Types of tapes for PVC windows, selection criteria and average price in the Russian Federation

High-quality glazing requires serious consideration and is impossible without proper insulation of the gap between the opening and the window. Often, organizations that install translucent structures limit themselves to traditional polyurethane foam, which is subsequently covered with plaster or other finishing materials. This approach has proven itself relatively well and in some cases does not cause any complaints from the consumer throughout the entire service life of the window.

However, glazing with one level of sealing of the opening does not meet the state requirements for the quality of services or goods provided, that is, GOST. To comply with these requirements, additional insulation is required at the junction of the window and the opening both from the street side and from the room side. Such insulation is ensured using special mounting tapes.

Scheme for using mounting tapes on windows

View from above

Mounting tape for windows is a self-adhesive material on a polymer or fabric basis, designed for additional sealing of window or door openings.

Types of vapor barrier tape

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

A tape with two adhesive surfaces, one side is attached to the wall and the other to the window.

There is a classification of tapes based on seasonality:

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

The width of the tape depends on the structural features of the profile; a wide range allows you to choose an option for seams of different sizes. When choosing a tape, it is necessary to take into account that its width should be approximately 45 mm greater than the width of the assembly seam.

The tape for exterior work includes foam materials; in this case, sealing compounds with plaster mortar are used to provide the required level of vapor barrier.

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

Metallized vapor barrier tapes are also available on the market; they are designed to protect the installation seam of slopes for dry finishing from moisture.

Criterias of choice

When choosing a tape for installing PVC windows, it is important to purchase the right type of material, based on the following principles :

• Considering that the material is used both to fix the window and to seal the gap after installation, it is important to choose the right tape for each type of work. As a rule, the scope of application and technological limitations are indicated by the manufacturer on the packaging.
• The length, width and thickness of the tape must satisfy the dimensions of the window and the geometric characteristics of the installation gaps.
• The type of material is selected based on the material of the enclosing structure.
• To seal the internal seams of wooden walls, you should purchase vapor-permeable materials.

Before buying a tape, you need to familiarize yourself with the most well-known manufacturers of this material, who have been supplying their products to the market for a long time and have many positive reviews from satisfied Internet users.

The cost of an error due to poor-quality window installation seam

What happens if, in order to save money, the polyurethane foam is not isolated from contact with the external environment?

• After installation, excess foam is cut off, revealing its porous structure; the material begins to absorb moisture, like a sponge. Wet foam cannot perform its main function - thermal insulation. This means that the window will be ventilated.
• Freezing in winter, moisture in the pores of the foam begins to destroy it. Blowing through the installation seam leads to the appearance of ice on the windows, and the slopes become covered with mold.

• Under the influence of ultraviolet radiation (sun), the foam quickly deteriorates on the outside and ceases to perform its protective functions.

Photo: sun, rain, steam destroy the installation seam
Therefore, according to GOST 30971-2012, when installing windows it is necessary to use special materials to protect the external and internal seam of the window. Insulating tapes and sealants are the most common materials permitted by GOST. Let's consider the advantages and disadvantages of each type of material for sealing the installation seam (window joint).

Vapor barrier

The insulation between the wall and the window consists of three layers:

• Outer. Its function is waterproofing, which means protecting the room from any weather conditions - snow and rain.
• The load-bearing insulation layer is located in the middle of the joint and is responsible for heat and sound insulation. Protection from frost is provided by a porous material resembling polyurethane foam. The waterproofing agent prevents moisture from getting inside.
• The inner layer is also considered thermal insulation. Here the mechanism of heat conservation is different. This layer does not allow heat to escape from the inside, unlike the outer layer, which protects the premises from cold air flows from the street.

Window thermal insulation layers
Window vapor barrier refers to the inner layer, but is not always included in the insulation system. Single-sided self-adhesive vapor barrier tape or double-sided vapor barrier tape is additional protection. The need to use tape increases if the window is installed in a room with a high moisture content: kitchen, sauna, bathhouse.

Installing vapor barrier tapes is no more difficult than installing other types of seam insulation. However, a vapor barrier can help avoid subsequent serious problems with the entire window protection system. When installing a vapor barrier, in some cases you may need a couple of additional accessories, for example, vapor barrier tape. This is worth considering.

PSUL sizes

PSUL tape for plastic windows is available in several dimensional grids and wound into a roll. The length of one bundle can be from 3 to 15 meters. It depends on the thickness of the material. Size is calculated in several states:

• width of the adhesive surface (from 10 to 20 mm);
• thickness in the original (compressed) state (4, 6, 8, 10 mm);
• maximum expansion in a free state (20, 30, 40, 50 mm).

One Velcro tape can fill a seam from 3 mm to 2 cm. For large areas, 2 tapes can be used in parallel. However, to maintain an acceptable level of insulation, the gap thickness should not exceed 4 cm.

In addition to size, the expansion coefficient is of great importance. The higher it is, the less dense the seal is. It is not capable of providing a reliable degree of insulation over the long term. The expansion coefficient when working with PVC should not exceed 30%.

