Foil tape for windows. Installation of vapor barrier tape when installing pvc windows. Installation is carried out in the following sequence

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 most weak point throughout the 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. Description of characteristics assembly 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:

  1. The middle layer - the main one - provides heat and sound insulation due to the porous structure.
  2. The outer layer protects against moisture coming from the street (it removes it) and from UV rays.
  3. The inner layer is a vapor barrier. In fact, it traps heat in the house and does not give steam that accumulates in inner space rooms, penetrate 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, to improve heat and soundproofing 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:

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

Tape types

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

Production material

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

Available 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. The 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.

  1. The window opening is wiped with a dry cloth and the window structure is pre-installed. In the process, the future location is marked vapor barrier tape PSUL.
  2. 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.
  3. Tape for slopes is glued to the side profiles and the top one. leave an overlap of about 10 cm.
  4. Install the window. Foam the seam.
  5. Assembly seam with outside covered with diffusion tape.
  6. Before installing the tide, PSUL is glued along its lower surface.
  7. On the seam at the bottom of the box with inside fix the metallized vapor barrier tape.
  8. The tape on the window sill is glued last.

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 about 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 window frame and a wall through which cold air will enter the room. There will be drafts, the windows will sweat a lot and freeze at the joints.

See the link for window installation steps and common mistakes during their installation.

When building a private house, you need to think in advance, the height will be, which ones will be more practical and look better.

Modern builders will often use to install doors and plastic windows. Read on the website for advice from professionals on how to choose it

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.

Care must be taken to ensure that workers without fail fulfilled 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 gets in, 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.

Salute, readers!

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

What battles sometimes flare up there!

So this time, at one of these forums, I managed to witness 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.

Welcome!

Vapor barrier tapes for windows good finish slopes and assembly seams will provide worthy characteristics of a window. 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 the 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 of the seams. 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, good sealing materials with plaster mortar, which will provide the required vapor barrier of the outer layer).

The vapor barrier tape can be butyl rubber, for tightness of interpanel joints or for installing door or window blocks.

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

For protection against high humidity mounting 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 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 stripes with 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 complete polymerization polyurethane 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.

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

a) vapor barrier tape (duplicated) based on aluminum foil, laminated with a 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 the 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 is made of a non-woven fabric coated with a self-adhesive plastoelastic mass based on high-tack butyl rubber.

The peculiarity of butyl rubber tapes is that they are quite big weight. And, if we 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 them easier to work with 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, while butyl rubber tapes have a tighter abutment and better adhesion to the wall opening.

To install an internal vapor barrier sealing tape, you need to do the following:

  1. 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.
  2. 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.
  3. 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 decreases 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 to a minimum. possible time and also wipe the surface of the window block with a dry cloth or paper napkin immediately before gluing tapes to it.

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

Answer: The installation of vapor barrier tapes on plastic windows is carried out as usual in those rooms where there is high humidity - a kitchen, a bathhouse, a 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 it on the walls of the opening and on window frame lines for fastening 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.

Greetings!

Today we will touch on a controversial topic. Do I need a vapor barrier tape when installing PVC windows?

I think you will be interested to know what it is and why it is needed.

Vapor barrier tapes are designed to improve performance characteristics window structures. The effect of their installation is comparable to quality finish slopes or laying assembly seams. The installation of such tapes will help extend the functioning of windows; in no case should you refuse to install it.
Sealed tapes provide insulation of the installation seam from excess moisture and steam, they prevent the movement of condensate to the slopes window construction. Installation of such a tape is necessary if there is a kitchen, a bath or a room with a pool.

Varieties of vapor barrier tape

There are two main types of material: with one and two adhesive surfaces.

Tape with two adhesive surfaces one side attached to the wall and the other to the window.

There is a classification of tapes on a seasonal basis:

  • for summer, withstand temperatures - 5-35 degrees;
  • for winter, suitable for temperatures below 0.

The width of the tape depends on design features profile, a wide range of allows you to choose the option for seams different sizes. When choosing a tape, it must be taken into account that its width should be approximately 45 mm greater than the width of the installation seam.

The composition of the tape for outdoor use includes foam materials, in this case sealing compounds with plaster mortar are used, providing the necessary level of vapor barrier.

Vapor barrier tapes can be made from butyl rubber, they are used for sealing interpanel joints, as well as when installing windows and doors.
The composition of this tape includes a non-woven fabric, during installation it undergoes priming, plastering and painting, this type also belongs to the group of self-adhesive.

There are also metallized vapor barrier tapes on the market, they are designed to protect the mounting seam of slopes for dry finishing from moisture.

