Self-adhesive vapor barrier tape. Using tape to insulate windows. Installation is carried out in the following sequence

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

The first variety is suitable for the summer period and can be used at temperatures ranging 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 for joints of different sizes. When choosing a vapor barrier tape, you should take into account that its width should be 45 mm more than the installation seam.

general description

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

Characteristics of foil vapor barrier tape

Foil hydro-steam and heat-insulating tape is glued to cleaned, dry, as well as previously degreased surfaces. The material itself is supplied in boxes, the dimensions of which are 420x420x600 mm. It must not be operated at temperatures below +10°C. The tapes are based on foamed polyethylene, which is laminated and metallized with a polypropylene film on one side, while on the other side there is a waterproof adhesive layer that reliably secures 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 the sealing of joints with varying degrees of unevenness. High mechanical strength was achieved due to the presence of a polypropylene film, which is resistant to alkalis, organic solvents and acids. The reflective layer is protected from mechanical damage and oxidation. The adhesive layer consists of a water-resistant adhesive, which is created on the basis of synthetic rubber. It has improved adhesion to various materials, which allows the use of the tape without prior surface preparation.

For reference

You can not be afraid that the vapor barrier tape will stick together in a roll, as there is a protective siliconized layer on its surface. Such a steam-hydrothermal insulation is used for seams, knots and joints of various building structures, including when installing window blocks, wood products, metal, plastic and concrete.

Material dimensions

The thickness of the film is 20 µm, while the length is 15 m, and the width can vary from 90 to 200 mm. 120 and 150 mm act as intermediate values.

Specifications

Vapor barrier tape for windows has a high coefficient of thermal reflection, which reaches 95%. The coefficient of thermal conductivity 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). The thermal resistance is 0.031 °C/W, which is true for one millimeter of thickness. Professionals are sometimes also interested in such a characteristic as specific heat capacity. In the case of the described one, this parameter is 1.95 kJ / kg ° С.

Under 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 combustibility group G2, smoke-generating ability - D3. The density of the material can be equal to 50 and 80 kg/m 3 .

Features of installing the sealing tape

The vapor barrier tape for windows, the technical characteristics of which were presented above, must be installed according to the algorithm developed for this material. For internal sealing of the seam, a duplicated vapor barrier tape based on aluminum foil is used. For reliable and easy fixing, it has adhesive strips, which are located on both sides. The tape must be installed around the entire perimeter of the window, and then closed with slopes that are installed in a dry way.

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 must be added 10 cm each, which will go to the corner joints. Along the length, the tape is overlapped, the width of which should be approximately 1/2 of the width of the material.

Work methodology

The vapor barrier tape for PVC windows, the use of which is described in detail in the article, is released from the protective paper on the side of the duplicated strip at the next stage. The material can now be glued to the frame profile. This must be done in a taut state, 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.

In order for the adhesion of the adhesive strips not to be reduced, it is necessary to keep the structure open for a shorter amount of time, and before gluing the window surface must be wiped with a soft rag or paper towel.

Conclusion

The vapor barrier tape for windows, the density of which was mentioned above, should be installed in one piece, there should be no gaps on even surfaces. At the final stage, you need to install the tape on the windowsill, and then assemble the window with the sashes.

Salute, readers!

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

What battles sometimes flare up there!

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

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

If you do not yet know what a vapor barrier tape is, then this topic is just for you.

Welcome!

Vapor barrier tapes for windows, as well as good finishing of slopes and installation seams, will provide decent window performance. In order for the window in your house to function well and for a long time, you should not miss such a moment as installing a vapor barrier tape.

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

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

Varieties of vapor barrier tape

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

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

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

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

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

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

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

To protect the installation seam from high humidity for dry finishing of slopes, there are metallized vapor barrier tapes on the market.

General information on installing vapor barrier tape

Initially, you need to prepare your opening: clean the inner and outer surfaces of the opening and frame from dirt, dust and other debris. The frame is inserted into the opening and is not temporarily fixed.
After gently mark the line on the frame for attaching the vapor barrier tape.
After carrying out the calculations and marking with the window, we remove the frame and glue our internal vapor barrier tapes. We do not remove the paper strip that protects the inner adhesive layer, which later attaches to the walls.

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

Helpful advice!

Therefore, before finishing, moistening and filling with foam, you can remove the protective paper strips from the vapor barrier tapes.