Usage

You can carry out sealing yourself. When working, you will need a syringe, water and mounting tape. To prevent the slopes from getting dirty, you need to stick construction tape on them. Working areas should be thoroughly cleaned and degreased, but products containing acetone should not be used for PVC windows, otherwise unsightly stains will appear on the surface. Slowly squeeze the sealant into the seam with a syringe. The tool must be held at such an angle that its nose straightens the applied putty. Then everything is smoothed out with a finger dipped in water. The seams should be thoroughly filled with the product so that there are no voids left. Even before the material hardens, its excess is carefully removed from the surfaces, without disturbing the integrity of the sealant applied to the seams. The putty should not be applied to all the seams at once, but should be worked in stages.

General information on installing vapor barrier tape

Next, I would like to provide information on installing the 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 without temporarily securing it;
• Carefully mark a line on the frame for mounting the tape;
• carry out calculations, apply markings with the window, stick internal vapor barrier tapes onto 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 vapor barrier tape is carried out before foaming the seam. Before finishing, moistening and filling with foam, the protective paper strips must be removed.

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

The following features must be taken into account:

• external tapes are glued after complete polymerization of the polyurethane foam;
• installation of the 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 placed on the outer coating of the tape; it must provide the required level of adhesion between the surfaces being connected.

If there are gaps between the wall and the frame of the window quarter, another technique is used: the uneven joint must be closed with a special window strip, after which a vapor barrier tape is glued. Vapor barrier tape is glued around the entire perimeter of the window opening in a continuous layer. It is also necessary to take into account that the use of finishing building materials together with vapor barrier tape is recommended only if certain moisture permeability characteristics are met.

Installation features for vapor barrier and waterproofing of window frames

When using adhesive tapes for steam and waterproofing PVC windows, experts recommend following a number of technological nuances and rules to achieve the expected result:

• 
  PSUL must be installed strictly before fixing the window to ensure a tight fit of the material to all contact surfaces.

• Before installing the tape, the surface for the sticker is cleaned of dust, dirt, solid particles and degreased.
• Throughout one seam the tape should be unbroken. The cutting of the material is carried out only after careful measurements of the plane.
• When installing the tape, you need to take into account its subsequent camouflage behind the materials of the slopes, window sills, and ebbs.
• When gluing the tape, it is necessary to take into account an overlap on the orthogonal plane of 50 - 100 mm on each side.
• Before installing the tape over the polyurethane foam, you should wait until the filler has completely polymerized.
• If there is no adhesive on the back surface of the tape, use double-sided tape, which is purchased separately.
• After gluing the tape, you should ensure the quality of the surface fit and prevent the formation of air bubbles.

When installing a window in winter, you should buy in advance a material that can stick in extremely low temperatures without destruction. If these requirements are neglected, the tape may crack or come off when the next thaw arrives.

Types of tapes

The functionality of the tapes is different, therefore, when installing windows, different varieties are used depending on the purposes at each specific stage. A review of the tapes should be carried out.

Features of using window sealants ↑

Window sealants are a dime a dozen on the construction market. They are used to seal frames, glass, etc.:

1. Silicone sealants. The most common material that is made on the basis of silicone rubber. The name “silicone” is apparently given for convenience. Due to their simple production and standardization, they are in great demand. Depending on the substance that ensures vulcanization, silicone sealants are divided into two types: neutral and acetate. Neutrals are well applied to smooth (frames) and porous surfaces (concrete or brick), which makes them suitable for sealing external seams when installing windows. This material practically does not emit toxic substances during vulcanization. It is characterized by high adhesion (bonding) to glass, wood, ceramics, porcelain, PVC, enamel, aluminum and almost all painted surfaces, and also retains its properties at temperatures ranging from -50 °C to +180 °C.

   Acetate sealants should only be applied to smooth surfaces, such as glass. Their strength is higher than that of neutral ones, however, during vulcanization they release acetic acid, which requires good ventilation of the room. Sometimes acetate sealants are called universal.

2. Acrylic sealants. Designed for glass putty. During installation, they are used to protect the mounting foam from moisture, since the vapor permeability of these sealants is quite low. They are resistant to low temperatures and bond well with many building materials, including wet surfaces. However, they are not suitable for resin or bitumen surfaces or gaps where water often enters.
3. Polysulfide or thiokol sealants. Used in a wide temperature range, they are highly elastic, so they are suitable for many materials. They are fluid masses with a density of 1270-1300 kg/m3 and a viscosity of 10 to 60 Pa. To improve the quality of the connection with porous materials, thiokol sealants are used together with primers.
4. Polyurethane sealants. They are the most inexpensive, but are characterized by increased heat resistance, which is excellent for cold coatings: concrete and brickwork. Resistant to acids, oils and weather conditions.

As for liquid plastic, it is a one-component adhesive based on white dissolved PVC. It does not change its color over time, is durable (up to 15 years) and has excellent adhesion to polyvinyl chloride. Resistant to ultraviolet radiation and temperature influences.

Application areas of PSUL tape

A self-expanding seal is most often used when installing plastic windows and doors. Area of ​​use: any area of ​​construction where seam sealing is required.

Possible areas of application:

• sealing roof seams;
• sealing gaps in concrete structures;
• sealing seams in wooden buildings made of timber or logs;
• sandwich panel cladding;
• sealing joints in drains and ventilation pipes.

Regardless of the purpose of use, PSUL tape will last from 20 to 50 years. The temperature range at which installation of a self-expanding seal is allowed is 50 + 90 degrees, so the material can be used all year round.

