Vapor barrier tape for plastic windows - where to use and how to glue? Using tape to insulate windows Window tape for PVC windows

Any window needs additional sealing. This is especially important if street noise has increased, a draft has appeared, and heat is lost in winter. It is best to do insulation in warm weather. Many methods are used for this, including replacing the window. Fortunately, there are building materials that successfully solve this problem. This material is considered to be insulation tape.

About insulation

The microclimate of the room depends on the windows. Due to uninsulated windows, the glass fogs up, cracks and fungus appear on the slopes, and there is always a draft and street noise. To effectively insulate windows, it is necessary to determine the reasons for low thermal insulation.

Most often they are as follows:

Wooden windows

First of all, insulation is required for old window structures for the following reasons:

Previously, glass was secured to the frame with special putty. Over time, it dries out and becomes stained;

the frames dry out, so cracks and gaps appear between the glazing bead and the glass;

the sashes are deformed and are not held tightly to the frame.

Plastic windows

It is mistakenly believed that such windows are quite airtight and therefore do not need insulation. Unfortunately, after a few years the seal collapses, and insulation is indispensable.

There are other reasons why it is necessary to deal with plastic windows:

violation of window installation technology;

distortion of the window structure due to shrinkage of the house;

factory defect of window design;

mechanical damage to structural elements.

Types of insulating tapes

The widespread use of tapes for insulating windows is explained by a number of reasons:

no annual replacement required;

insulation is carried out in a short time on our own;

there is no dirt when pasting, since no water is used;

no traces of adhesive remain on the frame;

there is no diffusion of the adhesive layer with the frame paint.

But this method of insulation also has disadvantages:

after gluing, you cannot open the window sashes;

poor-quality or poorly glued tape lags behind the frame in small areas.

IN construction stores They offer two types of tapes, which differ in the installation method.

Pasting

Foam tape with adhesive base

This type of tape has a wide grip. The adhesive composition is applied during manufacturing (self-adhesive type) or during installation work.

To create self-adhesive tape, polyvinyl chloride, rubber and polyethylene foam (foam rubber) are used.

Due to the plasticity of these materials, the tape is easily compressed to the size of the gap. To ensure that the insulation does not stand out against the background of the window, dyes are added: black, brown, white.

Typically the packaging will indicate the size of the gap that the tape will cover. Popular options with sizes 3 - 7 mm.

The first to be used foam tapes. Their popularity is explained by a number of advantages:

high compression ratio;

the frame does not collapse in places of insulation;

low cost;

high protection efficiency.

Such tapes have negative qualities:

insufficient efficiency for large gaps;

short service life. Effective during one winter season;

in cheap models, the adhesive tape does not stick well;

low resistance to water.

Important!

It is more convenient to use self-adhesive tapes on foam rubber for insulation.

They stay on the window longer and regulate the degree of pressing of the sashes.

Sealing

D - shaped tubular seal with adhesive base

Tapes of this type have a hollow tubular shape, which is why heat is retained. The materials chosen are rubber and polyvinyl chloride.

On one side of the tape there is a groove hook or adhesive coating with paper protection.

It is believed that the groove is more resistant to mechanical stress.

The following qualities are considered advantages:

gaps up to 0.7 cm are blocked;

withstands any temperature changes;

It is possible to choose a color to match the color of the frame;

the use of the window is not limited;

affordable price.

But most of the disadvantages relate to adhesive tapes:

not suitable for all window designs;

when temperature changes, the adhesive layer is destroyed;

with frequent deformations, peeling occurs in glued areas;

The foam tape quickly gets wet and dust sticks to it. For this reason, frequent replacements are carried out.

Tubular seals are checked annually. If necessary, individual fragments are replaced.

As a rule, a tape is selected based on three indicators.

By material

Main advantages:

low cost;

high elasticity, allowing you to close gaps of different sizes.

There are also disadvantages:

Due to the porous structure, moisture is quickly absorbed. The drying process takes a very long time;

low durability. With prolonged use, the material turns yellow and crumbles.

Unfortunately, such tapes are rarely used for window insulation, as they increase the cost of window construction by up to 15%.

Rubber― used for the manufacture of two types of tapes: self-adhesive and sealing.

Tubular seals with groove

Self-adhesive tapes are made on the basis of synthetic rubber and have all of its positive traits: elasticity and resistance to temperature fluctuations.

Rubber seals are not afraid of aggressive environments, so they last a very long time.

Polyurethane foam (PPE)― porous material made of foamed polyethylene.

Due to their high elasticity, the tapes are very effective for small gaps. Good insulating qualities. Due to the presence of air in the structure, a thermal insulating environment is created.

