Windproof tape for plastic windows. What is a vapor barrier tape for a window and why is it used during installation

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 the joints 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 functional purpose. We offer mounting tape for plastic windows buy for any task - for sealing ebbs or slopes, window sills or window openings. We recommend paying attention to the PSUL tape.

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

Mounting foam for windows

Insulation of windows with polyurethane foam has recently become especially important. Having correctly installed 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 that make up 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 mounting foam on the window is minimal - at low cost, you can reliably seal the window unit and extend its service life. In the neighboring sections of the catalog you can pick up everything necessary tools to do the work.

Joints, seams of any structures are the most vulnerable places. The same can be said about the windows installed in the window opening. It is the mounting seam that will be the weakest point in the entire structure. Through a poorly laid seam, heat can escape, moisture and extraneous sounds from the street can penetrate, and finally, the condensate that forms during the temperature difference will accumulate inside the insulation and worsen its characteristics, leading to destruction. The description of the characteristics of the mounting seam and the technology of its installation is given special attention in GOST. On the this moment GOST 30971-2012 is valid.

Technology features. Why you need vapor barrier tape

According to GOST, the assembly seam must be three-layer. Each layer has its own function:

The middle layer - the main one - provides heat and sound insulation due to the porous structure.
The outer layer protects against moisture coming from the street (it removes it) and from UV rays.
The inner layer is a vapor barrier. In fact, it traps heat in the house and prevents the steam that accumulates in the interior of the room from penetrating inside the insulation layer.

Thus, compliance with the technology of the seam device is necessary in order to prevent the penetration of moisture, the formation of condensate, and to improve the heat and sound insulation properties. Refusal to install insulating layers will reduce the cost of installation and construction by about 15-20%, in general, but GOST does not allow such cases.

Classification of vapor barrier for windows

To install a PVC window, a vapor barrier tape is used in all its variety of varieties and a diffusion vapor-permeable tape.

Tapes can have one or two adhesive surfaces. The former are installed on the frame itself, the latter can be installed in window opening, gluing them to the wall and to window profile. The range is divided into winter and summer options. Summer ones are designed for installation at temperatures from +5 degrees to +35 degrees, winter ones - for installation at temperatures of +5 degrees and below. Moreover, when installed in winter time heating of the surface of the window opening is necessary.

The tape should be approximately 5 cm wider than the installation seam.

According to the material of manufacture, two types of tapes are distinguished:

Butyl rubber tape with non-woven reinforcement for joint sealing.
The tape is metallized, intended for installation in damp rooms.

Tape types

The functionality of the tapes is different, therefore, when installing windows, different varieties are used depending on the goals at each specific stage. The tapes should be reviewed.

	Production material	Where applicable	Properties	Peculiarities
PSUL	Polyurethane	It is used when organizing a ventilated assembly seam from the outside. Allows for high quality seams. Acts as sound insulation when glued to the lower surface of the tide.	Provides a tight fit of the frame to the wall.	It is necessary to unwind the tape (it is supplied rolled into rollers) immediately before installation. Over time, it expands and loses its sealing properties. The width of the PSUL tape must exceed the width of the mounting gap.
	Non-woven material. BC+ - foil.	Used when installing internal slopes. Combined with plastic, drywall, prevents condensation.	Prevents moistening of the insulation used for insulation of slopes, in particular mineral wool. BC+ has an adhesive double-sided layer. It is an effective vapor and thermal insulation	There is an adhesive layer across the entire width. BC+ is thicker than BC.
	Non-woven material. VM + - foil.	It is used when finishing internal slopes, but under plaster.	Does not allow the penetration of condensate to the mineral wool insulation. VM+ has an adhesive layer on both sides.	Provides adhesion to plaster. VM+ is more resistant to moisture.
	It is made of foamed polyethylene, which is laminated on one side with a metallized film. On the other side, an adhesive layer is applied.		Combines the properties of several tapes. It has increased elasticity, mechanical strength and resistance to aggressive chemicals.	It may not adhere well to gas and foam concrete.
	A thicker layer of polyethylene foam is used than HPL. Metallized layer based on polyurethane film.	Universal tape. Used for heat, hydro and vapor barrier.	The difference from the GPL tape is that an additional adhesive strip has been removed from the side of the metallized film. Tape has the best thermal insulation characteristics. Reflects heat effectively.	Sufficiently voluminous, which is inconvenient when finishing slopes.
Diffusion Tape	Polyester fabric with self-adhesive strips based on butyl rubber.	It is used to seal the assembly seam from the side of the tide.	Vapor permeable from the inside, has waterproofing properties from the outside.	Resistant to UV rays.
Butyl rubber mounting tape	Butyl rubber	It is installed between the window sill and the insulation.	Protects from blowing.	There is a self-adhesive layer.

