reinforced tape. Since the first time it was difficult to decide on the footage of the tape, during the construction of the attic I had to buy additional adhesive tape several times. At the same time, each time there was a similar adhesive tape in stores, but from different manufacturers. Thus, adhesive tapes Klebebander TPL, Unibob, Super Tape Moment were used.

It is no secret that the success of the whole business depends on the quality of the work performed on the vapor barrier of the insulation. And here it was very important to seal the joints of the vapor barrier film with high quality. Vapor barrier tape must adhere securely to the film and not fall off over time.

By the way, Isospan-V film was used as a vapor barrier material. Film on appearance similar to the material from which granulated sugar is made.

I tried to glue these adhesive tapes on a cheaper vapor barrier film, similar to spunbond for gardeners. The outer surface of such a film is fleecy, and any of these films adheres to it very weakly and peels off in separate places a day later. Therefore, I want to give a comparative assessment of the adhesive properties of adhesive tape on the Isospan-V vapor barrier film.

Adhesive tape Klebebander TPL

Gray reinforced polyethylene tape with a rubber-based adhesive. Unlike other tapes - thin. It is convenient to work with her. It unwinds easily and sticks firmly to the vapor barrier film. After a few days, I did not notice its peeling off at the joints of the vapor barrier sheets.

Adhesive tape Unibob

Its composition is similar to the previous film, but it is thicker. The film was bought twice - the first time I got a film with a smooth surface, and when I bought it again, I noticed longitudinal stripes on the surface of the tape. In terms of the quality of the adhesive layer, it was inferior to the Klebebander TPL tape. After a few days, I began to notice that in some places the tape had slightly moved away from the vapor barrier film.

Adhesive tape Super Moment

The gray reinforced tape is outwardly similar to the previous grades. When purchasing this tape, I bought into the word Super, although later I did not notice anything super in it. In terms of quality, it is inferior to the above-mentioned tapes. A few days later, in some places, it began to peel off, and for safety, the most problematic areas had to be additionally glued with Klebebander TPL tape.

Thus, from a forced experiment, I concluded that it is not worth saving on adhesive tape for vapor barrier. Otherwise, in the foreseeable future, big problems will arise, the solution of which will lead to considerable financial costs.

To ensure reliable protection of the roof from moisture and steam, it is necessary to responsibly approach the installation of the roofing pie, select the necessary waterproofing components, including glue, adhesive tape or tape for vapor barrier and some other components. The completed protection must fully meet all the stated requirements. It is recommended to approach its implementation no less responsibly than the selection of roofing coverings. Installation plays an important role vapor barrier films and waterproofing membranes, which will be discussed below.

Fixation of film materials

The main tier of the film is laid along the entire roof eaves, with the necessary sagging relative to the rafters at the level of 10-20 mm. Experts advise creating a space between adjacent rafters no more than 120cm. It should be noted that the height of the air gap of the heat-insulating components and the waterproofing film should be about 40mm.

The waterproofing itself is laid in a horizontal direction, starting from the eaves and reaching the ridge, observing an overlap of 100..150mm. The maximum sagging of the film relative to the rafters should be no more than 20mm. The edges of the insulation are joined with an overlap, with the obligatory gluing of the joints with the appropriate tape, adhesive tape or glue.

On the entire working surface, the vapor barrier film is fixed with a construction stapler. Use of galvanized nails is allowed. It is important that the hardware has a wide cap, which will not damage the material.

Each subsequent row of film material is laid with an overlap of up to 200 mm, and this value fluctuates depending on the size of the roof slope.

On top of the waterproofing, bars of the counter-lattice are installed, while their minimum cross section must be at least 40 * 25mm, with an interval of 100-150mm. Next is the installation of the crate.

In the ridge part of the roof, a gap of up to 50 mm is guaranteed between the corresponding axis and the waterproofing film. It is necessary to perform a ridge vent, which is a break in the insulating component under the corresponding part of the roof, which ensures ventilation of the hidden space.

In the area of ​​​​fixation to the roof of various masts, a chimney or an antenna, usually film materials are cut and glued to nearby elements of the crate. For this purpose, either adhesive tape for vapor barrier or double-sided self-adhesive tape is used. In the case of skylights, when providing waterproofing, it is recommended to follow the instructions of the manufacturers.

When working with perforated film, observe correct location sides of the vapor barrier with perforations oriented to the outside. In another version, there is a high probability of moisture passing inside the roof, the formation of steam inside, which will lead to the opposite effect. Very soon rot and roof leaks will be discovered.

How is the anti-condensation film installed?