Its use is limited to its ability to high temperature turn into a liquid toxic state.

By manufacturer

In construction stores you can find tapes from different manufacturers.

However, only materials from the following brands are in demand:

Russia - Profitrast, Economy, Zubr.

Germany - KIMTEC, Deventer.

Poland - Sanok.

Domestic manufacturers, as a rule, work using European technologies and produce quality material no worse than foreign models. At the same time, German and Polish ribbons, although more expensive, last longer.

By cost

Insulation tapes are sold retail and in coils from 6 to 10 meters.

Since a standard window requires about 5 meters of self-adhesive insulation, purchases are most often made at retail.

The price range is very wide.

Behind linear meter for Russian material you need to pay up to 15 rubles, and the most expensive German rubber insulation will cost 50 rubles.

Features of preparing windows for insulation

Preparing a window for insulation with tape is almost no different from preparation for other insulation materials. At the same time, there are some peculiarities.

The main stages are as follows:

Everything is removed from the windowsill. The blinds are removed from the window.

The frames are washed with soapy water and then dried. The tape requires a dry and grease-free surface.

The glass is carefully inspected. U wooden windows glass may have cracks. They must be replaced as they are a source of heat loss.

Grooves are prepared for the sealing tape. Shouldn't stay in them old tape, dirt and paint.

Before starting work, they determine the places from which it comes cold air from the street. They are insulated first. Weak points are the sashes, slopes, and window sills.

Insulation with adhesive tape

The insulation technology is not very complicated. First of all, it is necessary to follow the sequence of work.

Plastic windows

Insulation is carried out in the following sequence:

pre-removed old insulation is used, firstly, to purchase similar material, secondly, for preliminary cutting to size of old material.

gluing begins from the top of the window. As you progress, it is removed in small sections protective layer, and the tape is pressed tightly.

More details in our video:

Important!

1. The pasted tape should not have many tears.

2. In the corners the tape is not cut, but wrapped.

Wooden windows

For these windows, in addition to adhesive tape, thin foam rubber is often used. The work is performed in the following sequence:

strips of foam rubber are cut along the window opening;

cut foam rubber is placed between the frames;

The tape is cut to the size of the window;

The tape is applied with a sticky layer to the foam rubber and smoothed with a napkin.

This insulation will last up to three years. But it’s better to do it as shown in the video:

Insulation with sealing tape

Plastic windows

Typically, plastic windows lose heat for two reasons:

breakdown of fittings;
seal wear.

Correct installation of the tape increases the insulating ability of the window. The following sequence of work is recommended:

before installation, the tape is kept at a positive temperature, since this affects its expansion inside the groove;

The tape is cut to fit the window. The joints are cut at right angles. For thermal expansion, a reserve is created: for every meter 1 centimeter of material;

The tape is pressed into the groove with a spatula, and the adhesive strips are removed in small sections.

Important!

1. In the corners of the frame, the tape is connected only end-to-end.

2. To prevent impregnation from leaking out, the tape is not compressed more than the permissible value.

After installing the sealing tape, the locking mechanism is adjusted: the pressure is changed by trunnions, which are located at the end of the sash.

Adjustment is made with a hex wrench. The pressure increases when the trunnion head is installed in a horizontal position.

Wooden windows

The Swedish method of insulating such windows using EuroStrip technology is in great demand. It has the following advantages:

there is no need for annual window insulation;

after ventilation, the tightness of the windows is not compromised;

frame service life increases;

high degree of protection from dust and street noise.

For insulation, two types of tapes are used: rubber and silicone.

By the way, branded Swedish silicone seals are easily inserted into the groove and last up to 20 years.

Installation is performed in the following sequence:

the sashes are removed from their hinges and inspected. Rotten areas are identified and then restored;

So, both types of window insulation tapes deserve attention. Which one is better depends on the condition of the window.

If you choose the right one, the insulation will quickly pay for itself, and the apartment will always be warm and cozy.

To protect the installation seams in window openings from exposure to moisture, use a vapor barrier tape. It is made from butyl rubber or aluminum. This material glued to damp mounting foam at the seams, extending the life of the windows.

When installing a window in an opening, remember that its service life is related to how competent the installation is. Even the most quality designs will not be used long time if the installation was performed incorrectly. Due to improper work, moisture will gradually penetrate the walls, leading to the destruction of building materials and the spread of mold.

Vapor barrier tape

When installing the frame, consider several important points:

WITH inside we make the premises more dense layer mounting solution (for example, foam).
To ensure high-quality sealing of all gaps, we use three-layer protection - the outer material protects from the effects of precipitation, the middle layer is responsible for thermal insulation, and the coating inner surface- for vapor barrier.