The procedure for installing a vapor barrier tape

The vapor barrier tape is installed after performing the preparatory procedures: dismantling the old window, cleaning the opening from debris, dust, sealing and leveling large irregularities.

The window opening is wiped with a dry cloth and the window structure is pre-installed. In the process, the future location of the PSUL vapor barrier tape is marked.
The window is removed from the window opening and a vapor barrier tape is glued to the frame with a 5 mm indent from the markings. In the corners, the tape is glued end-to-end, for which the tape is initially cut off with an allowance that will go to fit. The surface must be degreased and dust-free.
Tape for slopes is glued to the side profiles and the top one. leave an overlap of about 10 cm.
Install the window. Foam the seam.
The mounting seam is closed from the outside with diffusion tape.
Before installing the tide, PSUL is glued along its lower surface.
On the seam at the bottom of the box with inside fix the metallized vapor barrier tape.
The tape on the window sill is glued last.

To protect the mounting seams in window openings from moisture, a vapor barrier tape is used. It is made from butyl rubber or aluminum. This material is glued to wet 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 will be. Even the highest quality structures will not be used for a long time if the installation is not done correctly. 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 a few important points:

On the inside of the room, we make a denser layer of mounting solution (for example, foam).
For high-quality sealing of all gaps, we use three-layer protection - the outer material saves 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 a heat-insulating layer from condensate, which is present not only in the bathroom, but also in a normal room. In the process of finishing window slopes, we glue a special tape. The principle of vapor barrier is based on blocking the contact of moisture with the mounting foam, which forms the middle protective layer. For these purposes, materials with low elasticity and throughput for water and air. When installing windows on a vapor barrier, you can not save. 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 the form of a coiled and compressed sponge-like material. Absorbing moisture, the material swells, sealing all existing gaps. The vapor barrier tape for plastic windows has a number of advantages:

1. insulates moisture;
2. it is spent economically, practically without waste;
3. does not emit toxic substances;
4. easy to stick;
5. has a long service life.

2 Classification - what characteristics to look for

Tapes for moisture insulation are produced with one and two strips of glue. The second option allows you to process the joint of the window with the wall more efficiently. The material is classified by periods of use:

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

Depending on the nature of the surface to be treated, the tapes are produced in various sizes, so that any seams can be isolated. When choosing a material, keep in mind that it should exceed the gap by 4.5 cm in width. Foam tapes are suitable for work from the outside of the building, which will provide reliable sealing.

Moisture Insulation Tape

Adhesive finishing material, made of butyl rubber, is designed for processing window, balcony, door frames and joints between panels. It has a non-woven layer inside. After gluing, such a strip is primed, plastered, wallpapered or painted. There is full butyl vapor barrier tape made according to 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 humidity air - 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 width of the seam.

The tape having a protective strip from polypropylene well maintains mechanical influence. In addition, it does not react with acids, organic solvents and alkali.

3 Understanding the variety of types of tapes - VS or GPL?

First on the list is PSUL (pre-compressed self-expanding sealing tape). It provides 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.

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

Robiband VM tape for vapor barrier

Robiband VM tape for vapor barrier - next quality option seam material. It is used for internal works, and a wet plaster solution is applied on top. Vapor barrier VM + is a sophisticated option with better performance.

The last type is GPL (hydro vapor barrier material). It is produced from high quality polyethylene foam. 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 stick insulation - we work without errors

The vapor barrier material not only provides protection against moisture, but also has alternative property with proper gluing - sound absorption. Applying a vapor barrier tape to the seams is done in one piece, there should not be any gaps. Before starting work, measure the length of the surfaces to be treated.

The gluing process consists of several steps:

1. Clean the window opening from dirt, dust and debris.
2. Before installation, remove the PVC window and wipe it with a dry cloth.
3. Put the structure in place and mark on the frame and wall where the tape will be attached.
4. The tape is attached to window frame before applying foam at the seam.
5. Remove the structure and stick a vapor barrier on its surface around the perimeter.
6. Before reinstalling the window, remove the remaining protective film from the adhesive surface.
7. When pasting the material, do not allow the formation of wrinkles. This defect will allow drops of liquid to pass under the vapor barrier, degrading performance.