The sealant can be combined with many building materials. It works well with plastic, natural and artificial stone, wood, and concrete.

Types of mounting tapes for windows

The functions performed by the tapes are different and depend on the location of gluing, the condition of the opening, the features of the future finishing of the slopes, as well as the requirements for the window block. Next, we will consider the most commonly used materials common in the modern construction market.

Pre-compressed sealing tape is used primarily on the outside of translucent structures. Its main purpose is to ensure unimpeded drainage of moisture from the area where the hatch connects to the opening.

Essentially, this is a tape product made of elastic polyurethane foam (looks like foam rubber), usually gray or black. One side of the material is covered with an adhesive composition, insulated with a protective film. The tape is supplied twisted into compact reels or rolls (depending on the size), which need to be unwound only during the installation process, since the material loses its quality over time.

An example of tape expansion over time

The main feature is the ability to fill joints as a result of expansion, which occurs as a result of contact with air. The tape isolates the gap from moisture and external influences from the outside, while simultaneously allowing excess liquid to evaporate from the inside.

Scope of application of PSUL:

• Additional sealing of interfaces between elements of prefabricated structures;
• Sealing the gap between the frame and the opening when installing windows and doors;
• Insulation of joints between small-sized moving units of building facades;
• Filling the external seam between the slope and the frame during the installation of PVC windows.

It is important to understand that to fill the gap efficiently, you need a tape of the appropriate size. For example, if the task is to seal a joint with a maximum width of 40 mm, you will need a PSUL with a nominal size of 45-50 mm.

Water vapor barrier (GPL)

This type of tape product is most popular when installing window blocks. Among its main features it is worth highlighting the following:

• Water vapor barrier mounting tape is designed to seal joints on the room side.
• Polyethylene film is most often used as the basis for self-adhesive material. On one side the tape is equipped with a foil coating, and on the other - with an adhesive composition.
• The adhesive used provides reliable fixation on most surfaces (concrete, brick, cinder block, wood and others). The products of some brands have poor adhesion to foam blocks and aerated concrete, so before purchasing you should consult with the seller or read the attached instructions.
• The structure of the material prevents the penetration of moisture or air both through the tape itself and through the gluing points. This ensures the maximum possible tightness of the joint of the opening and, as a result, the structure as a whole.
• In addition to insulating from moisture, the tape does not deteriorate during prolonged contact with ultraviolet radiation and is not subject to destruction from exposure to aggressive environments (household acids, alkalis and other reagents).

GPL is used for waterproofing installation gaps that arise when installing window and door units, as well as for sealing structures made of metal, wood, concrete and plastic.

GPL-S and insulated GPL

• GPL-S its structure is identical to the GPL described above. The main difference is an additional strip of double-sided tape on the side that is not covered with adhesive. Due to this, the area of ​​fixation of the material on the window block expands. Unlike traditional water vapor barrier tape, GPL-S can be glued to the inner surface of the profile using an additional strip, and the adhesive side to the slope.

• Insulated hydro-vapor barrier tape is an improved modification of conventional GPL. Main features: thickened base layer based on polyurethane foam or cellular polyethylene; a more durable foil component, usually made from high-quality polyethylene. As a result, the tape, in addition to its high waterproofing qualities, significantly prevents heat loss at the joints of the frame and the opening. In addition, the material is quite durable, which ensures the safety of the structure, preventing mechanical damage.

VM (VM+) tape

• VM . Vapor barrier tape designed for sealing joints indoors. It is used in cases where wet finishing of slopes is planned (plaster or tiling). Provides protection from moisture entering the joint of the opening and reliable fixation of the finishing coating.
• VM+ . A modified analogue of the previous product with similar properties. It has the best waterproofing qualities, which allows it to be used in rooms with high humidity (kitchens, showers).

VS (VS+) tape

• Sun. Material with one-sided adhesive coating on a non-woven base. Used indoors for waterproofing window and door openings. Intended only for dry finishing of slopes. For example, plastic, wooden or MDF lining, plasterboard and other sheet materials.
• BC+. Similar to the previous product, also used for dry slope design. Distinctive features: adhesive layer on one side and the presence of an additional strip of double-sided tape on the back; There are modifications with foil coating for additional thermal insulation of the seam.

Diffuse (vapor-permeable waterproofing tape)

It is used outside structures in conjunction with pre-compressed tape or in situations where it is impossible to use the latter.
Traditionally, diffuse tape is used to isolate the area where the molding profile is attached, since PSUL cannot be glued to the place where it is fixed, but there are also frequent cases of use along the entire perimeter of the window block. Butyl rubber, used as the base of the tape, is a fairly elastic material with high adhesion to most surfaces. It is equally firmly fixed on stone, wood or plastic. It is also worth noting that it is environmentally friendly and almost completely harmless to the consumer. The main disadvantage is the flammability of butyl rubber, which requires compliance with appropriate standards for installation and subsequent operation.

Used as an insulating material on the inside of the structure. It is glued to the bottom of the window sill profile as additional protection against blowing from the outside and penetration of steam into the installation seam from the room side.

Classification of vapor barriers for windows

To install a PVC window, vapor barrier tape in a wide variety of varieties and diffusion vapor-permeable tape are used.