Vapor barrier provides reliable protection a thermal insulation layer against condensation, which is present not only in the bathroom, but also in an ordinary room. In the process of finishing window slopes stick a special tape. The principle of vapor barrier is based on blocking the contact of moisture with polyurethane foam, which forms the middle protective layer. Materials with low elasticity and permeability to water and air are suitable for these purposes. When installing windows, you cannot save on vapor barriers. Such neglect will lead to rapid wear of frames, plaster and finishing materials.

To protect the seam, special vapor barrier tapes are usually used. They come in a coiled and compressed sponge-like material. Absorbing moisture, the material swells, sealing all existing cracks. Vapor barrier tape for plastic windows has a number of advantages:

1. isolates moisture;
2. It is consumed economically, with virtually no waste;
3. does not emit toxic substances;
4. Easy to stick;
5. has long term operation.

2 Classification - what characteristics to pay attention to

Moisture insulation tapes are available with one or two strips of adhesive. The second option allows you to process the window-wall joint more efficiently. The material is classified according to periods of use:

summer (air temperature – 5-40 °C);
winter (temperature below 5 °C).

Depending on the nature of the surface being treated, the tapes are produced in various sizes, making it possible to isolate any seams. When choosing a material, keep in mind that it must exceed the width of the gap by 4.5 cm. For work on the outside of the building, tapes made of foam materials are suitable, which will ensure reliable sealing.

Moisture Insulation Tape

Adhesive finishing material, made of butyl rubber, is intended for processing window, balcony, door frames and connections between panels. There is a non-woven layer inside it. After gluing, such a strip is primed, plastered, wallpapered or painted. There is a full-butyl vapor barrier tape made using the Robiband system. It provides more high-quality processing assembly seam.

Metallized vapor barrier material used for gluing seams with joints in rooms with high air humidity - bathrooms, baths, saunas. A layer of glue over the entire surface in this form greatly simplifies the work process. Manufacturers produce metallized tape different widths. When selecting material, add 45 mm to the seam width.

The tape, which has a protective strip of polypropylene, withstands mechanical stress well. In addition, it does not react with acids, organic solvents and alkalis.

3 We understand the variety of types of tapes - VS or GPL?

First on the list is PSUL (pre-compressed self-expanding sealing tape). It ensures a high-quality fit of the window frame or door frame to Wall. This tape is used for vapor barrier of external joints and seams.

The next material is vapor barrier BC. It is used to seal seams when dry finishing is performed. For example, under sandwich panels, drywall, plastic surfaces, etc. The tape has a layer of adhesive across its entire width - this property greatly simplifies the installation process. There is an improved version - BC+. It is supplemented with anti-adhesive film. This additional coating ensures strong adhesion of the insulation to building materials.

Robiband tape VM for vapor barrier

Robiband tape VM for vapor barrier is the next high-quality material option for processing seams. It is used for interior work, and wet is applied on top plaster mortar. Vapor barrier VM+ is a more complicated option with better performance characteristics.

The last type is GPL (hydro-vapor barrier material). It is made from foamed polyethylene High Quality. The tape has one laminated side, as well as an additional metallized layer. Its second surface is completely covered with glue. This tape is universal, that is, it can be used for all types of work. Its variety is GPL-S tape, which has similar characteristics.

4 How to glue insulation - we work without errors

Vapor barrier material not only provides protection from moisture, but also has an alternative property when applied correctly - sound absorption. Vapor barrier tape is applied to the seams in one piece; there should be no breaks. Before starting work, measure the length of the surfaces to be treated.

The pasting process consists of several steps:

1. Clean the window opening from dirt, dust and debris.
2. Before installation, remove the PVC window and wipe with a dry cloth.
3. Place the structure in place and mark the places where the tape is attached on the frame and wall.
4. The tape is attached to window frame before applying foam along the seam.
5. Take out the structure and stick a vapor barrier on its surface around the perimeter.
6. Before replacing the window, remove the remaining protective film from the adhesive surface.
7. When gluing the material, do not allow wrinkles to form. This defect will allow drops of liquid to pass under the vapor barrier, impairing performance.

To window design has served for a long time, its installation must be carried out with strict adherence existing technology. Outer material for steam, heat and water insulation it is necessary to glue after polyurethane foam completely polymerizes. We process the seam under the window sill last.

If the tape is glued under a layer of plaster, then it must have a special layer that will ensure strong adhesion to building material. Uneven joint between wall and window frame cover it with a flashing, and a vapor barrier is glued onto it. The use of building materials for wall decoration is permissible only if the requirements for water permeability are fully met.

