How to glue vapor barrier sheets? Adhesive tapes, Adhesives and Sealing tapes for roofing and repair work, DELTA, TYVEK and others

The arrangement of waterproofing must be treated as responsibly as the choice roofing. Vapor barrier tape is a special construction tape used to seal the joints of vapor barrier films. If unsuitable or low-quality adhesive tape is used for these purposes, it peels off from the film, the seams lose their tightness, and moisture freely enters the insulation. As a result, the thermal insulation properties of housing construction are reduced or lost.

Types of adhesive tapes for connecting vapor barrier films

All special tapes used to connect vapor barrier films differ in their structure and differ in the materials from which they are made. Structurally, they are one- and two-sided. The first ones are used for attaching the butt-to-butt vapor barrier film strips to each other, and the second ones for attaching the overlapping vapor barrier.

Buy vapor barrier tape from various materials the following types are possible:

Aluminum tape is a layered building material consisting of protective paper, aluminum tape (20-40 microns thick) and an adhesive layer. This type of adhesive tape with a tape width of 5-10 cm holds vapor barrier films well, but it can not be used with all their varieties.
Reinforced tape with aluminum differs from the standard tape with an aluminum layer by increased strength due to the placement of a reinforcing layer inside it. Width 5-10 cm.
Polypropylene is the cheapest and most affordable type of tape. You can buy adhesive tape for vapor barrier in almost every hardware store. However, such a tape has a serious drawback - insufficient reliability of the seam for fastening vapor barrier films. Such adhesive tape is usually produced with a width of 5.0 cm, and a thickness of 20-100 microns.
TPL tape combines a polyethylene coating on the outside with a fabric backing and a rubber adhesive. For example, such adhesive tape is rarely used to seal the seams of the TechnoNIKOL vapor barrier. The thickness of the TPL tape is 200 microns, and the width is 5 cm.
Butyl rubber tape has good adhesion and adheres well to the vapor barrier surface. The width of this type of adhesive tape is 1.5-5.0 cm.

Mounting tapes Ondutis

Ondutis ML is a double-sided self-adhesive tape with a fabric backing. The artificial rubber included in its composition provides a stable and reliable connection for up to 15 years. Such adhesive tape, 5 cm wide, is used during the installation of vapor barrier films on walls, ceilings and the roof itself, it is non-toxic and safe. Ondutis ML is used as a sealing tape (universal) when placing films - roofing and vapor barrier, on the protective elements of buildings. It is used for hermetic connection (sticking) of seams of vapor barrier films.

Ondutis BL is a double-sided tape with a non-adhesive (anti-adhesive) paper backing. This tape provides a stable air and vapor tight connection for up to fifteen years. Sold in 2 rolls 25 meters long (each). This BL tape is used for sealing various connections to wooden, concrete, brick and other roof penetrations (eg pipes for various purposes, ventilation ducts), as well as for attaching films to brick or concrete walls.

Fixation of film vapor barrier building materials

The main tier of film vapor barrier is placed along the roofing cornice, in compliance with the sagging required during installation relative to the rafters at the level of 1-2 cm.

It is important to correctly form the space between the rafters so that it does not exceed 1.20 m.

In addition, it must be ensured that the size of the air gap between the heat-insulating elements and the waterproofing film is about 4 cm.

The placement of the waterproofing layer is carried out horizontally - from the cornice overhang to the ridge beam, with a mandatory overlap of 10-15 cm. The maximum value of the sagging of the waterproofing film in relation to the rafters is strictly observed and should not exceed 2 cm.

The edges of the insulation are overlapped, with the mandatory gluing of the seams with the appropriate adhesive tape, glue or tape.

The vapor barrier film over its entire surface is fixed with a stapler. Application for fastening of nails with a galvanized surface is allowed.

It is important that the hardware used for fastening be with a wide upper part that prevents damage to the insulation building material.

Each next piece of film is placed with an overlap of the previous one by 20 cm, and this value changes, depending on the value of the roof slope.

On top of the waterproofing coating, bars of the counter-lattice are placed. The minimum value of the cross section of the bars should be within 4 * 2.5 cm, with an interval of 10-15 cm. Then the installation of the crate structure is carried out.

In the upper part of the roof between the ridge beam and the waterproofing film, a gap of up to 5 cm is made.