The sequence of actions is as follows:

  • 1. Upon completion of the installation of rafters and insulation, the film is fixed. It is best to wait for dry weather for this.
  • 2. The maximum rafter distance should be within 120cm.
  • 3. The anti-condensation film is unfolded in one position, when its surface is facing the absorbent part to the bottom. The corresponding base is positioned so as not to touch the insulation elements.
  • 4. Fixation is provided by staples of a construction stapler, glue, or galvanized nails with a large hat.
  • 5. Laying is carried out sequentially, starting from the cornice and reaching the ridge, with overlapping, in separate horizontal layers. The value of this overlay in the horizontal plane is up to 150mm, in the vertical part from 200mm.
  • 6. The joints of the film are displayed on the rafter parts of the structure.
  • 7. The joints are fastened with a special adhesive tape for vapor barrier or tape for waterproofing.
  • 8. Be sure to place the film evenly, without any hitches. The formation of a sag of up to 20 mm is allowed in the central part of the space between the rafters, due to which the removal of steam and condensate from the wooden components is guaranteed.
  • 9. The maximum distance relative to the insulation and the film is recommended to be in the range of 40..60mm.
  • 10. When installing, you should understand that Bottom part waterproofing is designed to drain water into the corresponding gutter.
  • 11. At the end of the work, the installed coating is fixed by means of wooden slats with a section of 30 * 50 mm with galvanized hardware. Roof framing is placed on top.

Features of installing a waterproofing film

Here are the main points to pay attention to:

  • 1. It is unacceptable to install the film in such a way that during its operation moisture from the upper part gets on the insulating layer of insulation.
  • 2. It is important to process the junction of penetrating elements with high quality, whether it be chimneys, antennas, ventilation ducts and more. To this end, trapezoidal cuts are provided at certain points. The valve of the upper and lower location is fixed to the horizontal component of the crate with a sealed tape, or to a penetrating element. The elements of the side execution are retracted to the upper point and fixed to the penetrating component in a similar way.
  • 3. In the case of skylights, follow the manufacturer's instructions for quality installation of adjacent materials.
  • 4. Roofs with sloping ridges and hipped roofs require that the foil be laid in relation to the longitudinal axis of the respective element.
  • 5. Stripes with horizontal arrangement on the pitched part of the roof, they are mounted outside with an overlap.

Installation of superdiffusion and diffusion membranes

With the help of these components, ideal protection of the home from moisture is ensured, since their vapor-permeable qualities are much higher than other materials. The membranes with the maximum working parameter are placed directly on the insulation, without the need to provide a lower space.

In most cases, they are limited to an upper ventilation gap within 40 mm, relative to the crate and the membrane itself. Laying is carried out in a horizontal direction, from the bottom of the roof to the ridge part.

Fixing the membrane to the rafters is carried out using a construction stapler, galvanized nails with a wide head or glue for vapor barrier, with fasteners with a counter rail. In the case of laying thermal insulation directly to the ridge, the membrane overlaps by 200 mm.

Having treated the crate with an antiseptic and other protective compounds, before starting work, you should make sure that the wooden elements are completely dry. At the end of the installation of the film, counter rails are mounted on the crate, otherwise steam removal is not guaranteed.

All subsequent installation steps are similar to those with a waterproofing film, where galvanized hardware with a wide head, glue, or stapler staples are used to fix the membrane.

The membranes are joined with adhesive tape for vapor barrier, which protects against the effect of moisture capillary where the overlap is made. Areas where the roof intersects with penetrating structural elements, including chimneys, antenna racks and ventilation ducts, are subject to insulation. For these purposes, a sealing tape is used. Relatively skylights- follow the instructions of their manufacturer.

When choosing a type of membrane, you should always read the instructions for its application and operation in order to select the correct working side.

Installation of a diffusion membrane of volumetric design

We give the following sequence of actions:

  • 1. Laying is carried out parallel to the overhang of the cornice, with placement on a solid part of the flooring.
  • 2. Fixation along the upper edge is carried out using roofing nails or stapler staples.
  • 3. Each regular roll is installed with an overlap of the fixing point by 70mm.
  • 4. The overlap is treated with glue or an appropriate compound
  • 5. A sealing tape on a self-adhesive basis, often made of polyurethane foam, is fixed on top of the waterproofing film. This guarantees the necessary protection in the installation area of ​​the counter batten using nails.
  • 6. It is allowed to work at air temperature up to -5 degrees.

Laying roofing films and membranes


Vapor barrier tape is used to secure vapor barrier joints. Vapor barrier tape or vapor barrier glue can also be used.