If metallized tape is used for vapor barrier, then additional reinforcement may be required when applied to a rough surface. To enhance the adhesive effect, use self-adhesive tape with one or two strips of glue. It is additionally used to process vapor barrier joints, eliminating and smoothing out defects (places of peeling and wrinkling) formed during the work process.

Question about the need for vapor barrier of windows by gluing the joints of window frames and slope outer wall vapor barrier tape has no clear answer. But having decided to install plastic windows in your house, it is very useful to understand some aspects of the problem:

The use of vapor barrier tapes increases the cost of installation. But it is not a fact that high-quality installation will be achieved by applying tape. Preparation of the base for the tape is very important, and the sticker technology has subtleties. Installation violations lead to the fact that the tape simply peels off and ceases to perform its task of vapor barrier. In addition, the unevenness of the opening makes it difficult to install the tape, and high-quality preparation is not always done.

One of the opinions of experts is that with optimal organization of heating and air exchange in the house, windows do not produce condensation or mold in the corners. The dew point is at outside thermal insulation wall layer, and there cannot be any mold in the window corners. It does not matter whether the windows are sealed with PSUL and a membrane or not. But if there are problems with ventilation hood and the heating in the house is not working well, then vapor barrier of the windows will give positive effect(although heating and ventilation problems need to be solved comprehensively). In any case, if a company providing services for installing PVC windows stipulates the conditions for their future use by the customer and offers options for sealing joints, this is definitely a plus for the company. Because there are “companies” and employees who “don’t like” the abbreviations PSUL and argue that they don’t spare foam, and the window is guaranteed for a whole year. Unfortunately, the installation is not always successful and in the second winter there is no blowing from the cracks of the windows, and in the off-season there is no condensation along the slopes.

The seams between window frames and external walls are one of the weakest links and require careful water and thermal insulation. Polyurethane foam, filling the space between the opening and the frame, perfectly insulates from air noise and performs the task of thermal insulation of the joint. But moisture and ultraviolet radiation can destroy foam in a period of several months to two years. They solve this problem by protecting the foamed joint with sealing. Waterproofing is carried out on the outside so that atmospheric moisture does not fall on the porous insulation; from the inside of the room, the joint is taped with vapor barrier tape.

A vapor barrier is necessary to prevent moisture from the outside air from penetrating into the thermal insulation materials junction. According to standards internal seams for PVC windows must have a vapor permeability of no more than 0.01 mg/m*h*Pa. The vapor barrier is installed before installing the windows, sealing the joint from the inside: the window block is installed in the opening without fixing, areas for sticking tapes are marked, then the block is removed and vapor barrier tapes are glued.

Means for protecting the joints of windows and balcony doors:

Silicone sealants
Insulation with padding - cords, tow, moss
Foil tapes
PSUL tapes and butyl rubber tapes

For the right choice It is important to consider the type of window finish and the position of the joint. To protect the joints of frames and plasterboard and plastic slopes(dry cladding) and to protect windows with plastered slopes, various insulation means are used. For wooden windows installed in log houses, natural fillers are usually used - sphagnum, jute, flax tow, etc.

Vapor barrier device

There are three layers:

From the inside - thermal protection prevents heat loss from the room to the street
The middle load-bearing insulating layer provides thermal insulation and sound insulation. These problems are solved by polyurethane foam or other porous material. It is rational to include vapor barrier self-adhesive tapes in this inner layer, if the window unit is mounted in wet areas– kitchens, baths or showers
The outer layer waterproofs the joint and protects against the penetration of cold street air

Vapor barrier tapes are available with a one-sided adhesive layer and double-sided. A one-sided sticker is used if the film is mounted on the side surface of the window frame. Double-sided tape gives an advantage in choosing fasteners: on the frame or in window opening. According to climatic modifications, the tapes are also produced in two types - for areas with low winter temperatures – winter option tape, and for areas where temperatures do not fall below +5⁰С - a summer option.

The base for the adhesive layers of the tapes is butyl rubber or metal.

Main types of vapor barrier tapes:

PSUL, or pre-compressed sealing tape - is used for finishing and vapor barrier of external joints, ensures a tight connection of the window frame with outer wall. The base material is butyl rubber; the thickness and elasticity of the tapes provide good insulation.
BC - vapor barrier tapes for sealing joints for dry finishing of slopes - made of plastic or plasterboard. sizing with BC tapes reduces the risk of condensation.
VM - vapor barrier tapes attached to the window frame, with an overlap, in order to improve the thermal insulation of joints.
GPL is a polyethylene foam tape, laminated on one side, with metal strips and an adhesive layer over the entire width.