This will allow you not to lose the adhesive properties of the tape. If you are conducting hidden installation, then the tape should be attached to the ends of the structure from above and on the sides, and from below to the installation profile.

External heat-insulating tapes can be glued no earlier than the complete polymerization of the mounting foam.
Installation of vapor barrier tape under the window sill can be done last. When installing a vapor barrier tape under a plaster layer, the tape must have an outer coating, which will provide the necessary adhesion to this plaster layer.

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

Installing a vapor barrier tape on windows is installed in a continuous layer along the entire contour of the opening.

Do not forget that the use of finishing building materials in combination with a vapor barrier tape is allowed only if the moisture-permeable characteristics are observed.

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

a) vapor barrier tape (duplicated) based on aluminum foil laminated with non-woven fabric, allows you to protect the mounting seam from the inside from moisture and prevents it from escaping from the seam to the surface of internal slopes.

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

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

A feature of butyl rubber tapes is their rather large weight. And, if we compare butyl rubber and reinforced foil tapes with the same width of 120 mm, it turns out that reinforced foil tape is almost 5 times lighter than butyl rubber tape.

The low weight of the tapes makes them easier to work with during installation, and also significantly reduces transportation costs when transporting tapes over long distances.

However, tapes based on reinforced foil with adhesive strips have adhesion only to a well-cleaned and degreased surface of the inner slope, while butyl rubber tapes have a tighter abutment and better adhesion to the wall opening.

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

Cut the tape into pieces with a length equal to the width and length of the window +10 cm (to form corner joints). Docking of tapes along the length is allowed "overlapping", not less than ½ of the tape width.
Remove the protective paper from the vapor barrier tape from the side of the duplicated strip and glue it to the frame profile from the outside.
The tape is fastened by means of a self-adhesive duplicated mounting strip in a taut state (tightly, without folds or swelling) to the outer surface of the box from the inside vertically and horizontally to the ceiling. The inner edge of the adhesive layer must match the inner edge of the frame. The tape protecting the butyl rubber layer is not removed at this stage of installation.

The adhesive strip has a sufficiently high resistance to low temperatures without loss of adhesive properties.

Lack of adhesion can occur if the acrylic adhesive strip is kept in the cold for a long time with the release paper removed.

Also, the adhesion of the adhesive strip decreases when working with cold window blocks, since when the worker breathes, steam (moisture) is released, which partially condenses on the surface of the cold window block, which also reduces the adhesion of adhesive strips.

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

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

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

The tape allows you to protect the installation seam from moisture and steam emanating from the room and thus do not allow condensate to escape to the window slopes. Vapor barrier tapes are produced with one and two adhesive strips.

Tape with two adhesive strips is very convenient to attach to the window and to the slope. Vapor barrier tapes are divided into summer and winter, depending on the weather conditions in the room.

Summer tapes can be used at air temperatures from +5 to +35C, and winter ones at air temperatures below 0 degrees. The window tape should be chosen so wide that it is 45 millimeters wider than the width of the mounting joint. This will allow you to provide a reliable vapor barrier for the installation seams of your windows.

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

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

Helpful advice!

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

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

Hide

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, cold air will not enter the room through the joints, 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 the window frame and the wall, through which cold air will enter the room. There will be drafts, the windows will sweat a lot and freeze at the joints.

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

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

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

Why is vapor barrier used in plastic structures?

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

Workers must ensure that they comply with the following conditions:

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

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

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

What should you know about sealing?

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

Window tape is great for protecting foam. Even if you are going to use architraves, which will protect the structure from the weather, and also be able to give the frame a decorative look, it is worth gluing the tape before installing them. 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.

Specialization: a professional in the field of construction and repair (a full cycle of finishing work, both internal and external, from sewerage to electrics and finishing work), installation of window structures. Hobbies: see column "SPECIALIZATION AND SKILLS"

Waterproofing tape for PVC windows, as well as other materials for installation, are used relatively rarely: their use increases the cost of work, since a set of high-quality mounting tapes for installing one design costs about 15 - 25% of the cost of the entire window.

And yet, if you plan to glaze the house "for yourself", using modern materials is not only possible, but also necessary. That is why I decided to write a short review on mounting tapes, their purpose and proper use.