In places where various pipes, masts or antennas are attached to the roof, film insulators are cut and glued to the nearest parts of the crate structure. For these purposes, either vapor barrier tape or self-adhesive (double-sided) tape is used. If the roof is placed skylights, to perform their waterproofing, you need to follow the recommendations of the manufacturers of such windows.

When laying a perforated film waterproofing, it is important to observe the correct placement of the vapor barrier side, laying the perforation on the outside. Otherwise, there is a possibility of moisture getting into the under-roof space and thermal insulation, accumulation of condensate and steam inside, which will lead to rotting of the roofing parts and the appearance of leaks.

How to choose and buy vapor barrier tape correctly

It is necessary to remember the basic rule - ordinary adhesive tape is not used for gluing the seams of vapor barrier films. Most of these insulating films have a rough outer surface, so the tape will lag behind it almost immediately after gluing. When choosing the type of adhesive tape, it is necessary to take into account its following characteristics:

resistance to ultraviolet radiation and various natural phenomena;
low moisture absorption rate (up to 0.2%);
operating temperature range (between −40 and +80С);
adhesion resistance with certain types of building materials (metals, wood, concrete, films)
long service life (up to 15 or more years).

Important: do not purchase adhesive tapes and tapes for gluing vapor barrier joints from unknown manufacturers. Such adhesive tapes may be unsafe for health and environment(often even toxic).

In addition, these adhesive tapes cannot guarantee the desired bonding quality. Best for vapor barriers Various types butyl rubber construction tapes.

To increase the reliability of the connection of vapor barrier sheets, the double gluing technique is used. First, the canvases are glued with each other “overlapped”, using double-sided adhesive tape, and then the resulting seam is reinforced, gluing it one-sided.

Installation of vapor barrier tape consists of the following steps:

Preparation of the glued surfaces of the films - they need to be cleaned, dried and be sure to degrease.
On the prepared basis, the lower web of the vapor barrier film is placed. Adhesive tape is glued around the perimeter of the entire canvas.
The protective film is removed from the top surface of the tape.
On the first sheet "overlapping" the second sheet is placed, and the place where the seam is formed is clamped as tightly as possible.
Then the edges are glued with adhesive tape.

Important: to ensure best quality connections, sealing of seams must be carried out at optimal temperatures and humidity.

What vapor barrier tape to buy and how not to make a mistake with the choice - video

Execution of construction, installation or repair work, associated with the use of sealing and fixing compounds. However, to perform such tasks, there are not only liquid or powder products, among the variety of products, specialized adhesive tape is also distinguished, most often used for vapor barrier of buildings and structures.

Features and purpose

Any construction of premises, especially residential buildings, is not complete without the use of vapor barrier raw materials. The presence of such materials, most often a vapor barrier film, makes it possible to provide good protection to the important components of the entire structure from the penetration of moisture, which has a devastating effect on most surfaces.

In addition, the presence of a membrane will eliminate the risk of condensate entering the room, which will protect it from the formation of fungus and mold on the grounds.

Mistakes made during the installation of materials for vapor barrier will lead to the accumulation of excess moisture in an apartment or house, as a result of which the raw materials for insulation will lose their qualities, over time, ceilings on the ceiling and walls will collapse. That is why competent styling, as well as gluing vapor barrier material is an important task for the construction and durability of a residential structure.

When arranging roofing cake buildings, vapor barrier tape is a fundamental element that provides the necessary waterproofing barrier, together with the main roofing materials. Usually, bituminous tape is used for roof waterproofing, which looks very similar to construction tape.

Window structures, the installation of which is mandatory during the construction of buildings for any purpose, requires reliable protection of the joints of the frame with the wall. Therefore, in addition to the traditional polyurethane foam, you will need to glue the corners and joints of windows with a reliable sealing material, which is represented on the building materials market with construction tape.

The product is a special-purpose tape designed for gluing different elements together. A feature of adhesive tape should be considered its ability to provide reliable insulation of joints and seams from the penetration of moisture and steam. It should be noted that the use of ordinary stationery tape for the above works is not justified, since the product will gradually peel off after a while, passing moisture through the gaps formed, which destroys the layers of heat-insulating material.