In addition to the main layer of non-crosslinked polyethylene foam, which has a thickness of 2 mm and is waterproofing, the GPL tape has a second layer - both vapor barrier and protective. The thickness of the outer layer is only 20 microns, the material is polypropylene.

GPL tapes are used for all types of door and window blocks as universal ones. They combine two tasks - waterproofing and vapor barrier. The structure of foamed polyethylene is elastic and closed-porous, so the material does not absorb moisture and its hygroscopicity is almost zero. The tapes are flexible and suitable for installation on uneven surfaces. Metal lamination and the quality of the main polymer (polypropylene as a protective layer) determine chemical resistance in both acidic and alkaline environments, and as a result, good durability of GPL tapes.

They produce GPL tapes in standard sizes width of window and door units, width 9; 12; 15; and 20 cm, in rolls of 15 m.

Features of installation of vapor barrier tapes

The minimum temperature for installing tapes is +10⁰С
The tapes are applied to the prepared surface - complete cleaning of all contaminants, dust removal and degreasing. Preparation is extremely important for proper operation vapor barriers
Marking lines for attaching vapor barrier tapes. Determine the position of the frame in the opening without fixing, mark the lines for sticking the tapes, then remove the frame and install the tape according to the markings
Protective paper strips are removed from the tapes immediately before the final installation of the frames
After gluing the tapes, the joint is filled with foam
The tapes under the window sills are installed last
If it is planned to use a vapor barrier tape wet plaster, then the outer side of the tape should ensure adhesion with the solution. From the range of vapor barrier tapes it is possible to choose a material with the desired properties
Glue the tapes along the perimeter of the frames without breaks, in continuous stripes. Overlapping and overlapping of tapes is not necessary; at joints they are used adhesive compositions, recommended by manufacturers, or tape

The issue of the need for vapor barrier of windows is decided by each owner, based on the specific operating conditions of the windows. Budget options Installation of tape is absolutely excluded. But many experts believe that vapor barrier of windows is not reinsurance, but a real opportunity to increase the service life window systems and improve the indoor microclimate, and saving in this case is not an entirely correct approach.

Salute, readers!

I love thematic forums, where everyone has their own opinion and teaches others.

What battles sometimes flare up there!

This time, at one of these forums, I was able to witness a debate about the need to use vapor barrier tape.

One forum member, foaming at the mouth, argued that it was not needed and this was a good advertising ploy for one of the Western companies, another explained why it would be bad without it.

If you don’t yet know what a vapor barrier tape is, then this topic is just for you.

Vapor barrier tape for windows

Vapor barrier tapes for windows, like good finish slopes and installation seams will ensure decent window performance. In order for the window in your home to function well and for a long time, you should not miss such a moment as installing a vapor barrier tape.

The use of sealed tapes to isolate the assembly seam from vapors and moisture in the adjacent room prevents condensation from escaping onto the slopes.

If you have a kitchen, a room with a swimming pool or a bathhouse, then installing vapor barrier tape on your windows is a must.

Types of vapor barrier tape

Tapes can be either with one or two adhesive strips. Two adhesive strips are intended for attaching the tape with one side to the window and the other to the wall.

Vapor barrier tapes are also classified according to weather periods:

For summer period with air temperature from + 5°C to + 35°C;
For winter period with temperatures below 0°C.

The width of the tape also varies depending on needs, which allows you to ensure reliable vapor barrier seams of various sizes. When choosing vapor barrier tapes, keep in mind that its width should be about 45 mm greater than the width of the installation seam.

Tapes for outdoor work consist of foamed materials (this work requires well-sealing materials with plaster mortar, which will provide the required vapor barrier of the outer layer).

Vapor barrier tape can be butyl rubber, for sealing interpanel joints or for installing door or window blocks.

This tape contains non-woven fabric. During installation, it is primed, plastered and painted. This type is also self-adhesive.

To protect against high humidity of the installation seam for dry finishing of slopes, there are metallized vapor barrier tapes on the market.

General information on installing vapor barrier tape

Initially, you need to prepare your opening: clean the internal and outer surface opening and frame. The frame is inserted into the opening and is temporarily not secured.
Then gently mark a line on the frame for attaching the vapor barrier tape.
After carrying out the calculations and marking the window, we remove the frame and glue our internal vapor barrier tapes. We do not remove the paper strip that protects the inner adhesive layer, which will subsequently attach to the walls.

As a rule, the installation of a vapor barrier tape on a structure is carried out before the seam foams.

Helpful advice!

Therefore, before finishing, dampening and filling with foam, you can remove the protective paper strips from the vapor barrier tapes.