General information on the installation of vapor barrier tape

The process can be divided into the following stages of work:

  • prepare the opening, clean it of dust, dirt and debris, insert the frame into the opening, temporarily not fixing it;
  • on the frame, carefully mark the line for mounting the tape;
  • make calculations, mark with a window, stick internal vapor barrier tapes on the removed frame (the protective paper strip covering the adhesive must remain in place, it should not be removed.)

In accordance with the rules, the installation of the vapor barrier tape is carried out before the seam is foamed.
Before finishing, moistening and filling with mounting foam, the protective paper strips must be removed.

This is necessary to maintain the adhesive properties of the tape. When flush mounting is carried out from below, the strip is attached to the installation profile, on the sides and top to the ends of the structure.

The following features must be taken into account:

  • external tapes are glued after complete polymerization of the mounting foam;
  • installation of a vapor barrier strip under the window sill is carried out at the final stage;
  • when installing a vapor barrier strip under a layer of plaster, special requirements are imposed on the outer coating of the tape, it must provide the necessary level of adhesion between the surfaces to be joined.

If there are gaps between the wall and the frame of the window quarter, a different technique is used: the uneven joint must be closed with a special flashing for windows, after which a vapor barrier tape is glued.
The vapor barrier tape is glued around the entire perimeter of the window opening in a continuous layer.
It should also be borne in mind that the use of finishing building materials in conjunction with a vapor barrier tape is recommended only if certain moisture permeability characteristics are observed.

Foil self-adhesive waterproofing tape

Self-adhesive strip GPL allows you to solve problems associated with steam, hydro and thermal insulation of joints, assembly seams, junctions and joints in a wide variety of building structures - door and window blocks, plastic, concrete and metal products.

The vapor barrier layer provides the necessary level of waterproofing, which prevents the formation of mold, fungi and spores, as a result, the life of any structure is increased.

Advantages:

  • significant reduction in heat loss;
  • significant reduction in energy consumption;
  • ease of installation, achieved due to the adhesive layer;
  • ensuring secure fastening of the film on building materials all types.

GPL - foil self-adhesive hydro-steam and heat-insulating tape(width 90,120,150,200 mm, supplied in boxes with dimensions 420x420x600 mm). The choice of width depends on the design features of the window profile.

Installation steps:

  • clean, dry and degrease the treated surfaces, unwind the roll, cut the tape into pieces of the required size;
  • after removing the protective film, stick the film on the surface, pressing firmly with your hands and without stretching, smooth it with a roller, avoiding the formation of air bubbles.

Installing the internal vapor barrier sealing tape

For internal sealing of the assembly seam, a vapor barrier (duplicated) strip is used.

A vapor barrier (duplicated) strip, made on the basis of aluminum foil laminated with a non-woven fabric, provides the necessary level of moisture insulation of the assembly seam, and is a reliable barrier to moisture escaping to the surface of internal slopes.

Two adhesive strips of butyl and glue located on different sides allow for easy and reliable fixation. It is recommended to stick the tape around the entire perimeter of the window structure for finishing the slopes using the dry method. which will be carried out in the next step.

In the production of a vapor-tight doubled sealing strip, a non-woven fabric is used, covered with a self-adhesive plastoelastic mass made on the basis of sticky butyl rubber.
The main feature of butyl rubber strips is their heavy weight. When comparing butyl rubber tape and reinforced foil of the same width of 120 mm, it turns out that the reinforced foil is almost five times lighter.

The low weight of the foil greatly simplifies the installation process, which reduces transportation costs when transporting material over long distances.

Vapor barrier tapes with adhesive strips made on the basis of reinforced foil have high adhesive properties only if the surface of the inner slope is well cleaned and degreased. Butyl rubber strips are distinguished by better adhesion and a tighter abutment to the wall opening. All these characteristics must be taken into account when choosing one or another option, if necessary, you can always consult a specialist.

Installation steps for the internal vapor barrier sealing tape:

  • cut the material into pieces, taking into account the length and width of the window structure (for corner joints), the joining of the strips along the length is overlapped, at least half of its width;
  • remove the protective paper from the duplicated strip, stick it on the outside of the frame;
  • the installation of the strip is carried out using a self-adhesive mounting strip in a taut state (without blisters and folds, maximum) to the outer surface of the window frame from the inside along the ceiling horizontally and vertically.

The inner edge of the adhesive surface and the inner edge of the frame must exactly match, the protective tape is not removed at this stage.

The adhesive strip is highly resistant to cold temperatures while maintaining adhesive properties.