In order for the window structure to serve for a long time, its installation must be carried out with strict observance of the existing technology. Outer material for steam, heat and water insulation, it is necessary to glue after the mounting foam is 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. Irregular joint between wall and window frame closed with a flashing, and a vapor barrier is glued on it. The use of building materials for wall decoration is permissible only if the requirements for water permeability are fully met.

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

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

The use of vapor barrier tapes increases the cost of installation. But not the fact that the tape sticker will be achieved high quality installation. The preparation of the base for the tape is very important, and the sticker technology has subtleties. Violations of installation lead to the fact that the tape simply peels off and ceases to fulfill its task of vapor barrier. In addition, the unevenness of the opening makes it difficult to install the tape, and they do not always know how and do high-quality preparation.

One of the opinions of experts is that with the optimal organization of heating and air exchange in the house, the windows do not give any condensate or mold in the corners. The dew point is from outer side a heat-insulating wall layer, and there can be no mold in the window corners. It does not matter whether the PSUL windows are glued with a membrane or not. But if there are problems with ventilation hood and the heating does not work well in the house, then the vapor barrier of the windows will have a positive effect (although the problems of heating and ventilation must be addressed comprehensively). In any case, if a company providing services for the installation of PVC windows discusses the conditions for their future operation by the customer and offers options for sealing joints, this is definitely a plus for the company. Since there are “companies” and employees who “do not like” the abbreviations PSUL and argue that they do not spare foam, and the guarantee for the window is a whole year. Unfortunately, as a result, the installation is not always successful and for the second winter it does not blow from the cracks of the windows, and in the off-season there is no condensate along the slopes.

The seams between window frames and exterior walls are one of the weakest links and require careful hydro and thermal insulation. Mounting foam, filling the space between the opening and the frame, perfectly insulates from airborne noise and performs the task of thermal insulation of the joint. But moisture and ultraviolet light can destroy the foam in a period of several months to two years. Solve this problem by protecting the foamed joint with sealing. From the outside, waterproofing is performed so that atmospheric moisture does not get on the porous heaters, from the inside of the room the joint is glued with a vapor barrier tape.

A vapor barrier is needed to prevent moisture from the outside air from penetrating into the thermal insulation materials joint. According to the norms, internal seams for PVC windows should have a vapor permeability of not more than 0.01 mg / m * h * Pa. The vapor barrier is mounted before the windows are installed, sealing the joint from the inside: the window block is installed in the opening without fixing, the areas for gluing 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 tapes based on butyl rubber

For right choice it is important to consider the type of window trim 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 means of insulation are used. For wooden windows installed in log cabins, natural aggregates are usually used - sphagnum, jute, linen 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 tasks 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 rooms - 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 single-sided adhesive layer and double-sided. A one-sided sticker is applied if the lena is mounted on side surface window frame. Double-sided tape gives an advantage in the choice of fasteners: on the frame or in the window opening. According to climatic versions, the tapes are also produced in two types - for areas with low winter temperatures - winter version ribbons, and for areas where temperatures do not fall below + 5⁰С - the summer version.

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

The main types of vapor barrier tapes:

PSUL, or pre-compressed sealing tape - used for finishing and vapor barrier of external joints, provides a tight connection between the window frame and outer wall. base material - butyl rubber, the thickness and elasticity of the tapes provide good insulation.
VS - vapor barrier tapes for sealing joints for dry finishing of slopes - made of plastic or drywall. gluing 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 the joints.
GPL - polyethylene foam tape, laminated on one side, with metal strips and a full-width adhesive layer.

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. 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, hygroscopicity is almost zero. The tapes are plastic and suitable for mounting on uneven surfaces. Metal lamination and the quality of the base polymer (polypropylene as a protective layer) determine the chemical resistance in both acidic and alkaline environment, and as a result - good durability of GPL tapes.

GPL tapes are produced in standard sizes width of window and door blocks, 9 in width; 12; 15; and 20 cm, in rolls of 15 m.