This will allow you not to lose the adhesive properties of the tape. If you are driving hidden installation, then the tape should be attached to the ends of the structure from above and on the sides, and to the installation profile from below.

External thermal insulation tapes can be glued no earlier than the polyurethane foam has been completely polymerized.
Installing a vapor barrier tape under the window sill can be done last. When installing a vapor barrier tape under a plaster layer, the tape must have an outer coating, which will ensure the necessary adhesion to this plaster layer.

If there is a window quarter with gaps between the frame and the wall, another technique is used: the uneven joint can be covered with a window strip, and a vapor barrier tape can be applied to it.

Installation of vapor barrier tape on windows is installed in a continuous layer along the entire contour of the opening.

Do not forget that the use of finishing building materials in combination with a vapor barrier tape is allowed only if the moisture-permeable characteristics are observed.

Self-adhesive hydro-steam and heat-insulating foil tape (vapor barrier)

Self-adhesive GPL tape is a reliable solution to problems associated with heat, hydro, and vapor barrier of assembly seams, joints, joints and junctions in various building structures– window and door blocks, products made of metal, concrete, wood, plastic, etc.

The vapor barrier layer of the material creates reliable waterproofing, thereby preventing the occurrence of spores, fungi and mold, which significantly extends the life of the structure.

Heat losses are significantly reduced and energy costs are significantly reduced.

The adhesive layer simplifies the fastening of the tape, making installation simple and easy, while ensuring reliable fastening tapes on all types of building materials.

GPL - Self-adhesive foil tape for hydro-steam and thermal insulation (vapor barrier).

The surfaces to be treated must be clean, dry and grease-free. The tape is unwound from the roller (width 90,120,150,200 mm) and cut into pieces of the required sizes.

Remove the protective film and, without stretching it lengthwise, stick the tape onto the surface to be treated. Press the tape tightly with your hands or smooth it with a roller, avoiding the formation of air bubbles.

Supplied in boxes 420x420x600 mm.
Recommended installation temperature is not lower than +10°C.

Self-adhesive heat-, hydro-, vapor barrier tapes GPL - consist of foamed polyethylene laminated on one side with a metallized polypropylene film, on the other side a layer of special waterproof adhesive is applied, which allows the material to be securely fastened to metal, brick, concrete, wood, plastic and other structures .

Installation of internal vapor barrier sealing tape

For internal sealing of the assembly seam, the following is used:

a) vapor barrier tape (duplicated) based on aluminum foil, laminated with non-woven fabric, allows you to protect the installation seam from the inside from moisture and prevents it from escaping from the seam to the surface internal slopes.

For easy and reliable fixation, the tape contains two adhesive strips of glue and butyl, located on two different sides. It is recommended to use it around the entire perimeter of the window for subsequent finishing of slopes using a dry method.

b) the vapor-tight sealing tape is made of non-woven fabric coated with a self-adhesive plastic-elastic mass based on butyl rubber with a high degree of adhesiveness.

The peculiarity of butyl rubber tapes is their fairly heavy weight. And, if you compare butyl rubber and reinforced foil tapes with the same width of 120 mm, it turns out that reinforced foil tape is almost 5 times lighter than butyl rubber tape.

The low weight of the tapes makes it easier to work with them during installation, and also significantly reduces transportation costs when transporting tapes over long distances.

However, tapes based on reinforced foil with adhesive strips have adhesion only to a well-cleaned and degreased surface of the internal slope, while butyl rubber tapes have a tighter fit and better adhesion to the wall opening.

To install the internal vapor barrier sealing tape, you must do the following:

Cut the tape into pieces equal to the width and length of the window +10 cm (to form corner connections). Joining of tapes along the length is allowed “overlapping”, at least ½ of the width of the tape.
Remove the protective paper from the vapor barrier tape from the side of the duplicated strip and glue it to the frame profile from the outside.
The tape is attached by means of a self-adhesive duplicated mounting strip in a tensioned state (tightly, without folds or bulges) to the outer surface of the box from the inside vertically and horizontally across the ceiling. The inner edge of the adhesive layer must coincide with the inner edge of the frame. The tape protecting the butyl rubber layer is not removed at this stage of installation.

The adhesive strip has a fairly high resistance to low temperatures without loss of adhesive properties.

Lack of adhesion can occur if the acrylic adhesive strip is left in the cold for a long time with the release paper removed.

Also, the adhesion of the adhesive strip is reduced when working with cold window blocks, since when a worker breathes, steam (moisture) is released, which partially condenses on the surface of the cold window block, which also reduces the adhesion of the adhesive strips.

To prevent this defect, it is recommended to keep the adhesive layers with the anti-adhesive paper removed for the minimum possible time, and also to wipe the surface of the window block with a dry rag or paper napkin immediately before gluing the tapes to it.