Characteristic

Vapor barrier tape is a construction tape of various sizes and structures, the scope of which is to provide good sealing of the joints of vapor barrier products. In fact, it is an adhesive tape for vapor and waterproofing, which is a new product on the modern market for goods for construction and repair. But due to its properties and characteristics, such adhesive products have already become popular and in demand among consumers.

This demand for the product is explained by the low quality of the insulation of joints and seams, which is carried out in buildings built not so long ago. For new settlers, whose dwelling is adjacent to the attic, this issue is especially relevant, since poor-quality vapor barrier, over time, negatively affects the microclimate in the apartment. In addition, the tightness provided by the vapor barrier tape makes it possible to prevent the rapid exit of warm air from the apartment and the penetration of cold air masses from the street.

Based on the characteristics of the connecting tape, it can be used to fix and seal the joints of the film, located in the horizontal and vertical direction. Adhesive tape is glued to the very edge of the base, be sure to place the adhesive paper on top. After that, another film sheet is laid overlapping with fixation with a tape, pressing all joints.

To ensure high-quality sealing at the junctions of materials with constituent parts, installation of adhesive tape must be carried out on a solid base, such as metal, concrete or brick.

Double-sided mounting products can also be attached to the material itself. To accomplish this task, it is necessary to remove the adhesive paper from the surface, and then, having placed the entire roll with tape in a given direction, roll it out over the base, pressing down a little in the direction of travel.

In this case, a certain distance recedes from the edge of the cloth.

The tape should only be used to seal the joints between materials, their fixation to the work surface during the laying process is carried out using fasteners, most often nails are purchased for such work or fastening is done using a construction stapler.

The adhesive tape for vapor barrier has the following characteristics:

UV resistance;
low moisture absorption rate of 0.2%;
resistance to atmospheric phenomena;
the product does not lose its properties in the temperature range from +75 C to -40 C;
high level adhesion to a concrete surface, metal, film, wooden bases;
operating life is about 15 years.

Kinds

Without exception, all vapor barrier tapes have an adhesive base, this feature eliminates the need to apply the adhesive on their own, thereby reducing the risk of poor-quality fastening of products, which will entail moisture ingress onto the thermal insulation.

The classification of products is based on the raw materials used for the production of the tape, as well as the structure of the product.

According to the structure, construction adhesive tape for vapor barrier can be double-sided and one-sided. The latter type of product is used for fixing materials end-to-end. Products of the first type carry out overlapping of the canvases.

Taking into account the raw materials from which the tapes are produced, the products are divided into the following varieties:

Aluminum scotch- it is a kind of composition, which includes an aluminum tape, the thickness of which can vary from 20 to 40 microns, as well as an adhesive and a protective base. Products have positive reviews, however, the disadvantage of such a tape is the fact that it can not be used for all types of vapor barrier films. Aluminum tape usually has a width of 50 to 100 mm.
Reinforced aluminum products- such products are characterized by greater strength, in contrast to the previous type of adhesive tape. This characteristic is due to the presence of a reinforcing reinforcing layer in the composition of the product. The adhesive tape has a width of 50–100 mm.
Polypropylene Tape- products have a low cost and are sold in any construction department. In this case, the statement of the relatively poor quality of cheaper analogues is completely justified, since experts note unreliable fixation when working with such material and vapor barrier films. Typically, the width of polypropylene tape does not exceed 50 mm, with a thickness of up to 100 microns.

Scotch TPL - is a textile-based product with a rubber-based adhesive and a polyethylene surface on the top side. Rubber self-adhesive products, for the installation of vapor barrier is used infrequently. It has an impressive thickness - about 200 microns, with a width of 50 mm.
Butyl rubber tape- the product stands out for its advantage - butyl tape has a high level of adhesion to vapor barrier materials. The disadvantages of the product include a large specific gravity tape, which exceeds the same value of aluminum tape five times. The width of the product varies between 15-50 mm.

It should be noted that rubber tapes are used most often for windows, balconies and door structures. In rooms with high humidity, metal-based products are used.

In addition, tapes are classified based on the climatic purpose:

for operation at negative temperatures, “winter” products are produced that do not lose their properties from exposure to frost;
films of the "summer" type are recommended for use at medium positive temperatures.

Dimensions

The dimensional grid of products on the market is as follows:

products with a length of 25000 mm, having a width of 15 mm, 30 mm, 50 mm, 60 mm, 75 mm;
30,000 mm long options with 15 mm and 60 mm tape widths;
products with a length of 23000 mm and a width of 152 mm.