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

The tape should be approximately 5 cm larger than the width of the mounting seam.

Based on the material used, there are two types of tapes:

1. Butyl rubber tape with a reinforcing layer of non-woven fabric, designed for sealing joints.
2. Metallized tape, intended for installation in damp rooms.

Accessories for vapor barriers

When installing a vapor barrier, minor difficulties may arise - overlapping strips and overlaps. You may consider this not dangerous for tightness, but in the end you will most likely get problems with heat and vapor barrier. Therefore, when installing a sealed vapor barrier for PVC windows, you may need additional accessories, for example, self-adhesive tape. In some cases, glue is most convenient.

If a vapor barrier metallized tape is attached to a non-smooth surface, it may require additional reinforcing force.

Self-adhesive tape can be the same as the vapor barrier sheets themselves, single- or double-sided. They are purchased if it is necessary to additionally glue the joints of vapor barrier strips and correct damage to the strips.

In the case of a double overlap or adhesive tape to wood or metal, double-sided tape is often used. With double overlap, i.e. When attaching a strip to pipes or doors, it is more convenient to use one-sided.

Cost 1 linear m of vapor barrier tape averages from 25 to 45 rubles. The price tag for additional products, for example, double-sided tape, is quite high (up to 1,400 rubles). Therefore, when purchasing them, everyone is guided by the installation process, the desired degree of confidence in the operation of the system and the possibility of spending money.

Foil self-adhesive hydro-steam heat-insulating tape

Self-adhesive GPL strip allows you to solve problems associated with steam, hydro and thermal insulation of joints, assembly seams, abutments 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, mildew and spores, resulting in an increase in the service life of any structure.

Advantages :

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

General installation recommendations

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

Installation steps:

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

Work must be carried out at a temperature not lower than +10°C.

Self-adhesive steam-, hydro-, and heat-insulating tapes consist of foamed laminated polyethylene, with a layer of metallized polypropylene film applied on one side. On the other hand, a special waterproof adhesive ensures reliable fastening of the material to 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 cellular structure provides an extremely low level of hydroscopicity, which guarantees a high level of moisture resistance.

Polyethylene foam gives the film elasticity, which is very important when sealing uneven seams. Metallized polypropylene tape is intended for finishing the outer layer. The advantages of polypropylene film include a high level of mechanical strength; the material is also resistant to organic solvents, acids and alkalis. This ensures reliable protection of the reflective layer from damage and oxidation.

Polypropylene film also has good vapor barrier properties.

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

Scope of application: steam, hydro and thermal insulation of joints and assembly seams in building structures - door and window blocks, metal, concrete, wooden and plastic products.

Kinds

Today, the construction market is represented by a huge selection of glass sealants. Each of them is characterized by individual characteristics and scope of application.

Depending on the basis on which the material is made, two groups of products are distinguished:

• Acetate.
• Neutral.

Sealants belonging to the first group are most often used for structural sealing of double-glazed windows or for glazing windows. As for the second type, it has high adhesion, so it can be used not only for sealing glass, but also for sealing external seams of facades and load-bearing metal structures.

The sealant may differ in the components included in its composition and can be varied.

• Acrylic. This material is considered ideal for sealing windows. It can be used to cover both new double-glazed windows and to seal old ones. The sealant creates a durable layer between the glass and the frame and prevents air penetration. The result is a tight connection that is resistant to moisture and low temperature. Most builders consider this sealant to be universal for working with glass.
• Butyl. It is a construction product that is intended for finishing double-glazed windows. It is mainly used when several glasses need to be joined together. This sealant is characterized by excellent protection and resists well the penetration of moist steam and air into the space between the glasses. It must be applied to the work surface at temperatures above 100C.

• Polyurethane. The material has excellent sealing structure, so it is often chosen for sealing plastic and glass. In addition, it can additionally serve as thermal insulation. After sealing with such a sealant, the surface gains strength and its service life increases. Craftsmen most often use this material for edge joints. Glass reinforced with sealant is not “afraid” of temperature changes, acids and oils.
• Silicone. It is the most common and popular type of sealants. It is used at almost all stages of construction work. The material is also well suited for sealing facade glass, as it has high performance indicators. The popularity of this product is explained by the fact that it is inexpensive and characterized by excellent quality.

Thanks to its unique characteristics and special composition, silicone glass sealant allows you to reliably seal seams and glue materials together. In addition, the product has found its application in auto repair, as it can act as gaskets. Often you have to deal with the problem of sealing seams between glass and coatings such as metal, ceramics or brick. Many adhesives cannot cope with this, but silicone glass sealant will ideally glue all objects, including elastic polymers, plastic, aquariums, and automobile parts.

In addition, the construction product is used to seal seams between various glass objects. In a car, it can be used to strengthen headlights, fixed windows and hatches. However, when using this sealant, you need to remember that it is not suitable for work that requires combining glass with polymers. When interacting with fluoroplastic, polycarbonate and polyethylene, a chemical reaction occurs and the material loses its properties. In addition, this sealant can deteriorate when exposed to gasoline, synthetic oil and ethylene glycol.