Purpose of mounting tapes

If approached from a formal point of view, then the use of special vapor-permeable and vapor barrier materials for the installation of PVC structures is necessary, first of all, according to the requirements of industry standards. The use of tapes is regulated by the following documents:

GOST R 53338-2009 "Vapour-permeable self-expanding self-adhesive construction tapes";
GOST 30971-2012 “Mounting seams of adjoining window blocks to wall openings. General technical conditions”;
GOST R 52749-2007 "Mounting window seams with vapor-permeable self-expanding tapes".

That is, the installation of windows in accordance with GOST without the use of tapes is impossible in principle. But there are also rational explanations for the need to use such materials. Some of them are set out in the already mentioned GOSTs, and some can be formulated based on many years of experience in the installation, repair and operation of translucent structures:

To seal the joint between the window and the window opening, a self-expanding mounting foam based on liquid polyurethane is used. Despite the presence of a number of objective advantages, the foam also has disadvantages - first of all, it is vulnerability to ultraviolet radiation.
To protect the foam from UV radiation, a self-adhesive tape is used that covers the assembly seam from the outside.

The next aspect that justifies the need to use special tapes for mounting is ventilation, or rather, the removal of liquid. When operating a window without additional protection, which is formed in the room, it partially collects inside the installation seam, reducing the efficiency of heat saving. To avoid this, a vapor barrier material can be used to seal it from the inside of the room.
However, it is important not only to protect the foam from moisture ingress, but also to ensure the unhindered exit of water vapor outside the assembly seam. To do this, only a vapor-permeable tape is used for exterior decoration, which guarantees normal diffusion of moist air. .

The question of whether it is necessary to glue a vapor barrier tape or use a vapor-permeable material is largely debatable. On the one hand, the effectiveness of these materials is indeed quite high, so using them in the installation will clearly affect the functionality of the window in the best possible way.

On the other hand, the price of mounting tapes is also rather big, therefore, to save money, you can choose other methods: from the inside, for example, install a slope made of plastic (in principle, it provides good hydro and vapor barrier), and from the outside - finish the mounting seam with vapor-permeable plaster, followed by painting .

And yet I repeat: the use of special tapes when installing a window structure in an opening is fully justified both in terms of standards and in terms of optimizing the indoor climate.

Varieties of materials

Type 1. Hydro vapor barrier tape

For the installation of PVC windows, a variety of tapes are used. Each type of such material has its own characteristics and advantages, therefore, in order to achieve the maximum effect, materials should be combined, combining their functional advantages in the best possible way.

I’ll start my review of the materials used when installing windows, with the most popular - with a vapor barrier tape:

Self-adhesive hydro-vapor barrier mounting tape (HPL) is a tape material that covers the mounting gap from the side of the room.
The basis of the tape is polyethylene or foam polyethylene film. On one side, the plank is laminated with a thin layer of aluminum foil, and on the other side, one or two strips of adhesive are applied for installation.
The adhesive mixture used for application provides good adhesion to most materials - wood, concrete, brick, etc. Problems can arise when trying to paste over an opening made of gas or foam concrete, therefore, before buying mounting material, I recommend consulting with the seller or carefully studying what the manufacturer's instructions say about this .
The structure of the tape provides almost complete tightness of the finished assembly seam: neither the place of gluing nor the polyethylene strip itself allows air and water vapor to pass through.

The polymer structure provides the product with additional advantages: the finishing material is not afraid of not only moisture, but also the effects of acids, alkalis, and other chemically active substances, and also does not degrade under the influence of ultraviolet radiation.

Type 2. Insulated waterproofing tape

The insulated tape is, in fact, a modification of the usual waterproofing material. Its key features include:

increased thickness of the base, which is made exclusively from polyethylene foam;
a denser foil layer based on a durable polypropylene film.

Thanks to these design features:

The product is no worse than preventing the diffusion of liquid and water vapor and the penetration of moisture into the middle part of the assembly seam. This ensures the most effective hydro and vapor barrier.
The increased thickness of the base and its porous structure help to reduce heat loss. Foamed polyethylene acts as a window insulation.
Finally, the foil coating also plays an important role. A thin layer of metal on an elastic base reflects infrared radiation, acting as a "thermal mirror". At the same time, most of the heat generated by heating devices is returned to the room.

The disadvantages of such products, I would include their rather large dimensions: finishing the mounting gap with insulated tapes requires subsequent masking of the junction using slopes, which is not always included in our plans.

