Tapes for installation of windows according to GOST. Using tape to insulate windows Internal vapor barrier tape for windows

Replacing windows in a residential or commercial space is always accompanied by the protection of 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 polyurethane foam. This material has excellent sound and heat insulation qualities. However, with insufficient or incorrect protection under the influence of moisture and ultraviolet radiation, the foam begins to collapse and lose its original properties.

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

The structure of vapor barrier for a plastic window is shown

What should the vapor barrier be like?

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

To protect joints use:

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

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

The choice of vapor barrier should be made taking into account subsequent finishing. So there is material for dry construction (plasterboard, plastic), wet plaster, there is separately for protecting joints wooden windows V wooden houses, for internal and external 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 seams between the window and the wall of the house are sealed efficiently. Also, a vapor barrier for windows can have either one adhesive side or two.

Vapor barriers for PVC windows are distinguished by seasonal periods:

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

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

If you don’t do a vapor barrier and slopes, there may be fungus

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

Installation of vapor barrier for windows

Below are general rules installation of vapor barrier for PVC windows, since for each a separate type tapes may have their own characteristics:

1. The window frame and opening are cleaned of dirt and dust.
2. The window is inserted into the opening without fixation; 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. The outer tapes are glued only after the mounting foam has completely dried. 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 that comply with all moisture-permeable characteristics.

Where can I buy? Prices

You can buy vapor barriers for PVC windows at any hardware store. If you have to replace windows in your home, consult with repairmen which vapor barrier is best for you to choose, taking into account the final finishing of the walls.

True professionals will give you practical recommendations. But, if you come across “experts” who insist that using vapor barriers for windows is unnecessary, kick them to the curb. Someone's incompetence can later bring you a lot of problems with dampness and drafts.

It can improve the quality characteristics of the structure, which extends its service life. On sale you can find tapes that have an adhesive strip on one or both sides. It is designed for fixing the tape to the window and wall. Among other things, such materials are classified according to temperature characteristics during operation.

The first variety is suitable for summer period and can be used in a temperature range from +5 to +35°C, while products intended for winter can withstand temperatures below zero degrees. The width of such a strip can vary depending on the tasks, which allows it to provide vapor barrier to seams different sizes. When choosing a vapor barrier tape, you must take into account that its width should be 45 mm larger than the installation seam.

general description

The described outdoor installation tapes may consist of foam materials and are required for and may be used in conjunction with plaster mortar, which increases vapor barrier characteristics. There is a vapor barrier tape for windows on sale, the characteristics, photos of which are presented in the article. This material may be based on butyl rubber, which is intended for sealing joints and installation on windows and windows. The product consists of non-woven fabric, during installation it is primed, at the next stage it is covered with plaster, and at the final stage it is painted. This type has a self-adhesive layer. If you need a vapor barrier tape that will be used for high humidity, then the material should be installed for dry finishing of slopes, using a metalized variety.

Characteristics of foil vapor barrier tape

Foil hydro-steam and thermal insulation tape is glued to clean, dry and pre-degreased surfaces. The material itself is supplied in boxes whose dimensions are 420x420x600 mm. It should not be used at temperatures below +10°C. The tapes are based on polyethylene foam, which is laminated and metalized with polypropylene film on one side, while on the other there is a waterproof adhesive layer that reliably ensures fastening of the material to concrete, brick, metal, plastic and wooden structures.

It is based on a material that consists of a closed cellular structure; it has low hygroscopicity and almost does not absorb moisture. Elasticity is ensured thanks to polyethylene foam, which guarantees sealing of seams with varying degrees of unevenness. High mechanical strength was achieved thanks to the presence of polypropylene film, which is resistant to alkalis, organic solvents and acids. The reflective layer is protected from mechanical damage and oxidation. Sticky layer consists of a water-resistant adhesive, which is created on the basis of synthetic rubber. It has improved adhesion properties different materials, which allows you to use the tape without preliminary preparation surfaces.

For reference

You don’t have to worry about the vapor barrier tape sticking together in the roll, since there is a protective siliconized layer on its surface. This type of steam-hydro-thermal insulation is used for seams, assemblies and connections of various building structures, including when installing window blocks, wood, metal, plastic and concrete products.

Material sizes

The film thickness is 20 microns, while the length is 15 m, and the width can vary from 90 to 200 mm. Intermediate values ​​are 120 and 150 mm.

Specifications

Vapor barrier tape for windows has a high coefficient of thermal reflection, which reaches 95%. The thermal conductivity coefficient is very small, and at 20°C it is in the range of 0.038-0.051 W/m °C. The heat absorption coefficient during the day reaches 0.48 W/(m 2 °C). Thermal resistance equals 0.031 °C/W, which is true for one millimeter of thickness. Professionals are sometimes also interested in such characteristics as specific heat. In the case of the one described, this parameter is 1.95 kJ/kg °C.