Recently, a new product such as polysulfide sealant can be found on the construction market. It does not contain solvents, is produced not in tubes, but in large jars and is used, as a rule, in the manufacture of double-glazed windows. This sealant is produced by mixing polymers with pigments and a structuring agent, resulting in a sealing material that has high resistance to gas, steam and water penetration. As a rule, such a product is used as a secondary sealant.

The structure of a self-expanding tape and its advantages

High-quality self-expanding sealing tape suitable for use in the temperature range from -55 to +90 °C. According to GOST 30402-96, it is classified as a low-flammability material and has thermal resistance up to +1000 °C. This polyurethane foam-based material is very similar to ordinary foam rubber, since it has a porous structure and is able to shrink and expand. Resistance to external influences and durability of PSUL is ensured by a special composition based on acrylic, with which the tape is impregnated throughout its entire thickness.

This material is vapor permeable, which allows all accumulated moisture to be removed to the street. Due to its structure and composition, PSUL tape for windows and doors has important advantages:

• prevents freezing of the assembly seam;
• repels water and prevents moisture from seeping into the gap between the frame and the wall;
• remains elastic throughout the entire service life;
• traps heat and noise;
• resistant to solvents;
• prevents the development of fungus and mold;
• is a chemically neutral material;
• perfectly withstands exposure to UF radiation;
• provides complete ventilation;
• can be used to seal joints with uneven surfaces;
• compatible with any building materials.

Tape sealant can be confidently considered a universal material, since it is suitable for external and internal use, and can also be used in residential, commercial and industrial premises. In addition to acrylic impregnation, tape manufacturers can use neoprene.

Self-expanding tape is suitable not only for sealing external cracks when installing windows, but also for sealing any other joints between frames and walls.

For interior and exterior work

According to their physical and chemical properties, all sealants are divided into two categories - those used for outdoor work and those used indoors.

Sealants used for external work are subject to certain requirements that facilitate their effective resistance to aggressive external environments.

Seal the external seam with sealant

Requirements for external sealants:

• Chemical resistance. Expressed in successful resistance to mold, water and chemicals.
• Successful resistance to mechanical stress. That is, such a sealant must be durable and not be destroyed by external forces.
• Elasticity.
• Good thermal insulation properties.
• Have a dye in its composition or have an easily colored structure.
• When applied, have a condition in which all hard-to-reach places are easily filled (have fluidity).
• Easy to adhere to surfaces (high adhesion).
• Wide range of application and use temperatures.

Requirements for internal sealants:

• No toxins. This is the main requirement for sealants used in residential premises, preventing poisoning of people, animals and the development of allergic reactions.
• Resistant to biological agents, mold and bacteria.
• Moisture resistance.

Installation of 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 non-woven fabric, provides the required level of moisture insulation of the installation seam and is a reliable barrier to the escape of moisture onto the surface of the internal slopes.

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

In the production of vapor-tight sealing strips, a non-woven fabric coated with a self-adhesive plastic-elastic mass made on the basis of adhesive butyl rubber is used. 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 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 are distinguished by high adhesive properties only if the surface of the internal slope is well cleaned and degreased. Butyl rubber strips have better adhesion and a tighter fit to the wall opening. All these characteristics must be taken into account when choosing one option or another; if necessary, you can always consult a specialist.

Installation steps for 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 carried out with an overlap, at least half of its width;
• remove the protective paper from the duplicated strip and stick it on the outside of the frame;
• The installation of the strip is carried out using a self-adhesive mounting strip in a tensioned state (without bulges 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 match exactly; the protective tape is not removed at this stage.

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

Deterioration of adhesion may be affected by prolonged exposure to cold conditions of acrylic adhesive tape with the release paper removed.

Working with cold window structures can also negatively affect adhesion, since when workers breathe, steam is released from their mouths, which partially condenses on the surface of the block, resulting in reduced adhesion of the adhesive surface.

In order to prevent this phenomenon, the interval between removing the anti-adhesive paper and directly gluing the tape should be minimal. Before gluing the tape, you must also wipe the surface of the window block with a paper napkin or dry rag.

Waterproofing windows from outside

The installation seam is most susceptible to the harmful influences of the external environment from the street side. Therefore, even if you do not use special insulating agents, you need to at least plaster or cover the external slopes with panels. Installing windows according to GOST involves the use of either tape materials or water-based sealant.

Waterproofing tape

For exterior work, two types of sealing materials are most often used - PSUL and waterproofing diffuse tape.

• PSUL. Pre-compressed sealing tape is visually very similar to foam rubber, in most cases it is dark gray in color. An adhesive mixture is applied to one of the edges of the tape, covered with paper film. The sealant is produced twisted into reels (wide products in rolls), which are unwound immediately before installation on the block, otherwise the sealant will become unsuitable for use. One of the features of PSUL is its expansion in cross section, which makes it possible to fill all the irregularities between the block and the opening. The tape does not allow water to pass into the seam and allows it to evaporate from it.
• Diffuse vapor-permeable tape. Most often it is used in combination with PSUL to insulate the lower part of the window block at the installation site of the drip profile.

  
  If the design of the opening does not allow the use of pre-compressed materials, a diffuse vapor-permeable tape can be installed along the entire outer perimeter of the glazing. Its characteristics are similar to PSUL - it also well insulates the seam from external moisture and promotes the removal of internal moisture. The main differences are in the installation method and maintaining the shape after pasting, which does not allow filling in uneven areas in the opening.