Type 3. Pre-Compressed Tape (PSUL)

Another versatile material is PSUL (pre-compressed sealing tape). This material is used to ensure self-ventilation of the assembly seam:

The tape is a strip of porous polyurethane foam impregnated with a special compound. On the one hand, the strip is equipped with an adhesive layer protected by a special protective coating.
The product is supplied in a rolled form (rolls or bobbins). It is necessary to unwind the material immediately before installation, since over time the product loses its properties.
During installation, the protective coating is removed and PSUL is glued onto the window structure. After that, the impregnation reacts with air, due to which the linear dimensions of the product increase. The tape expands and completely covers the mounting gap.

Full and high-quality overlap is possible only if the nominal size of the product specified by the manufacturer corresponds to the dimensions of the gap. So, for example, if I need to close a 35 mm gap with my own hands, then for work I take a PSUL with a width of about 40 mm.

After expansion, the material becomes completely vapor-permeable. Due to this, an unhindered exit of water from the assembly seam is ensured.

Type 4. Internal tapes

In addition to these varieties, other products are also used for interior decoration of slopes. Their main features are conveniently analyzed according to the table, which I will give below:

Marking	Description
sun	A product that you use for the installation of window structures, if you plan to finish the slopes in a dry way (drywall, plastic, lining, etc.). Provides effective vapor barrier, prevents moisture from entering the thickness of the assembly seam. The tape is mounted using a self-adhesive layer with a protective coating.
BC+	It is used for the same purposes as the BC tape, but at the same time it has a greater thickness. An additional advantage is the presence of a foil layer, which provides more effective vapor and heat insulation.
VM	Hydro and vapor barrier material, which is used if it is planned to plaster the slopes on the inside of the window opening. We protect the mounting foam from moisture ingress, while ensuring maximum adhesion to the plaster mass.
VM+	A more efficient version of the previous product, used for the same purposes. The key feature is increased moisture resistance.

Other types of mounting tapes

In addition to the products described above, other types of tapes are used for the installation of translucent structures:

Diffusion tape for outdoor decoration. It is used in combination with PSUL or with polyurethane foam. Provides protection of the assembly seam from moisture and ultraviolet radiation while maintaining vapor permeability. Finishing the junction with diffuse material allows you to maintain the natural level of ventilation: air will freely escape from the middle part of the mounting gap.

Butyl rubber mounting tape under the window sill. As the name suggests, it is used to seal the junction under the window sill and protect the insulation from blowing, moisture and heat loss. Like other materials from this category, installation is carried out using a self-adhesive layer.
Non-woven material for installation under the tide. It has high rates of vapor permeability, it is glued to the foundation of the opening under the drainage strip. In addition to providing ventilation, it significantly reduces the noise of galvanized metal ebbs, acting as a shock absorber and extinguishing some of the loud sounds.
Adhesive tape is a versatile material that is used for mounting lightweight structures. For example, self-adhesive reflective film is popular, and a mosquito net with a fastening tape is also very convenient to use.

How to use correctly?

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

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 rapidly hardening mortar.
Then I perform cutting of hydro-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 sections are used to form the corner joint).

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

It is desirable that the PSUL is completely hidden behind the wall railing, therefore, before gluing, I usually try on the window to the opening, making marks at the installation site.

I install the structure in the opening and fix it in the chosen way - either with the help of anchors or with the help of mounting plates.

All gaps are filled with mounting foam made of self-expanding polyurethane.
I remove the protective strips from the inner and outer tape and glue their edges to the opening, completely covering the foam.
If the installation is carried out in winter, I use specialized materials with glue that retains adhesiveness at low temperatures.

Before installing additional elements, I separately glue a material to the support profile or the lower part of the frame that protects the space under the window sill and under the drainage strip.
Under the ebb itself, I glue a PSUL strip on a horizontal surface: it acts as a shock absorber, and therefore the metal visor will not rattle when the wind gusts and drops of rain fall on it.

Cost of materials

As I noted at the very beginning, the high price of mounting tapes partially limits their distribution. But at the same time, if you know exactly what you need, there is a chance to meet the budget allotted for glazing.