Features of installation of vapor barrier tapes

The minimum temperature for mounting tapes is + 10⁰С
The sticker of the tapes is carried out on the prepared surface - complete cleaning of all contaminants, dedusting and degreasing. Preparation is essential for correct operation vapor barrier
Marking lines for attaching vapor barrier tapes. Determine the position of the frame in the opening without fixing, mark the lines of the sticker of the tapes, then remove the frame and mount the tape according to the markup
Protective strips of paper are removed from the tapes immediately before final assembly ram
After gluing the tapes, the joint is filled with mounting foam
Tapes under the window sills are mounted last
If wet plaster is planned on the vapor barrier tape, then outer side tape must ensure adhesion with the solution. From the range of vapor barrier tapes it is possible to choose a material with the desired properties
Tapes are glued along the perimeters of the frames without breaks, in continuous stripes. Overlapping and overlapping of tapes is not needed, they are used at joints adhesive compositions recommended by manufacturers, or adhesive tape

The question of the need for vapor barrier windows is decided by each owner, based on the specific operating conditions of the windows. Budget options tape mounting is absolutely excluded. But many experts believe that the vapor barrier of windows is by no means reinsurance, but a real opportunity to increase the resource window systems and improve the microclimate in the premises, and savings in this case is not quite the right approach.

Salute, readers!

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

What battles sometimes flare up there!

So this time, on one of these forums, I managed to become a witness to disputes about the need to use vapor barrier tape.

One member of the forum, foaming at the mouth, argued that she was not needed and that it was good publicity stunt one of the Western companies, the other - explained why it is bad without it.

If you do not 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 good finish slopes and assembly seams provide decent window performance. In order for the window in your house to function well and for a long time, you should not miss such a moment as installing a vapor barrier tape.

The hermetic tapes used to isolate the installation seam from the vapors and moisture of the adjoining premises prevent condensate from escaping onto the slopes.

If you have a kitchen, a room with a pool or a sauna, then installing a vapor barrier tape on the windows is a must for you.

Varieties of vapor barrier tape

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

Also, vapor barrier tapes are classified according to weather periods:

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

The width of the tape also varies depending on the needs, which makes it possible to provide a reliable vapor barrier for joints of various sizes. When choosing vapor barrier tapes, keep in mind that its width should be about 45 mm more than the width of the mounting seam.

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

Vapor barrier tape can be butyl rubber, for tightness interpanel joints or to install door or window units.

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

To protect the installation seam from high humidity 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 inner and outer surfaces of the opening and frame from dirt, dust and other debris. The frame is inserted into the opening and is not temporarily fixed.
After gently mark the line on the frame for attaching the vapor barrier tape.
After carrying out the calculations and marking with 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 later attaches to the walls.

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

Useful advice!

Therefore, before finishing, moistening 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 concealed installation, then from above and on the sides the tape should be attached to the ends of the structure, and from below to the installation profile.

External heat-insulating tapes can be glued no earlier than the complete polymerization of the mounting foam.
Installation of 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 provide the necessary adhesion to this plaster layer.

In the event that the window quarter has gaps between the frame and the wall, a different technique is used: an uneven joint can be closed with a window flashing, and a vapor barrier tape can already be glued on it.

Installing a 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.

Installing the 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 mounting seam from the inside from moisture and prevents it from escaping from the seam to the surface of internal slopes.

For easy and secure fixation, the tape has two adhesive strips of glue and butyl, located on two different sides. It is recommended to apply along the entire perimeter of the window for the subsequent finishing of slopes in a dry way.

b) vapor-tight doubled sealing tape made of non-woven fabric coated with self-adhesive plastoelastic mass based on butyl rubber high degree stickiness.

A feature of butyl rubber tapes is their rather large weight. And, if we compare butyl rubber tapes and reinforced foil with the same width of 120 mm, it turns out that the reinforced foil tape is almost 5 times lighter than the 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 inner slope, and butyl rubber tapes have a tighter abutment and better adhesion to the wall opening.

To install the internal vapor barrier sealing tape, proceed as follows:

Cut the tape into pieces with a length equal to the width and length of the window +10 cm (for the formation corner connections). Docking of tapes along the length is allowed "overlapping", not less than ½ of the tape width.
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 fastened by means of a self-adhesive duplicated mounting strip in a taut state (tightly, without folds or swelling) to the outer surface of the box from the inside vertically and horizontally to the ceiling. The inner edge of the adhesive layer must match 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 sufficiently high resistance to low temperatures without loss of adhesive properties.