How to glue the vapor barrier film on the roof?

The technology of laying the vapor barrier layer provides for gluing the sheets together. In modern construction, special adhesive tape is used for these purposes. If you choose a simple stationery material, then there is a threat of moisture getting into the insulation. Since there is a large amount of adhesive tape in stores, let's figure out how to glue the vapor barrier.

The importance of sealing joints

The vapor barrier film is laid with inside rooms under thermal insulation. Its task is to protect thermal insulation from moisture from residential premises. The film itself does an excellent job, but vapors can enter through the joints of the sheets. To do this, each joint is isolated with a special adhesive tape.

If the joints are not sealed, moisture will penetrate to the insulation, due to which it will begin to lose its insulating properties. Wet mineral wool protects against cold 60% worse than dry.

In addition, when gluing the vapor barrier in the house itself, a comfortable humidity and microclimate are maintained. This is because the insulation absorbs vapor from the air and makes it drier. Due to the lack of water, problems with the health of the skin and respiratory tract can begin.

It is necessary to glue the joints of the vapor barrier layer during the new construction of a house or overhaul roofs. It is also recommended to check the quality of the roofing cake when buying a house, whether it is an old or modern building. Adhesive tape may peel off over time due to old age or due to poor quality installation work. In such a situation, you have to take on repairs, and here it is important to choose the right type of adhesive tape and the manufacturer.

Varieties of adhesive tape

Construction tapes have two factors by which they can be distinguished. First, there are different structural solutions. They produce one-sided adhesive tape, for gluing the vapor barrier end-to-end, and two-sided - for mounting overlapping cloths. Secondly, there is a wide variety in materials than to glue the film from which the docking tapes are made:

  1. Aluminum. Adhesive tape 50-100 mm wide, consisting of a layer of aluminum, protective paper and glue. The thickness of the metal in the film is not more than 40 microns, but it gives sufficient strength for work. This option is not suitable for all types of vapor barrier.
  2. Reinforced aluminium. It adds a reinforcing layer that increases the strength of the material. The width remains the same as in the previous version.
  3. Polypropylene. Most a budget option for gluing, which can be found in any store. Usually the width does not exceed 50 mm, and the thickness is 100 microns. Not recommended for use in construction due to high peeling potential.
  4. PTL tape. It consists of several layers: polyethylene film on the outside, fabric in the center and rubber-based adhesive on the working side. Quite a rare adhesive tape 200 microns thick.
  5. Butyl rubber. Most suitable option for connecting vapor barrier material to each other. Suitable for most materials. Has a width of 15 to 50 mm.

Adhesive tape brands

In order to choose the appropriate option, it is not enough to know only the technical characteristics or the material of the adhesive tape. Coming to the store, you already need to know the brand of adhesive tape and call it to the manager. Below we will analyze some popular options, based on this information, you can decide exactly what is right for your tasks.

Izospan SL

This tape is used simultaneously to seal the joints of hydro and vapor barrier. It was designed to seal the joints of protective films to structures passing through the attic roof pie. For example, it is used near chimneys, pipes and ventilation ducts or skylights.

In addition, its working surface is perfectly glued to the walls and provides a reliable, tight connection. Therefore, Izospan SL tape is used to process the edges of the vapor barrier layer in the attic.

Concerning specifications, then here the most important information regarding bond strength. If we talk about the connection with concrete, then the tear strength is 0.1 MPa. But gluing to metal surfaces is not recommended, since adhesion decreases tenfold.

The water absorption of adhesive tape is 0.2%, which is an excellent result when compared with roofing felt, in which the indicator fluctuates within 2%. The operating temperature is between -60 and + 140 °C. This tape is suitable for use in any area.

Izospan SL belongs to the group of double-sided adhesive tapes, therefore it is only suitable for overlapping vapor barrier installation. To do this, adhesive tape is glued to the edge of the first roll, then the release paper is removed and the second roll is applied.

TechnoNIKOL

This adhesive tape has working surfaces on both sides. The basis for the tape is polypropylene, but despite this, the material performs its functions perfectly. The length of one roll is 25 meters, and the width is 3.8 cm. Due to the low cost, about $ 3 per piece, you can save on insulation without losing quality.

TechnoNIKOL adhesive tape is intended only for gluing vapor barrier rolls. It cannot be used for sealing the adjunctions of the film to the supporting structures. Most often it is used in residential private construction and industrial buildings.