Both types of waterproofing are compatible with almost all finishing materials and can be used to seal any seams.

Acrylic sealants for sealing the installation seam of windows according to GOST

Let's consider the advantages of sealants for insulating a heat-insulating layer.

Advantages of sealants relative to mounting tapes:

• A more hermetically sealed application means you don’t have to level the opening in advance and don’t have to wait for it to dry. Due to their liquid consistency, sealants fill cracks, irregularities and voids in the opening during the application of the external seam.
• Higher water resistance - in order for water to begin to penetrate through the sealant layer, a pressure drop of more than 600 Pa is required (this happens, for example, with a wind of more than 30 m/s). Through the joint of the tape with a wall or window, water begins to leak at 150 Pa, i.e. already with a wind of 17 m/s.
• Higher seam protection against blowing. A 2mm layer of sealant can withstand hurricane winds at a speed of 45m/s for at least 3 hours without blowing. No ribbon can withstand such wind.

Photo: the tape does not have a tight connection with the opening and the product; additional sealing is required

• Sealant can be used to cover an installation gap of any width, and the range of external sealing tapes is limited to several sizes (10, 12, 15, 20mm, less often 50mm)
• High maintainability – a damaged area of ​​sealant can be easily restored; you don’t even have to remove the old one. The damaged tape will have to be replaced completely, which may entail a complete reinstallation of the window and slopes.
• More affordable price relative to high-quality tapes.

Disadvantages of sealants compared to tapes:

• In winter, installation will take two days: to apply the sealant, you need to wait until the foam hardens. In winter, this happens for several hours, so processing the seam will have to be postponed until the next day.
• Applying sealant takes longer than applying tape - approximately 15-20 minutes, including protecting the window with masking tape.
• It cannot be used when repairing an assembly seam when the window is already installed and requires repair.

According to industry experts in the field of installation, sealants today occupy about 60% of the market, due to the optimal price-quality ratio.

How to use?

Sealing can be done independently. Contacting workers is an unnecessary and unreasonable waste. With instructions, you can complete this job in no time. We will assume that the slopes have already been made earlier, so we will not dwell on this issue.

The algorithm for sealing work will be as follows:

• The first point will be preparing the tools and consumables. During the process, you will need a syringe for applying sealant, a container of water and construction tape.
• The slopes need to be prepared for further work. The essence of the preparation is to stick construction tape, which will protect the window structure from contamination and save us time.
• The working area must be thoroughly cleaned. There should be no dirt or even dust left. It is also necessary to remove the protective film to the smallest fragment. To degrease plastic structures, it is prohibited to use solvents containing acetone. With this treatment, cloudy, matte stains, spots that differ in color and other troubles may appear on the surface.

• Using a construction syringe, slowly squeeze the sealant into the seam area. The tool should be positioned at such an angle that its nose smoothes the material being applied.
• The remaining unevenness and other defects are smoothed out with a finger previously moistened in water. This trick will prevent the material from sticking and provide a smooth surface. The seams must be filled well with putty so that there are no voids.
• Remaining material must be removed from surfaces before it hardens. In this case, it is convenient to use a damp sponge. You must act very carefully so as not to damage the integrity of the sealant applied to the seams.
• There is no need to apply putty to all the seams at once. It's better to work in stages. In this case, it will be possible to avoid hardening of the material before it is leveled and residues are removed.

Proper use on PVC windows

Question: How to properly use vapor barrier tape for PVC window structures, what should the temperature be? Answer: Installation of vapor barrier tapes on plastic window structures is carried out as usual in rooms with high humidity levels (swimming pool, bathhouse, kitchen).

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

Summer tapes are designed for use at temperatures of 5-35 degrees, while winter tapes have proven themselves to be excellent in conditions below zero. The width plays an important role when choosing a tape; it should be 45 mm greater than the width of the assembly seam. Compliance with this condition will help achieve the required level of 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 fastening it, mark the installation lines of the vapor barrier tape on the frame and 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 gluing to the wall.

Installation of vapor barrier tape on a plastic window is carried out in one piece; breaks are unacceptable.

The next stage involves assembling the window structure with sashes and major installation into the opening. At the final stage, the vapor barrier strip is glued to the window sill.

An example of installing PVC windows with vapor barrier films in the video:

Tapes for window installation according to GOST

High-quality glazing requires serious consideration and is impossible without proper insulation of the gap between the opening and the window. Often, organizations that install translucent structures limit themselves to traditional polyurethane foam, which is subsequently covered with plaster or other finishing materials. This approach has proven itself relatively well and in some cases does not cause any complaints from the consumer throughout the entire service life of the window.

However, glazing with one level of sealing of the opening does not meet the state requirements for the quality of services or goods provided, that is, GOST. To comply with these requirements, additional insulation is required at the junction of the window and the opening both from the street side and from the room side. Such insulation is ensured using special mounting tapes.

Scheme for using mounting tapes on windows Top view

Mounting tape for windows is a self-adhesive material on a polymer or fabric basis, designed for additional sealing of window or door openings.

