Installation of vapor barrier tape when installing pvc windows. Tapes for mounting windows according to GOST Vapor-permeable tape

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.

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.

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

Is it worth it to spend money on protecting window seams?

When installing a window in an opening, remember that its service life is related to how competent the installation will be. Even the most quality constructions will not be used for a long time if the installation is incorrect. 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 a few important points:

• With inside rooms we make a denser layer of mounting solution (for example, foam).
• For quality termination we use three-layer protection for all gaps - 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 of the heat-insulating layer from condensate, which is present not only in the bathroom, but also in 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 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. 1. insulates moisture;
2. 2. it is spent economically, practically without waste;
3. 3. does not emit toxic substances;
4. 4. easy to stick;
5. 5. has a long service life.

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 treated surface, the tapes are produced various sizes, thanks to which you can isolate any seams. When choosing a material, keep in mind that it should exceed the gap by 4.5 cm in width. To work with outside buildings are suitable for foam tapes, 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. Inside it is laid non-woven layer. After gluing, such a strip is primed, plastered, wallpapered or painted. There is a full-butyl vapor barrier tape made according to the Robiband system. It provides more quality processing 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 different widths. When selecting material, add 45 mm to the width of the seam.

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

We understand 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 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 - 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 made from polyethylene foam. 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.

How to stick insulation - we work without errors

The vapor barrier material not only provides protection against moisture, but also has an alternative property when correct gluing- noise reduction. Application vapor barrier tape the seams are made 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. 1. Clean the window opening from dirt, dust and debris.
2. 2. Before installation, remove the PVC window and wipe it with a dry cloth.
3. 3. Put the structure in place and mark on the frame and wall where the tape will be attached.
4. 4. The tape is attached to window frame before applying foam at the seam.
5. 5. Remove the structure and stick a vapor barrier on its surface around the perimeter.
6. 6. Before installing the window in place, remove the remaining protective film from the adhesive surface.
7. 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, you need to glue after polyurethane foam 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 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 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.

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

About warming

The microclimate of the room depends on the windows. Because of the uninsulated windows, the glass fogs up, cracks and fungus appear on the slopes, there is a constant draft and street noise. In order to effectively insulate windows, it is necessary to determine the causes of low thermal insulation.

Most often they are the following:

1. Wooden windows

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

• Previously, glass was attached to the frame with a special putty. Over time, it dries out and crumbles;

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

• the sashes are deformed and loosely held on the frame.

1. Plastic windows

It is erroneously believed that such windows are quite tight, so they do not need insulation. Unfortunately, after a few years, the seal is destroyed, and insulation is indispensable.

There are other reasons why you need to deal with plastic windows:

• violation of window installation technology;

• skew window construction due to shrinkage of the house;

• factory defect of the window structure;

• mechanical damage to structural elements.

Varieties of insulation tapes

The widespread use of tapes for window insulation is due to a number of reasons:

• no annual replacement required

• warming is carried out in a short time on their own;

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

• there are no traces of adhesive on the frame;

• no diffusion of the adhesive layer with the frame paint.

But this method of insulation also has disadvantages:

• after gluing, you can not open the window sashes;

• low-quality or poorly glued tape lags behind the frame small areas.

Hardware stores offer two types of tapes, which differ in the way they are installed.

1. pasting

Tapes of this type have a wide grip. Adhesive composition applied during manufacture (self-adhesive type) or during installation work.

To create a 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. So that the insulation does not stand out against the background of the window, dyes are added: black, brown, white.

Typically, the packaging indicates the size of the gap that the tape closes. Popular options with sizes 3 - 7 mm.

Foam tapes were the first to be used. Their popularity is due to 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. Effectively operate during one winter season;

• for cheap models, the adhesive tape is poorly fixed;

• low water resistance.

Important!

More convenient to use for insulation self-adhesive tapes on the foam.

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

1. Sealing

Tapes of this type have a hollow tubular shape, which is why heat is retained. The material used is 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 to be advantages:

• gaps up to 0.7 cm are blocked;

• any temperature fluctuations are maintained;

• it is possible to choose the color to match the frame color;

• the use of the window is not limited;

• affordable cost.