Under a load within 2-5 kPa, the dynamic modulus of elasticity can vary from 0.26 to 0.6 MPa. Vapor barrier tape for windows has another significant advantage, which is expressed in the ability to absorb extraneous noise. Thus, the sound absorption is 32 dB. The material belongs to the flammability group G2, smoke-forming ability - D3. The density of the material can be equal to 50 and 80 kg/m3.

Features of installing sealing tape

Vapor barrier tape for windows, specifications which were presented above, must be installed according to the design developed for of this material algorithm. For internal sealing of the seam, duplicated vapor barrier tape based on aluminum foil. For reliable and easy fixation, there are adhesive strips on it, which are located on both sides. The tape should be installed around the entire perimeter of the window, and then covered with slopes that are installed using a dry method.

To install the internal vapor barrier tape at the first stage, it should be cut into separate pieces, the length of which will be equal to the width and length of the window. To these values ​​you need to add 10 cm, which will go to corner connections. The length of the tape is joined with an overlap, the width of which should be approximately 1/2 the width of the material.

Work methodology

Vapor barrier tape for PVC windows, the use of which is described in detail in the article, at the next stage is freed from the protective paper on the side of the duplicated strip. Now the material can be glued to the frame profile. This must be done under tension, and the inner edge of the adhesive layer must coincide with the inner edge of the frame. The protective layer that is on the butyl rubber coating should not be removed at this stage.

To ensure that the adhesion of the adhesive strips is not reduced, the structure must be kept open for a shorter period of time, and before gluing, the surface of the window must be wiped with a soft rag or paper napkin.

Conclusion

Vapor barrier tape for windows, the density of which was mentioned above, should be installed in one piece, with breaks at flat surfaces there shouldn't be. On final stage you need to install the tape on the window sill, and then assemble the window with sashes.

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

How to install windows correctly?

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

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

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

What is vapor barrier used for in plastic structures?

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

It is necessary to ensure that workers comply with the following conditions:

• Interior installation gap should be filled with foam thicker than the outer one.
• The system must be three-layer. The first layer on the street side protects the entire pie from weather conditions, the middle layer is responsible for thermal insulation, and the inner layer protects against condensation.

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

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

What should you know about sealing?

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

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

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

Helpful information

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

Mounting tapes for windows

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

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

Mounting foam for windows

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

Buy PSUL in Moscow

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

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

About insulation

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

Most often they are the following:

1. Wooden windows

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

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

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

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

1. Plastic windows

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

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

• violation of window installation technology;

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

• factory defect of window design;

• mechanical damage to structural elements.

Types of insulating tapes

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

• no annual replacement required;

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

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

• no traces of adhesive remain on the frame;

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

But this method of insulation also has disadvantages:

• after gluing, you cannot open the window sashes;

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

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

1. Pasting

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

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

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

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

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

• high compression ratio;

• the frame does not collapse in places of insulation;

• low cost;

• high protection efficiency.

Such tapes have negative qualities:

• insufficient efficiency for large gaps;

• short service life. Effective during one winter season;

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

• low resistance to water.

Important!

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

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

1. Sealing

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

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

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

The following qualities are considered advantages:

• gaps up to 0.7 cm are blocked;

• withstands any temperature changes;

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

• the use of the window is not limited;

• affordable price.

But most of the disadvantages relate to adhesive tapes:

• not suitable for all window designs;

• when temperature changes, the adhesive layer is destroyed;

• with frequent deformations, peeling occurs in the glued places;

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

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

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

By material

Main advantages:

• low cost;

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

There are also disadvantages:

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

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

Unfortunately, such tapes are rarely used for window insulation, as they become more expensive window design up to 15 %.

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

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

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

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

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

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

By manufacturer

In construction stores you can find tapes from different manufacturers.

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

• Russia - Profitrast, Economy, Zubr.

• Germany - KIMTEC, Deventer.

• Poland - Sanok.

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

By cost

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

Because for standard window About 5 meters of self-adhesive insulation is needed, then most often it is purchased at retail.

The price range is very wide.

Behind linear 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 windows for insulation

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

The main stages are as follows:

1. Everything is removed from the windowsill. The 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. The glass is carefully inspected. Wooden windows may have cracked glass. They must be replaced as they are a source of heat loss.

1. Grooves are prepared for the sealing tape. They should not contain old tape, dirt or paint.

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

Insulation with adhesive tape

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

1. Plastic windows

Insulation is performed in the following sequence:

• pre-removed old insulation is used, firstly, to purchase similar material, and secondly, to pre-cut the old material to size.

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

More details in our video:

Important!

1. The pasted tape should not have many tears.

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

1. Wooden windows

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

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

• cut foam rubber is placed between the frames;

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

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

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

Insulation with sealing tape

1. Plastic windows

Typically, plastic windows lose heat for two reasons:

• breakdown of fittings;
• seal wear.

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

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

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

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

Important!

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

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

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

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

1. Wooden windows

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

• there is no need for annual window insulation;

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

• the service life of the frames increases;

• high degree of protection from dust and street noise.

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

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

Installation is performed in the following sequence:

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

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

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