Lack of adhesion can occur if the acrylic adhesive strip is kept 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 the worker breathes, steam (moisture) is released, which partially condenses on the surface of the cold window block, which also reduces the adhesion of adhesive strips.

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

How to properly apply vapor barrier tape on PVC windows

Question: How to apply vapor barrier tape for pvc windows correctly and at what temperature?

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

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

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 ones at air temperatures below 0 degrees. The window tape should be chosen so wide that it is 45 millimeters wider than the width of the mounting joint. This will allow you to provide a reliable vapor barrier for the installation seams of your windows.

The very technology of installing windows and applying vapor barrier tape is as follows. We clean the opening from dirt and dust, install the window frame and, without fixing it, mark on the walls of the opening and on the window frame the fastening lines of the vapor barrier tape.

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

Useful advice!

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

Now you can assemble the window with sashes and install it thoroughly in its place. We install the vapor barrier tape on the window sill as a last resort.

Tape BM+ prevents condensation on the surface of internal slopes and protects the mounting foam from moisture from the room.

The tape has an adhesive layer across the entire width of the tape fastening, protected with release paper, on the one hand, and an adhesive strip, on the other side, for ease of installation.

The tape is supplied in rollers 25 meters long running in different widths.

Tape hydrovapor barrier (HPL).

Basis - the made foam polyethylene possessing high thermal insulation properties. Due to the closed cell structure, polyethylene foam has an extremely low hygroscopicity, i.e. practically does not absorb moisture.

Polyethylene foam gives the tape elasticity, which is necessary for sealing joints with various irregularities. The outer layer is a metallized polypropylene film.

Polypropylene film has a high mechanical strength and resistance to alkalis, acids and organic solvents, thanks to this, the reflective layer is reliably protected from oxidation and mechanical damage.

It is important!

In addition, polypropylene film is a good vapor barrier.

To prevent sticking of layers in a roll, the sticky layer is protected by a siliconized film.

Application: heat-, hydro-, vapor barrier of mounting joints and joints in various building structures - window and door blocks, metal products, concrete, wood, plastic, etc.

Hydro vapor barrier tape (GPL-S).

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

An additional adhesive strip is applied on the side of the film for ease of installation. Basis - the made foam polyethylene possessing high heat-insulating properties.

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

How to properly install windows?

Modern builders most often use mounting foam for installation. M O Window tape is applied together with sealant after the foam has dried. It is needed in order to protect the material from moisture, as well as to close possible gaps 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. There will be drafts, the windows will sweat a lot and freeze at the joints.

Why is vapor barrier used in plastic structures?

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

Workers must ensure that they comply with the following conditions:

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

Vapor barrier tape for is necessary to ensure the protection of the structure from water vapor.

In order for the vapor barrier not to interfere with the plastering, special tapes should be used, on top of which the room can be finished.

What should you know about sealing?

Most often, windows are fastened with special bolts and: this material simultaneously serves as a reliable retainer that allows 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 enters the foam begins to deteriorate over time, crumble and turn yellow, which negatively affects its properties.

Window tape is great for protecting foam. Even if you are going to use platbands that will protect the structure from weather conditions, and also be able to give the frame decorative look, before installing them, it is worth sticking the tape. It will help to make the insulation of high quality, while making the work not much more expensive.

The most inexpensive and easy-to-install vapor barrier for windows is a special tape that everyone can handle with a sticker.

"Robiband" is a trademark under whose name high-quality component materials and hermetic products for windows are produced. Robiband window tapes allow you to quickly, reliably and efficiently seal window assembly joints, seams adjacent to sheet materials roofs, as well as protect heat-insulating materials from the negative effects of moisture and provide vapor barrier.

For convenience, practicality and efficiency, vapor barrier tapes are produced in rolls of different widths. Window openings, after the frames are installed, may have different way finishes, therefore robiband tapes are produced both for dry finishing and for further painting and plastering.

basis vapor barrier tape is an aluminum foil reinforced with a synthetic thread with an adhesive layer (can be one- or two-sided), thanks to which you can easily, accurately and quickly fix the tape. For better adhesion, one side of the tape is reinforced nonwoven fabric. It protects the insulation from excessive saturation with moisture on the one hand and at the same time does not allow moisture from the mounting joints to pass into the inside of the window slopes.

It is only necessary to prepare the surface for applying the tape if the surface begins to crumble or absorb a little. In other situations, before applying the tape, it will be enough just to remove construction dust and other contamination from joints and crevices.