Conclusion

Both vapor permeable and vapor barrier tape for plastic windows may not be included in the required set of parts for successful installation. But their use allows you to fully comply with the requirements of GOST. And also to ensure the formation of a favorable microclimate in the room - primarily due to the normalization of the assembly seam.

The video in this article will help you master the technology of using such details, and when choosing a product, you can consult with me and other experts by asking questions in the comments.

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

When installing a window in an opening, remember that its service life is related to how competent the installation will be. Even the highest quality structures will not be used for a long time if the installation is not done correctly. Due to improper work, moisture will gradually penetrate the walls, leading to the destruction of building materials and the spread of mold.

Vapor barrier tape

When installing the frame, consider a few important points:

On the inside of the room, we make a denser layer of mounting solution (for example, foam).
For high-quality sealing of all gaps, we use three-layer protection - the outer material saves from the effects of precipitation, the middle layer is responsible for thermal insulation, and the coating of the inner surface is for vapor barrier.

Vapor barrier provides reliable protection of the heat-insulating layer from condensate, which is present not only in the bathroom, but also in an ordinary room. In the process of finishing window slopes, we glue a special tape. The principle of vapor barrier is based on blocking the contact of moisture with the mounting foam, which forms the middle protective layer. Materials with low elasticity and water and air permeability are suitable for these purposes. When installing windows on a vapor barrier, you can not save. Such neglect will lead to rapid wear of frames, plaster and finishing materials.

To protect the seam, special vapor barrier tapes are usually used. They come in the form of a coiled and compressed sponge-like material. Absorbing moisture, the material swells, sealing all existing gaps. The vapor barrier tape for plastic windows has a number of advantages:

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

2 Classification - what characteristics to look for

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

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

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

Moisture Insulation Tape

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

Metallized vapor barrier material is used for gluing seams with joints in rooms with high 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 of different widths. When selecting material, add 45 mm to the width of the seam.

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

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

First on the list is PSUL (pre-compressed self-expanding sealing tape). It provides a high-quality fit of the window frame or door frame to the wall. This tape is used for vapor barrier of external joints and seams.

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

Robiband VM tape for vapor barrier

Robiband VM tape for vapor barrier is the next high-quality version of the material for processing seams. It is used for interior work, and a wet plaster solution is applied on top. Vapor barrier VM + is a sophisticated option with better performance.

The last type is GPL (hydro vapor barrier material). It is produced from high quality polyethylene foam. The tape has one laminated side, as well as an additional metallized layer. Its second surface is completely covered with glue. This tape is universal, that is, it can be used for all types of work. Its variety is GPL-S tape, which has similar characteristics.

4 How to stick insulation - we work without errors

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

The gluing process consists of several steps:

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

In order for the window structure to serve for a long time, its installation must be carried out with strict observance of the existing technology. The outer material for steam, heat and water insulation must be glued after the mounting foam is completely polymerized. We process the seam under the window sill last.

If the tape is glued under a layer of plaster, then it must have a special layer that will ensure strong adhesion to the building material. 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.

The question of the need to vapor barrier windows by gluing the joints of window frames and the slope of the outer wall with a vapor barrier tape does not have a definite answer. But having decided to install plastic windows in the house, it is very useful to understand some aspects of the problem:

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

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

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

Vapor barrier is necessary so that moisture from the outside air does not penetrate into the heat-insulating materials of the joint. According to the norms, internal seams for PVC windows should have a vapor permeability of not more than 0.01 mg / m * h * Pa. The vapor barrier is mounted before the windows are installed, sealing the joint from the inside: the window block is installed in the opening without fixing, the areas for gluing tapes are marked, then the block is removed and vapor barrier tapes are glued.

Means for protecting the joints of windows and balcony doors:

Silicone sealants
Insulation with padding - cords, tow, moss
foil tapes
PSUL tapes and tapes based on butyl rubber

For the right choice, it is important to consider the type of window finish and the position of the joint. To protect the joints of frames and plasterboard and plastic slopes (dry cladding) and to protect windows with plastered slopes, various means of insulation are used. For wooden windows installed in log cabins, natural fillers are usually used - sphagnum, jute, linen tow, etc.