How to choose?

To do right choice adhesive tape for vapor barrier, it is necessary to pay attention to the following characteristics of the presented product:

Sealing tape can be used in specific places in residential buildings and structures, so the resistance of the product to ultraviolet radiation is a fundamental criterion when purchasing a particular product.
Adhesive tape should not absorb water, otherwise there is a risk of spoiling the heat-insulating and vapor barrier material.
Products High Quality must be heat resistant up to 90 C.
Tape adhesion to various surfaces. There are some types of products that are incapable of adhesion to metal bases.
As a rule, the average life of vapor barrier tape is about 15 years. However, each manufacturer may vary.

When buying a tape, it is worth clarifying this information.

The technology of working with adhesive tape requires compliance with certain rules.

Any manipulations with the tape can be performed only on cleaned and completely dry surfaces.
Next, a vapor barrier sealing sheet is laid out, which is glued with tape over the entire width and length.
After that it is removed upper layer adhesive tape.
The final step is the laying of the second layer of insulation, which is glued to the product located underneath.

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 building 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 some places after a day. 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.

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 insulation matters.

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 it can be judged by the characteristics of adhesive tapes, each of them is good in its own way and the scope of its application 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 insulated surfaces are not properly prepared.

I strongly advise you not to rely on the Russian "maybe", but with all responsibility to approach the issue of choosing adhesive tape for vapor barrier, 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.

The installation of a vapor barrier layer is mandatory when building a dwelling. The film serves to protect the insulation from the vaporous liquid that comes from the room into the inside of the roof of the house. The vapor barrier membrane prevents the penetration of condensate (the transition of a substance from a vapor to a liquid state) into the living room.

If the vapor barrier is installed on the wrong side, the house will accumulate too much vapor. The penetration of moisture under the roof will not be controlled. The insulation will absorb a large amount of water over time and lose its thermal insulation characteristics, and gradually the wall or ceiling coverings will be destroyed. This article will consider the issue of gluing vapor barrier sheets.

Since the sealing of the joints of the vapor barrier layer occurs with the help of special construction tape, this material will be discussed. Will also be considered general rules and the nuances of establishing a vapor barrier.

Vapor barrier tape is a bonding tape that will help to seal vapor or water tight coatings or areas where certain parts fit together. If you use ordinary adhesive tape, this will lead to its quick peeling off, and moisture will freely enter the heat-insulating layer.

Vapor barrier tape is divided into several types:

Connecting tape made of aluminium. The thickness averages thirty micrometers. This type copes with the task perfectly, but it is not suitable for all types of vapor barrier. The width of the aluminum tape is approximately ten centimeters;
Reinforced tape. This construction connecting tape differs from the previous one in great strength, the width is about the same;
Polypropylene construction tape. The main advantage of the material is its low cost in the construction market. However, this adhesive tape is rarely used when gluing vapor barrier sheets, since it has low strength;
Universal reinforced adhesive tape. The basis of this type of tape is fabric. And the base of the glue is rubber. Very rarely used for vapor tightness. Tape width - five centimeters;
Butyl rubber joint tape. The type has excellent adhesion to the surface and adheres well to the vapor barrier layer.

Ordinary clerical connecting tape is not suitable for gluing vapor barrier sheets. Literally after a short period of time (one or two days) everything will peel off.

When buying a special construction adhesive tape, the following characteristics should be considered:

this material must have high resistance to ultraviolet rays;
adhesive tape should practically not absorb moisture;
the ability to withstand temperatures up to 90 degrees Celsius;
construction bonding tape must have excellent adhesion to wood and metal surfaces(adhesion);
service life - fifteen years.

It is not recommended to purchase a connecting tape from an unknown company at the construction market or store. The material from which the adhesive tape can be made is capable of releasing toxins, which can be harmful to the human body. Also, there is no guarantee of quality.

The vapor barrier web should be glued first with double-sided tape, and then the second layer with one-sided tape.

While working with special tape, you must follow a certain algorithm of actions:

first you need to clean the surface of dust and other dirt, and then dry it;
the most bottom layer vapor barrier, it is sealed with a special connecting tape along the entire length and width;
then we get rid of the film from the top of the adhesive tape;
at the end, the second layer is installed, it must be pressed tightly and sealed.