How to properly apply vapor barrier tape on PVC windows

Question: How to properly use vapor barrier tape for PVC windows and at what temperature?

Answer: Installation of vapor barrier tapes on plastic windows is carried out as usual in those rooms where there is high humidity air-kitchen, sauna, swimming pool.

The tape allows you to protect the installation seam from moisture and steam emanating from the room and thus prevents condensation from escaping onto the window slopes. Vapor barrier tapes are produced with one or two adhesive strips.

The tape with two adhesive strips is very convenient to attach to the window and to the slope. Vapor barrier tapes are divided into summer and winter, depending on the weather conditions in the room.

Summer tapes can be used at air temperatures from +5 to +35C, and winter tapes at air temperatures below 0 degrees. You need to choose a tape for windows of such a width that it is 45 millimeters wider than the width of the mounting seam. This will allow you to ensure reliable vapor barrier at the installation seams of your windows.

The technology for installing windows and using vapor barrier tape is as follows. We clean the opening from dirt and dust, install the window frame and, without securing it, mark the lines for attaching the vapor barrier tape on the walls of the opening and on the window frame.

We remove the frame from the opening and glue a vapor barrier tape onto it, protective strip on the part that will be glued to the wall, we do not remove it!

Helpful advice!

We install vapor barrier tape on a PVC window with one piece of tape, without breaks!

Now you can assemble the window with sashes and install them completely in their place. We install the vapor barrier tape on the window sill last.

Materials for window installation

PSUL tape.

It is used when installing window blocks to create a ventilated assembly seam.

Corresponds to GOST 30971-2002 “Installation seams of joints connecting window blocks to wall openings.”

Helpful information

Installation of PVC windows involves the use of special insulating materials. This category includes mounting foam for PVC windows and tape. Each of these materials has a specific purpose. As a rule, the tape serves to isolate seams from dust and moisture, preventing the formation of fungus and mold in the joints. In turn, the foam compensates for the effects of temperature changes and provides reliable sound insulation.

Mounting tapes for windows

The tape is selected taking into account its functional purpose. We offer mounting tape for plastic windows to buy for any task - for sealing ebbs or slopes, window sills or window openings. We recommend paying attention to the PSUL feed.

At a relatively low cost, it has excellent performance parameters, reliably protecting seams from dust and moisture. In addition, its installation is carried out without special tools. The self-adhesive surface adheres tightly to the base without much effort.

Mounting foam for windows

Insulating windows with polyurethane foam has recently become especially important. By correctly installing the window unit, you can significantly reduce heat loss. Naturally, the effectiveness of such insulation is determined by the properties of the material. And here the question usually arises: polyurethane foam for PVC windows - which is better? Basically, the insulating characteristics depend on the components included in the foam, as well as on the production technologies used by the manufacturer.

Buy PSUL in Moscow

Our category is represented by the German company Bauset, which has been one of the leading manufacturers in Europe for many years. If you follow the manufacturer's instructions, the consumption of polyurethane foam on the window is minimal - at low costs you can reliably seal the window unit and extend its service life. In the adjacent sections of the catalog you can find everything necessary tools to carry out work.

Vapor barrier is required for plastic windows. Vapor barrier tape allows you to close joints, seams, and protect the structure from wind and precipitation. Thanks to this element, cold air will not enter the room through the joints, which will ensure the greatest airtightness of the room and minimal heat loss.

How to install windows correctly?

Modern builders most often use polyurethane foam for installation. M O Installation tape for windows together with sealant is applied after the foam has dried. It is needed in order to protect the material from moisture, as well as close possible cracks and stop the access of cold air to the room. If this condition is neglected, in less than a year cracks will appear between the window frame and the wall, through which cold air will enter the room. Drafts will appear, the windows will sweat a lot and freeze at the joints.

What is vapor barrier used for in plastic structures?

It is worth considering that the more correctly the installation is done, the more reliable the structure will be and will last longer. Even if , but are inserted incorrectly, you will not get the desired effect.

It is necessary to ensure that workers are mandatory met the following conditions:

The inside of the installation gap should be filled with foam that is thicker than the outside.
The system must be three-layer. The first layer on the street side protects the entire cake from weather conditions, the middle layer is responsible for thermal insulation, and the inner layer protects against condensation.

Vapor barrier tape is necessary to protect the structure from water vapor.

To ensure that the vapor barrier does not interfere with plastering, special tapes should be used, over which the room can be finished.

What should you know about sealing?