But most of the disadvantages relate to adhesive tapes:

• not suitable for all window designs;

• when the temperature changes, the adhesive layer is destroyed;

• with frequent deformations, delamination occurs in glued places;

• The foam tape gets wet quickly 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, the tape is selected according to three indicators.

By material

Main advantages:

• low cost;

• high elasticity, allowing to close cracks 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%.

1. Rubber― it is used for production of two kinds of tapes: self-adhesive and sealing.

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

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

1. Polyurethane foam (PPE)― porous material from the made foam polyethylene.

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

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

Manufacturers

In hardware stores there are tapes from different manufacturers.

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

• Russia ― Profitrast, Ekon, Zubr.

• Germany - KIMTEC, Deventer.

• Poland - Sanok.

Domestic manufacturers, as a rule, work according to European technologies and produce quality material no worse than foreign samples. At the same time, although German and Polish tapes are more expensive, they last longer.

By cost

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

Because for standard window you need about 5 meters of self-adhesive insulation, then retail purchases are most often made.

The price range is very wide.

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

Features of preparing a window for insulation

Preparing a window for insulation with tape is almost the same as preparing for other heaters. At the same time, there are some peculiarities.

The main steps are:

1. Everything is removed from the windowsill. Blinds are removed from the window.

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

1. Glasses are carefully examined. At wooden windows glasses are cracked. They must be replaced, as they are a source of heat loss.

1. For sealing tape grooves are being prepared. They should be free of old tape, dirt and paint.

1. Before starting work, they are determined with places where cold air comes from from the street. They warm up first. Weak spots- these are sashes, slopes, window sills.

Insulation with adhesive tape

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

1. Plastic windows

Warming is carried out in the following sequence:

• pre-filmed old insulation it is used, firstly, for the acquisition of similar material, and secondly, for preliminary cutting to the dimensions of the old material.

• gluing starts from the top of the window. As you move, the protective layer is removed in small sections, and the tape is pressed tightly.

More in our video:

Important!

1. The pasted tape should not have many gaps.

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

1. Wooden windows

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

• strips of foam rubber are cut along the window opening;

• chopped foam rubber is placed between the frames;

• the tape is cut to the size of the window;

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

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

Insulation with sealing tape

1. Plastic windows

Typically, plastic windows lose heat for two reasons:

• equipment failure;
• seal wear.

Proper 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 it depends on 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 each meter, 1 centimeter of material;

• the tape is pressed with a spatula in the groove, and at the same time, the pasting strips are removed in small sections.

Important!

1. In the corners of the frame, the tape is butt-jointed only.

2. To prevent impregnation, the tape does not shrink more than the allowable value.

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

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

1. Wooden windows

The Swedish method of warming such windows using the 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 violated;

• increases the service life of the frames;

• high degree of protection against 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 carried out in the following sequence:

• the sashes are removed from the hinges and inspected. Decayed areas are identified, and then restored;

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

If you choose the right one, then the insulation will quickly pay off, and the apartment will always be warm and comfortable.

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 mounting seam from excess moisture and steam, they prevent the condensate from moving to the slopes of the window structure. 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, wide range of allows you to choose the option for seams of 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 sealants are used plaster mortar providing the required 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.
This tape contains nonwoven fabric, during the installation process, it undergoes priming, plastering and painting, given type also belongs to the self-adhesive group.

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.

Information about the self-adhesive sealing waterproofing tape in the video:

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, protective paper stripes must be removed.

This is necessary to maintain the adhesive properties of the tape. When conducting concealed installation From below, the strip is attached to the installation profile, on the sides and from above 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.

Works should be carried out at a temperature not lower than +10°C.

Self-adhesive vapor-, hydro-, heat-insulating tapes consist of foamed laminated polyethylene, on one side a layer of metallized polypropylene film is applied. Special waterproof adhesive on the other hand provides secure fastening material on structures made of metal, brick, concrete, wood, plastic, etc.

Since the tape is based on foamed polyethylene, which has excellent thermal insulation characteristics, the closed cell structure provides an extremely low level of hygroscopicity, which guarantees a high level of moisture resistance.