How to choose the right PSUL tape for plastic windows

In order for the tape to reliably seal the seam, you will have to choose the right size. Otherwise, noise, moisture and heat insulation will be compromised. Water will begin to accumulate in loosely fitting material, causing premature wear. In some cases, the PSUL may be squeezed out by mounting foam or pulled out in strong winds.

Rules for choosing a sealing self-expanding tape:

1. To seal window seams, do not use tape smaller than 20 mm. Its thickness is not enough to tightly close the joint. The result will be moisture accumulation, leaks and premature aging of the tape.
2. It is better to take the thickness of the compressed seal about 8 mm. It is enough to eliminate a standard window gap of 8-13 mm. For larger seams, use a tape with a thickness of 10. Small cracks of 4-6 mm are insulated with a 4 mm PSUL.
3. The width of the adhesive layer should be selected based on the dimensions of the window or other surface to be sealed. Insufficient area of ​​the adhesive area will make the structure fragile to external factors.
4. Buy material from trusted manufacturers. It is better to give preference to European brands. Although domestic tapes are cheaper, the risk of running into a fake is higher. Therefore, before purchasing, you should ask the seller for a quality certificate for the seal.

Regardless of brand or size, the tape takes time to expand. It depends on the ambient temperature. For example, in 30-degree heat it will take on the required dimensions in half an hour, and at zero it will take up to 2 days.

Please note that only a new roll of tape can be used to seal gaps. After opening, the PSUL expands and becomes unsuitable for use.

GPL tapes

GPL are vapor-waterproofing tapes that perform moisture protection as the main task. These tapes form the outer layer of insulation with an additional vapor barrier function . Self-adhesive vapor barrier tape is made of polyethylene foam.

Polyethylene foam has a porous structure, has good thermal insulation properties and almost zero hygroscopicity (does not absorb moisture). The presence of this material in the tape makes it elastic and provides high-quality sealing with any surface, including uneven ones.

Insulating tapes for sealing the installation seam of windows according to GOST

Three types of tapes are used for installation:

• PSUL tapes – waterproofing external tape made of polyurethane foam, glued to the outside of the opening;
• Vapor barrier foil tape with an adhesive layer for the inside of the seam;
• Membrane diffuser tapes for the inside of the construction seam.

Advantages of installation using tapes:

• The speed of installation of tapes on the opening is twice as high as compared to applying sealant. Tapes can be glued until the foam is completely polymerized, without waiting for it to harden. Installation can be done in one day.
• The window and opening do not get dirty;

Disadvantages of installation using tapes:

• Risk of damage to the tapes during or after installation, which entails the need for their complete replacement;
• Careful preparation of the opening is required (about 5 days) if it is not leveled: filling potholes and voids, organizing a quarter in a quarterless opening and allowing the putty to dry. All this increases the cost and time of installation;
• It is necessary to keep tapes of different widths in stock and use them depending on the width of the seam, which also increases the cost and can lead to installation failure when there is no tape of the required width.
• At negative temperatures, the expansion time of the PSUL increases greatly, the foam can come out - the seam will have to be redone.

How to use it correctly?

The technology for using installation years when installing PVC profile windows is quite simple. I use the following algorithm:

Preparing the opening

1. First, I prepare the opening: I remove the old structure, level the walls, remove dust and dry all surfaces. It is desirable that the edges of the opening be more or less even, therefore, before installing the window, it may be necessary to refine them using a quickly hardening solution.
2. Then I cut water vapor barrier tapes, PSUL and diffuse material. I cut the products along the length of each side of the window with an overlap of at least 10 cm (these areas are used to form a corner joint).

Gluing tapes to the frame

1. I paste the tapes onto the window frame, removing the protective film from one of the adhesive strips. I glue PSUL in a compressed state onto the front surface of the structure from the outside.

It is desirable that the PSUL be completely hidden behind the wall fence, so before gluing, I usually fit the window to the opening, making marks at the installation site.

1. I install the structure in the opening and fix it using the chosen method - either using anchors or using mounting plates.

Sealing corners

1. I fill all the gaps with self-expanding polyurethane foam.
2. I remove the protective strips from the inner and outer tape and glue their edges to the opening, completely covering the foam.
3. If installation is carried out in winter, I use specialized materials with glue that retains adhesive ability at subzero temperatures.

Installation of ebb and flow over diffuse material

1. Before installing additional elements, I separately glue to the stand profile or the bottom of the frame a material that protects the space under the window sill and under the drainage strip.
2. At low tide, I stick a PSUL strip onto a horizontal surface: it acts as a shock absorber, and therefore the metal canopy will not rattle when there are gusts of wind or raindrops hit it.

Materials for installing window structures

PSUL tape

PSUL tape is designed for installing window blocks and ensures the creation of a ventilated assembly seam.

The tape is manufactured in accordance with GOST 30971-2002 “Installation seams of joints connecting window blocks to wall openings.”

The material guarantees the durability and reliability of the installation seam. PSUL tape is a self-adhesive polyurethane foam tape impregnated with a special composition, which is supplied in rollers in a curled state.

An extensive selection of sealant sizes allows you to choose an option for sealing seams of any size.

PSUL tapes have a wide range of applications and are distinguished by their versatility and multifunctionality.

The vapor barrier strip is used to protect fixed and moving joints from low temperatures, noise, moisture, dust and other adverse factors.