Adhesion deterioration can be affected by prolonged cold exposure of the acrylic adhesive tape with the release paper removed.

Working with cold window structures can also have a negative effect on adhesion, since when workers breathe, steam is released from the mouth, partially condensing on the surface of the block, as a result, the adhesion of the adhesive surface is reduced.

In order to prevent this phenomenon, the interval between the removal of the release paper and the actual application of the tape should be as short as possible. Before sticking the tape, it is also necessary to wipe the surface of the window block with a paper towel or dry rag.

Proper application on PVC windows

Question: How to use a vapor barrier tape for PVC window structures correctly, what should be the temperature?
Answer: Installation of vapor barrier tapes on plastic window structures is carried out in the usual way in rooms with high level humidity (pool, sauna, kitchen).

The material provides protection of the installation seam from the penetration of steam and moisture emanating from the room, the tape thus prevents the condensate from escaping onto the window slopes. The vapor barrier strip may have one or two adhesive surfaces.
Tape with two adhesive surfaces is conveniently attached to the slopes and the window. All vapor barrier tapes are divided into winter and summer, the choice depends on the season and weather conditions.

Summer tapes are designed for operation at a temperature of 5-35 degrees, winter ones have proven themselves well in conditions below zero. Width plays an important role when choosing a tape, it should be 45 mm larger than the width of the installation seam. Compliance with this condition will help to achieve required level vapor barrier.

The technology for installing windows and gluing vapor barrier tape consists of several stages.

Necessary:

  • clean the window opening from dust and dirt, install the frame without fixing it, mark the installation lines of the vapor barrier tape on the frame and the walls of the opening;
  • pull the frame out of the opening, stick the tape on it without removing the protective strip from the area intended for sticking to the wall.

Installation of vapor barrier tape on plastic window produced in one piece, breaks are unacceptable.

At the next stage - the assembly of the window structure with sashes and the capital installation in the opening. At the final stage, the vapor barrier strip is glued to the window sill.

window tape

The assortment includes big choice high quality window tapes, in various sizes and required quantity. Indoor and outdoor window tape is widely used in a wide variety of construction and installation fields.

Window tape is a reliable connecting element, on the entire surface of which small holes are made in accordance with waterproofing standards. Wide selection sizes allows you to choose the option for a variety of designs.

Premium Window Tapes

Window tape is a reliable connecting element, on the entire surface of which there are small holes.

In the manufacture of perforated tape, polyethylene foam is used High Quality, the scope of use is determined by the manufacturing technology. One of the areas of application is the installation of ventilation elements.

Effective filtration of dirt and dust from the outside is achieved through holes through which accumulated condensate also escapes.

Thanks to these features, a unique microclimate is created in the room, price for mounting tape while not very high, which is one of the advantages of the material.
The advantages of window tapes can also be attributed to the acceleration of the pace of construction, they are indispensable when fastening parts with different expansion coefficients.

The advantage of double-sided window tapes is elevated level elasticity, which is important at temperature extremes.

Vapor-permeable diffusion tapes are also produced, which are used to create effective ventilation with excellent moisture resistance.

Diffuse tape made of artificial membrane material is indispensable in the process of waterproofing assembly seams and joints. The tape can have one or two adhesive strips; when choosing, it is necessary to take into account the tasks of construction and the features of the window structure. One of the strips is attached to a translucent structure, the other - to a slope or wall surface.
A wide range of sizes allows you to quickly select desired option for any building structure. Window tapes are equally well suited for both internal and external insulation during installation.

The innovative technology involves the implementation of insulation in several layers: that is why there is a distinction between external and internal window tapes.

Inner window tape made from flexible material, has adhesive strips, it is specially designed to protect the seam from steam and moisture from the inside.
While creating outer tape the standards for waterproofing the outer side of the seam were taken into account.

Both types of material allow you to achieve the required level of moisture insulation while maintaining vapor permeability and protecting the structure from condensate.

Vapor barrier tapes for windows, as well as good finishing of slopes and installation seams, will 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

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.

Installation of vapor barrier tape

Same way vapor barrier tapes are classified according to weather periods:

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

Tape width 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.

Tapes 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).

The vapor barrier tape can be butyl rubber, for tightness of interpanel joints or for installation of door or window blocks. This tape contains a non-woven fabric. During installation, it is primed, plastered and painted. This type is also self-adhesive.

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

Installed vapor barrier tape

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. 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 conducting hidden installation, then the tape should be attached to the ends of the structure from above and on the sides, 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 that case if the window quarter with 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 onto 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.