Ondutis ML and BL

The mounting tape is designed for a service life of up to 15 years. Depending on the marking, the scope, surfaces to which adhesive tape can be glued differ. So, ML is a tape with an adhesive on both sides of the fabric base. Synthetic rubber, which is durable and reliable, acts as a connecting compound. It is produced in rolls 50 mm wide and 25 meters long. Designed for gluing vapor barrier in roofing pies and walls.

Ondutis BL also has two adhesive sides, one of which is covered with non-sticky paper. Used to seal vapor barrier joints with solid surfaces. They process connections with brick, concrete and wooden walls. In addition, it can be used as a film attachment to concrete walls.

A more expensive version of vapor barrier tape, which has an aluminum base and two adhesive surfaces. The tape has several color options and is available in rolls 10 meters long and 100 mm thick. The cost of this option is $ 11, which is explained by the scope.

Nicoband mounting tape is used to seal external seams. It is able to firmly bond the insulation film to plaster, wood, metal, roofing and concrete. The manufacturer gives a 10-year guarantee for tight connections.

Adhesive tape selection criteria

Remember that stationery tape is definitely not suitable for gluing a vapor barrier film. It is not designed for a strong connection with rough surfaces, so it falls off after a few hours. Even if it seems that it is firmly stuck, keep in mind that the manufacturer did not count on the operation of his adhesive tape in frosty conditions.

When choosing a mounting tape, pay attention to the following factors:

  • if you plan to use it outdoors, then the adhesive tape must withstand ultraviolet radiation and precipitation;
  • the level of water absorption should not exceed 0.2%;
  • it is important that the operating temperature coincides with the climatic zone;
  • choose tape for specific jobs, either for sealing the film or for bonding to hard surfaces;
  • minimum service life of 10 years.

Sealing joints and what is the best way to glue the vapor barrier? Types and brands of adhesive tape. Selection criteria and characteristics.

Tape for vapor barrier

Vapor barrier tape is a special construction tape that is used to seal the seams of vapor barrier films. Using the wrong adhesive tape leads to its peeling off and moisture ingress into the insulation. As a result, the house loses its thermal insulation properties.

In this article, we will consider the main types of adhesive tape for vapor barrier, we will help you make right choice and tell you about the nuances of installation.

Types of tapes for vapor barrier

All construction tapes can be divided according to structure and material. The structure is: single-sided and double-sided tape. The first is used for fastening the sheets "butt-to-butt", the second - "overlap".

According to the type of material, adhesive tapes are of the following type:

Mounting tapes Ondutis ML and BL

Ondutis ML is a double-sided self-adhesive fabric-based tape. Synthetic rubber, which is part of Ondutis ML, provides a reliable connection for 15 years. Adhesive tape is used for mounting vapor barrier on ceilings, roofs and walls. Standard width - 50mm. Harmless and non-toxic.

Ondutis ML is used as a universal mounting and sealing tape when installing vapor barrier and roofing films on building envelopes. It is used for hermetic gluing of joints of vapor barrier films on walls, roofs and ceilings.

Ondutis BL is a double-sided self-adhesive mounting tape on anti-adhesive (non-sticky) paper. The tape provides a reliable vapor-air-tight connection for 15 years. One package contains two rolls of 25 m.

Ondutis BL is used for sealing joints to solid surfaces (concrete, brick, wood) and roof penetrations (chimneys, ventilation ducts, etc.), as well as for attaching films to brick and concrete walls during installation.

How to choose and buy the right vapor barrier tape

The main rule to remember is that ordinary stationery tape is not suitable for gluing vapor barrier sheets. Because of the roughness outside film, it will fall off literally the next day. When choosing adhesive tape, the following properties should be considered:

  • resistance to ultraviolet and atmospheric phenomena;
  • low level of moisture absorption (0-0.2%);
  • operating temperature (ranges from -40 to + 75-80 ⁰С);
  • adhesion to a certain group of materials (film, metal, wood, concrete, etc.)
  • service life (15 years or more).

It is not recommended to buy products from unknown manufacturers. Firstly, they can be toxic, and secondly, no one guarantees the quality of bonding. Butyl rubber varieties of construction tapes are better suited for vapor barrier.

Installation of adhesive tape for vapor barrier

Tape installation steps:

  1. Preliminary preparation of all surfaces (cloths, bases). They must be cleaned, degreased and dried.
  2. The bottom layer of vapor barrier is laid on the base. Adhesive tape is fixed around the perimeter.
  3. The film is removed from the top of the tape.

  • The second "overlap" is laid on the first canvas and pressed tightly.

For best quality, sealing joints should be carried out at minimum humidity and room temperature.