Vapor barrier installation

There are materials specifically designed to establish a vapor barrier with a single layer of film, polyethylene, or materials with two layers. All of them are different from each other, so the question arises: “which side to glue the vapor barrier layer?”.

BOPP (Polypropylene Biaxially Oriented Film) is glued with the rough side to the underlayment. If the installation is done correctly, then the accumulated moisture will be able to go into the vent without any obstacles.

The membrane with two layers is glued with a smooth surface to the heat-insulating layer. Often, the manufacturer will even make a note on the correct side of the membrane. This greatly simplifies the work.

Polypropylene with a one-sided laminated coating, as well as the previous material, is glued with a smooth surface.

Of course everything Construction Materials, intended for installing a vapor barrier, differ from each other, so it is best to read the proposed instructions, or consult with the seller of the hardware store.

It should be remembered:

if the membrane is painted in different colors, it must be glued to the insulation with a lighter side;
usually the desired side of the film, which needs to be glued to the surface of the vapor barrier layer, is the inner side.

Main stages of work

When installing a vapor barrier layer, there is a specific algorithm of actions. This layer is placed after thermal insulation. The insulation must not have any cracks or other defects. Construction bars for crates are treated with chemical antifungal agents. The film must coincide with the entire perimeter of the surface.

For work you will need:

pencil;
construction stapler;
screws;
screwdriver (an ordinary screwdriver will do);
tape measure;
scissors;
construction knife;
one-sided tape (required for connecting various joints), as well as double-sided tape (needed for gluing vapor barrier sheets).

Step by step installation:

In carrier system pitched roof(rafters), where the heat-insulating layer is located, it is necessary to fill the lower part of the coating, consisting of purlins, with two boards. With construction special adhesive tape, it is necessary to make a strip that will be adhesive on both sides. Then you need to cut the roll of the required length. From the bottom of the covering of purlins, the film should be glued onto the insulation on the side where the mark is located.
It is important to glue the ends of the vapor barrier sheets to the supporting system of the pitched roof. This connection is made using a construction stapler. The bottom of the membrane is glued to the crate. Stepping back twenty centimeters from the top, you need to stick the next strip, while not tearing off the previous layer, intended for protection.
Following this algorithm, it is necessary to glue the appropriate number of rows. The sealed film should be fixed with bars. The bars can be fixed with screws. Remember to leave a vent hole between the ridge and the roof eaves.

Throughout the work, it is necessary to monitor the integrity of the structure. If any vapor barrier sheet has been damaged, it must be urgently replaced with another one.

Features of installing a vapor barrier

Installation of vapor barrier on the walls of the room occurs if only the insulation has a mineral base, and the outer side is on the street.

To properly install the vapor barrier layer, you must:

with the right side, carefully fix it on the covering, consisting of purlins, because the surface can be damaged;
it is important to carefully close everything possible defects surfaces (slots, holes, etc.);
it is necessary to carry out the installation of the crate with the help of bars to create ventilation;
the overall structure can be covered with decorative wall panels.

To date, there are many films to create a vapor barrier. But the best membrane is Ondutis. This material is excellent for protecting the heat-insulating layer and the roof from the destructive effects of condensate.

The main advantage of Ondutis is that it is suitable for absolutely any structure (walls, ceiling, floors, roofs and other places). Membrane Ondutis is a polymer sheet gray color. This material is especially valuable in winter period time. Ondutis is the protection of your premises from wind, moisture and steam.

Conclusion

As you could learn from this article, gluing vapor barrier sheets requires you to have some care and accuracy. The main construction tool is a special adhesive tape. It is necessary to fasten the film with the side where the marking is located (but do not forget to read the instructions before buying).

Before installing the vapor barrier layer, the surface must be prepared by first cleaning it of dust and dirt, and also by treating it with chemical antifungal agents. The vapor barrier is installed in several layers. During operation, do not forget to leave holes for the release of vaporous liquid.

At the time of buying additional materials you don't have to feel sorry for yourself Money, because in the future the comfort and coziness in your home depends on it. Also an excellent material is glue for vapor barrier. The whole procedure can be carried out on your own, but it is better to trust professionals, because the work is quite complicated and takes a long time. Experts will make installation qualitatively, and you should not think of any problems.