Standard areas of use:

• sealing joints, as well as moving seams of blocks, panels and small structures on building facades;
• sealing the gaps between the wall opening and the door/window frame;
• sealing seams of adjacent sections of prefabricated structures;
• sealing the space where translucent structures adjoin the walls.

Materials for waterproofing plastic windows

After determining the cause of condensation, it is necessary to prepare consumables. The list depends on the task to be accomplished:

• initial window installation;
• repair of joints;
• frame repair.

In the first case, you need polyurethane foam and waterproofing tape. In the second, only tape is enough. In the third, you need to use silicone sealants. Let's look at these materials in more detail.

Waterproofing tape for window

There are 4 main types of waterproofing tapes:

• moisture- and steam-resistant on a self-adhesive basis;
• insulated;
• pre-compressed;
• for external use.

The first 3 types of tapes are used only for interior work. The peculiarity of ordinary waterproofing tape is that it does not allow not only water to pass through, but also air. If the house is built of foam or aerated concrete, use is not recommended. If the joint has voids, a fungus will inevitably form in it, which will begin to destroy the stone. The price starts from 60 rubles per roll of 5 m.

The insulated tape differs from the first option only in that it is covered with a special reflective material, which prevents the penetration of cold from the street and the leakage of heat from the room. Relevant for use in cold regions. The price varies from 80 to 400 rubles. per roll 5 m.

Pre-compressed tape is mainly suitable for foam concrete structures as it allows air to pass through but prevents moisture penetration. In cold regions, it makes sense to use only in conjunction with an external diffuse tape. Price 60-300 rub. per roll 5 m.

Tapes for outdoor use are distinguished by the fact that they are resistant to natural phenomena: rain, snow, sun. However, they only protect against moisture from the street and prevent ventilation of the seams. They are optimally suited if renovations have already been made inside the premises. Price 80-500 rub.

To correctly identify the tape, it is enough to study the GOST standards:

• GOST R 53338-2009 “Vapour-permeable, self-expanding, self-adhesive tapes for construction purposes”;
• GOST 30971-2012 “Mounting seams of junctions of window blocks to wall openings. General technical conditions";
• GOST R 52749-2007 “Window installation joints with vapor-permeable self-expanding tapes.”

Polyurethane foam

Polyurethane foam is used exclusively at the window installation stage. According to the principle of operation, liquid foam is blown into the cracks between the frame and the wall and begins to dry and expand, filling all the voids. Repeatedly blowing the seams with foam will no longer give the expected result. First you need to remove all the old foam and re-blow it. Only in this case will the waterproofing be done efficiently.

Another undeniable advantage of foam is that it does not harbor insects, bacteria, fungi and other parasites. On the other hand, there is a significant drawback - the foam fades very quickly in the sun and begins to crumble, so the seams must be sealed with waterproofing film.

The choice of manufacturer is not particularly important; pricing ranges from 40 to 200 rubles per jar.

Window sealant

This is a collective name for a whole group of finishing materials. Window sealants are sold in different forms:

• paste;
• tube;
• ready mixture in a bucket;
• dry mixture.

The first two options are suitable for sealing small seams, since they are sold in small volumes and cost up to 200 rubles. Ready-made mixtures are used if the work of installing the sealant will be completed in one go. After opening the can, the sealant dries out and becomes unusable. There are different displacements on sale from 1 to 20 liters. Cost from 150 rub. per liter

The dry mixture is cheaper, on average 300-400 rubles. per kilogram. When diluted, 3-5 liters of sealant is obtained. In terms of physical and operational properties, it does not differ from the finished mixture.

Liquid sealant for windows

Liquid assembly sealant is also a complex group of insulation, which is used both for filling installation seams and for repairing the frame itself, if the rubber on the glass unit has worn out or received mechanical damage.

In general terms, we can highlight the high reliability of these insulations, ease of use and durability. However, their cost is the highest, from 300 rubles. per jar. Clear and white sealants are available for sale.

Window tape

The assortment includes a large selection of high-quality window tapes, a variety of sizes and in the required quantities. Internal and external window tape is widely used in a variety of areas of construction and installation.

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

The tape is intended for waterproofing the installation seam of a translucent structure under low tide, as well as any other construction seams and joints. The tape has two adhesive strips on one (optional) or two sides. One strip is intended for attaching the tape to the translucent structure, the other is for attaching the tape to the wall slope. The use of Robiband waterproofing tapes provides reliable protection of the mounting foam from moisture from the street side and ensures the removal of moisture from the foam to the outside.

How to install the tape?

This material does not require any special tools or skills for installation. It is enough just to clean the window joints, making them smooth. It is important to remove dust and dirt from structural elements. To ensure that the tape adheres well, you can treat the joints using a special dust cleaner, having previously primed them. After this, the tape is glued like regular tape. It is advisable to do this evenly.

The tape is applied first on one side of the structure, directly on the seam. Make sure that the tape does not bend and should not be pulled. When working with an angle, the strip is cut to the required size and fastened joint to joint. You will have to wait about 4 hours until the material swells completely if the process occurs at a temperature of about 20 degrees.

The tape for windows should be selected in such a way that the degree of swelling will allow the joint to be completely filled. If this indicator is insufficient, then voids will remain in the structure, which will make the room less airtight.