Polyethylene foam gives the film elasticity, which is very important when sealing joints with irregularities. Metallized polypropylene tape is designed to finish the outer layer.
The advantages of polypropylene film include a high level mechanical strength, the material is also resistant to solvents organic origin, acids and alkalis. Thereby ensured reliable protection reflective layer from damage and oxidation.

Polypropylene film also has good vapor barrier properties.

The adhesive layer is a waterproof artificial rubber adhesive with increased adhesion to different materials, which allows the use of vapor barrier strips without surface preparation.
Siliconized film protects the adhesive layer from sticking in the roll.

Installing the internal vapor barrier sealing tape

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

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

Located on different sides two adhesive strips of butyl and glue allow easy and secure 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 connections), the joining of the strips along the length is carried out with an overlap, 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, as much as possible) 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, you must also wipe the surface of the window unit paper napkin or dry cloth.

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, high quality polyethylene foam is used, 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 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.

I hope that this article has helped you understand new window installation technologies and convinced you of the need to use vapor barrier tape.

Replacing windows in a residential or commercial space is always accompanied by protecting the weakest components of the structure: the seams between the frame and the wall. It is produced by filling the space between the window opening and the frame using mounting foam. This material has excellent sound and heat insulation qualities. However, with insufficient or incorrect protection under the influence of moisture and ultraviolet, the foam begins to break down and lose its original properties.

To avoid this, it is necessary to take measures to seal the seams and protect the filler. To do this, waterproofing is used from the outside, which prevents natural precipitation from entering the porous insulation, while from the inside, a vapor barrier is used for PVC windows, which protects the foam from the effects of water vapor.

What should be the vapor barrier?

Vapor barrier prevents moisture from the air in the room from being absorbed into the thermal insulation material. The coefficient of vapor permeability of the vapor barrier of internal seams for PVC windows should be no more than 0.01 mg / (m * h * Pa).

To protect the joints use:

• silicone;
• backing cords;
• fiefs PSUL;
• butyl rubber tapes;
• reinforced foil.

PSUL tapes are designed to create an assembly seam with natural ventilation.

The choice of vapor barrier should be made taking into account the subsequent finishing. So there is a material for dry construction (drywall, plastic), wet plaster, there is a separate one for protecting the joints of wooden windows in wooden houses, for indoor and outdoor use.

The tape can be either single or double-adhesive

Butyl rubber tapes are similar to self-adhesive foam rubber, but with a protective impregnation. With their help, all the seams between the window and the wall of the house are qualitatively sealed. Also, a vapor barrier for windows can have either one adhesive side or two.

There are vapor barriers for PVC windows by seasonal periods:

1. warm season with air temperature from 5 to 35 degrees above zero;
2. winter period with temperatures below zero.

Vapor barrier prevents the destruction of the mounting foam under the influence of moisture, prevents the appearance of damp corners in window opening, the appearance of fungus and drafts.

If you do not do vapor barrier and slopes - there may be a fungus

It should be noted that the price of vapor barrier for PVC windows is absolutely adequate and affordable for everyone. Very small costs for hydro and vapor barrier will increase the life of windows, and protect the house from drafts and mold in the corners.

Installation of vapor barrier for windows

The following are general rules installation of vapor barrier for PVC windows, as for each separate species tapes may have their own characteristics:

1. The window frame and opening are cleaned of dirt and dust.
2. The window without fixing is inserted into the opening, the places where the vapor barrier is attached are marked on the plastic.
3. The window is removed and a vapor barrier is glued to the marked places.

Concealed installation is carried out before the voids are foamed. External tapes are glued only after the mounting foam is completely dry. In any case, the vapor barrier tape is glued to the window in a continuous layer.

Do not forget that the choice of tape largely depends on the type of subsequent finishing. It is very important to use materials in compliance with all moisture-permeable characteristics.

Where can I buy? Prices

You can buy vapor barrier for PVC windows in any hardware store. If you have to deal with the replacement of windows in your house, consult with repairmen which vapor barrier is best for you to choose, taking into account the final wall decoration.

Real professionals will give you good advice. But, if you come across "specialists" who assure you of the uselessness of using vapor barrier for windows, drive them into the neck. Someone's incompetence can then bring you a lot of problems with dampness and drafts.