Vapor barrier device

There are three layers:

From the inside - thermal protection prevents heat loss from the room to the street
The middle load-bearing insulating layer provides thermal insulation and sound insulation. These tasks are solved by polyurethane foam or other porous material. It is rational to include vapor barrier self-adhesive tapes in this inner layer if the window unit is mounted in wet rooms - kitchens, baths or showers
The outer layer waterproofs the joint and protects against the penetration of cold street air

Vapor barrier tapes are available with a single-sided adhesive layer and double-sided. A one-sided sticker is used if the tape is mounted on the side surface of the window frame. Double-sided tape gives an advantage in the choice of fasteners: on the frame or in the window opening. According to the climatic versions, the tapes are also produced in two types - for areas with low winter temperatures - the winter version of the tape, and for areas where temperatures do not fall below + 5 ° C - the summer version.

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

The main types of vapor barrier tapes:

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

In addition to the main layer of non-crosslinked polyethylene foam, which has a thickness of 2 mm and is waterproofing, the GPL tape has a second layer - both vapor barrier and protective. the thickness of the outer layer is only 20 microns, the material is polypropylene.

GPL tapes are used for all types of door and window blocks as universal. They combine two tasks - waterproofing and vapor barrier. The structure of foamed polyethylene is elastic and closed-porous, so the material does not absorb moisture, hygroscopicity is almost zero. The tapes are flexible and suitable for mounting on uneven surfaces. Metal lamination and the quality of the main polymer (polypropylene as a protective layer) determine the chemical resistance in both acidic and alkaline environments, and as a result, good durability of the HPL tapes.

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

Features of installation of vapor barrier tapes

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

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

Salute, readers!

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

What battles sometimes flare up there!

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

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

If you do not yet know what a vapor barrier tape is, then this topic is just for you.

Welcome!

Vapor barrier tape for windows

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

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

Varieties of vapor barrier tape

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

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

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

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

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

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

To protect the installation seam from high humidity for dry finishing of slopes, there are metallized vapor barrier tapes on the market.

General information on installing vapor barrier tape

Initially, you need to prepare your opening: clean the inner and outer surfaces of the opening and frame from dirt, dust and other debris. The frame is inserted into the opening and is not temporarily fixed.
After gently mark the line on the frame for attaching the vapor barrier tape.
After carrying out the calculations and marking with the window, we remove the frame and glue our internal vapor barrier tapes. We do not remove the paper strip that protects the inner adhesive layer, which later attaches to the walls.

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

Helpful advice!

Therefore, before finishing, moistening and filling with foam, you can remove the protective paper strips from the vapor barrier tapes.

External heat-insulating tapes can be glued no earlier than the complete polymerization of the mounting foam.
Installation of vapor barrier tape under the window sill can be done last. When installing a vapor barrier tape under a plaster layer, the tape must have an outer coating, which will provide the necessary adhesion to this plaster layer.

Installing a vapor barrier tape on windows is installed in a continuous layer along the entire contour of the opening.

Do not forget that the use of finishing building materials in combination with a vapor barrier tape is allowed only if the moisture-permeable characteristics are observed.

Installing the internal vapor barrier sealing tape

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

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

The low weight of the tapes makes them easier to work with during installation, and also significantly reduces transportation costs when transporting tapes over long distances.

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

Cut the tape into pieces with a length equal to the width and length of the window +10 cm (to form corner joints). Docking of tapes along the length is allowed "overlapping", not less than ½ of the tape width.
Remove the protective paper from the vapor barrier tape from the side of the duplicated strip and glue it to the frame profile from the outside.
The tape is fastened by means of a self-adhesive duplicated mounting strip in a taut state (tightly, without folds or swelling) to the outer surface of the box from the inside vertically and horizontally to the ceiling. The inner edge of the adhesive layer must match the inner edge of the frame. The tape protecting the butyl rubber layer is not removed at this stage of installation.

The adhesive strip has a sufficiently high resistance to low temperatures without loss of adhesive properties.

Lack of adhesion can occur if the acrylic adhesive strip is kept in the cold for a long time with the release paper removed.

How to properly apply vapor barrier tape on PVC windows

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

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

Tape with two adhesive strips is very convenient to attach to the window and to the slope. Vapor barrier tapes are divided into summer and winter, depending on the weather conditions in the room.

Summer tapes can be used at air temperatures from +5 to +35C, and winter ones at air temperatures below 0 degrees. The window tape should be chosen so wide that it is 45 millimeters wider than the width of the mounting joint. This will allow you to provide a reliable vapor barrier for the installation seams of your windows.

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

Helpful advice!

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

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