Most often, windows are fastened using special bolts and: this material simultaneously serves as a reliable fastener, allowing you to adjust the position of the frame before the foam hardens, and as a high-quality insulation. However, sealing for the material is extremely important, since when moisture gets in, the foam begins to deteriorate over time, crumble and turn yellow, which negatively affects its properties.

Excellent for foam protection mounting tape for windows. Even if you are going to use platbands, which will protect the structure from weather conditions, and can also give the frame decorative look, before installing them it is worth gluing the tape. It will help make the insulation high-quality, while making the work not much more expensive.

The most inexpensive and easiest to install vapor barrier for windows is a special tape, the sticker of which can be applied by anyone.

To protect installation seams in window openings from moisture, use vapor barrier tape. It is made from butyl rubber or aluminum. This material is glued to damp polyurethane foam at the seams, extending the life of the windows.

Is it worth spending money on protecting window seams?

When installing a window in an opening, remember that its service life is related to how competent the installation is. Even the highest quality structures will not be used for a long time if the installation is carried out incorrectly. Due to improper work, moisture will gradually penetrate the walls, leading to the destruction of building materials and the spread of mold.

When installing the frame, consider several important points:

On the inside of the room we make a denser layer of the mounting solution (for example, foam).
To ensure high-quality sealing of all gaps, we use three-layer protection - the outer material protects from the effects of precipitation, the middle layer is responsible for thermal insulation, and the coating of the inner surface is for vapor barrier.

Vapor barrier provides reliable protection of the thermal insulation layer from condensation, which is present not only in the bathroom, but also in an ordinary room. In the process of finishing the window slopes, we glue a special tape. The principle of vapor barrier is based on blocking the contact of moisture with polyurethane foam, which forms the middle protective layer. Materials with low elasticity and air and water permeability are suitable for these purposes. . When installing windows, you cannot save on vapor barriers. Such neglect will lead to rapid wear of frames, plaster and finishing materials.

1. isolates moisture;
2. It is consumed economically, with virtually no waste;
3. does not emit toxic substances;
4. Easy to stick;
5. has a long service life.

Classification - what characteristics to pay attention to

summer (air temperature – 5-40 °C);
winter (temperature below 5 °C).

Moisture Insulation Tape

An adhesive finishing material made from butyl rubber is intended for processing window, balcony, door frames and joints between panels. There is a non-woven layer inside it. After gluing, such a strip is primed, plastered, wallpapered or painted. There is a full-butyl vapor barrier tape made using the Robiband system. It provides better processing of the assembly seam.

Metallized vapor barrier material is used for gluing seams with joints in rooms with high air humidity - bathrooms, baths, saunas. A layer of glue over the entire surface in this form greatly simplifies the work process. Manufacturers produce metallized tape of different widths. When selecting material, add 45 mm to the seam width.

The tape, which has a protective strip of polypropylene, withstands mechanical stress well. In addition, it does not react with acids, organic solvents and alkalis.

We understand the variety of types of tapes - VS or GPL?

First on the list is PSUL (pre-compressed self-expanding sealing tape). It ensures a high-quality fit of the window frame or door frame to the wall. This tape is used for vapor barrier of external joints and seams.

Robiband tape VM for vapor barrier is the next high-quality material option for processing seams. It is used for interior work, and a wet plaster solution is applied on top. Vapor barrier VM+ is a more complicated option with better performance characteristics.

The last type is GPL (water vapor barrier material). It is made from high quality foamed polyethylene. The tape has one laminated side, as well as an additional metallized layer. Its second surface is completely covered with glue. This tape is universal, that is, it can be used for all types of work. Its variety is GPL-S tape, which has similar characteristics.

How to glue insulation - we work without errors

The pasting process consists of several steps:

1. Clean the window opening from dirt, dust and debris.
2. Before installation, remove the PVC window and wipe with a dry cloth.
3. Place the structure in place and mark the places where the tape is attached on the frame and wall.
4. The tape is attached to the window frame before applying foam along the seam.
5. Take out the structure and stick a vapor barrier on its surface around the perimeter.
6. Before installing the window in place, remove the remaining protective film from the adhesive surface.
7. When gluing the material, do not allow wrinkles to form. This defect will allow drops of liquid to pass under the vapor barrier, impairing performance.

In order for a window structure to last long enough, its installation must be carried out in strict compliance with existing technology. External material for steam, heat and water insulation must be glued after the polyurethane foam has completely polymerized. We process the seam under the window sill last.

If the tape is glued under a layer of plaster, then it must have a special layer that will ensure strong adhesion to the building material. The uneven joint between the wall and the window frame is covered with a stripping, and a vapor barrier is glued onto it. The use of building materials for wall decoration is permissible only if the requirements for water permeability are fully met.
