This tape is a strip made of polyethylene foam. As a rule, it is equipped with a protective apron and a self-adhesive layer covered with a thin polyethylene film. Typically 100 or 150 mm wide, 8 or 10 mm thick and available in rolls of 25 or 50 m, but other sizes may be available. A damper tape is used for floor screeding and performs a number of functions.
Its main purpose is to compensate for temperature fluctuations (the German word Dämpfer is a muffler), absorbing sound waves and vibration. In addition, it plays the role of a seal and additional thermal insulation of the floor from the adjacent external walls. When the screed area is large, the damper is used as an expansion joint to prevent cracking. Like any consumable building material, it is used once.
Characteristics
Most often, edge tape is used around the perimeter of the room and as a separator when there is a large surface area of the screed. A strip 100 mm wide is used for single-layer and double-layer screeds, consisting of a leveling layer and a thin finishing layer.
A damper with a width of 150 mm is used when laying multi-layer and prefabricated structures, on thermal insulation layer containing a separating layer. Edge tape is also used to screed heated floors, since such a surface has a relatively large thickness. In cases where a screed of less than 50 mm is planned, a damper, as a rule, is not used.
A damper tape is installed around the perimeter of the screed, therefore, first you need to clear the room of construction debris. This is done so that the self-adhesive surface remains suitable for use after removing the protective polyethylene film from it.
It is best to gradually release the adhesive layer and press the tape tightly against the wall, sequentially unwinding the roll: the fewer connections, and they are made overlapping, the better.
Many manufacturers produce edging tape with longitudinal (horizontal) notches along one edge, which simplify the subsequent trimming of excess strip protruding above the screed. It is necessary to ensure that the notches are at the top. The protective apron should be turned downwards - towards the floor, then the liquid solution will not flow under the tape fixed along the wall.
Since damper tape is used to compensate for thermal expansion and thermal insulation concrete screed, then you should also take into account the area of the room and its shape. The maximum permissible area of a continuous screed should not exceed 40 m2 with an aspect ratio of 1:2, the length of the wall should not exceed 8 m. If the room is U-shaped or L-shape, then the screed should be divided into rectangular (or square) fragments, separated from each other by expansion joints. Each doorway must have the same compensator in its lower part. Tape that can be installed perpendicular to the base and secured with mounting angles, and will further serve as an expansion joint.
After pouring the screed, the edge of the edge should protrude approximately 20 mm above the surface. Cut off excess damper in expansion joints before installation tiles, parquet, linoleum and the like. The protruding edges of the tape installed along the perimeter of the walls are removed after laying the floor covering and covered with baseboards.

When compiling construction estimate Some customers sometimes try to save money and try to use other materials instead of damper tape. In most cases, such diligence has undesirable consequences. Regular foamed polyethylene, sold in wide rolls, will be cheaper, but it still needs to be divided into strips of the required width, and then secured with glue or self-tapping screws with plastic heads, this will lead to additional time.
Foam plastic does not return to its original state after deformation. The width of penofol and isolon should also be reduced; in addition, they are not resistant to moisture penetration, poorly dampen noise and vibration, and are also expensive. Wood slats require adjustment to required size, absorb moisture, after which fungus grows on them, they can be a haven for insects and are significantly inferior to foamed polyethylene in many respects.
As a result, it turns out that there is still no adequate replacement for the damper tape. And reasonable costs for quality consumables will pay off handsomely. Especially if, instead of gaining personal skills in construction and installation work, you invite a team of qualified specialists.

Many are perplexed and frightened when they come across new technologies or building materials, both basic and auxiliary. One of these is a material with the mysterious name damper (edge) tape, which has recently appeared on the shelves domestic market. You can learn more about what it is from our article.
In principle, edge tape cannot be classified as a newfangled invention; it’s just that in the form in which it appears to the consumer now, damper tape appeared relatively recently. Previously, any elastic insulation was used for the same purposes.
Edge tape for floor screed is necessary to provide compensation loads in places where the floor covering deformation interfaces with the enclosing and load-bearing structures of the building (walls). Polymer damper tape can be laid around the perimeter of a small room and, if the floor area is large, further divide it into small sections.
Edge tape is used when performing:
Compensation polymer material is produced in the form of a tape with a width of 50 and 100 mm, a thickness of 8-10 mm, a length of 20 m, usually in a roll. The damper tape is made from porous-fiber or foamed polymer materials.
Foamed polyethylene used to produce damper strips has a number of positive characteristics:
In addition to the main task - to compensate for possible loads, protecting floors from destruction due to temperature deformations and building settlement, the damper tape also performs the following functions:
By using edging tape when installing floors, you also protect the finish. flooring("carpet" from ceramic tiles, parquet, marble) from cracking and deformation. It serves as a shock absorber between the wall and the floor screed and remains elastic throughout its entire service life without losing its compensatory properties.
When carrying out work on installing or repairing floors with your own hands, be sure to use a damper tape, especially since its price cannot be compared with the benefits of its use. Everyone will choose a ribbon that suits their pocket.
Cost of a twenty-meter roll of edgebanding from different manufacturers:
Knauf edge tape, from a famous manufacturer building materials, a similar format retails for about 260 rubles. This compensation material works perfectly in prefabricated floors with so-called dry screed. This refers to the rough covering of the floor over the thermal insulation layer moisture resistant sheets drywall from the same manufacturer.
Note! Tape prices may vary slightly depending on your region.
When installing a “Warm Floor” water system, an edge strip 150 mm wide and 5-10 mm thick is used.
Instructions for using edge tape from manufacturers give the following recommendations:
This is done before starting work on the floor. The tape should rise above the finished level finishing coating floor by a few millimeters.
Important! To ensure that the self-adhesive edge tape is applied thoroughly, the following must be observed: simple rules. Firstly, the base must be dry and dust-free, secondly, the strip must be pressed tightly to the surface, and thirdly, the damper tape must be stored in dry rooms at room temperature.
Advice! When laying ceramic tiles, the edge can be cut off only after grouting the tile joints.
The need to use damper tape is justified; as you already understand, it is used for a variety of purposes. However, if you look from the other side, they used to cope without it, and they didn’t seem to feel any difference.
In fact, the decision to use the tape or not is up to you, but its cost is so insignificant that it would be wrong to refuse such a “multifunctional gadget.”
In the video presented in this article you will find Additional information on this topic.
On modern market The widest range of building materials from both domestic and imported manufacturers is presented. Thanks to such a variety of options, potential consumers can choose the most suitable materials for repairs.
IN Lately Dry screed technology, which involves the use of edge tape, has become significantly widespread in the organization of floor coverings. Edge tape should not be considered a new invention. It’s just that in the form in which it is used today, the tape arose not so long ago. But before the advent of the damper strip, builders used ordinary elastic insulation when organizing the screed.
The main purpose of this element is to provide compensation loads that arise when interfaced with load-bearing or enclosing surfaces. If the area of the room is small, then the tape is laid around the perimeter of the room. Otherwise, it can be divided into certain areas.
In the manufacture of strips, foam or fibrous materials are used polymer materials. The width of the strip is from 50-100 mm, the thickness is from 8-10 mm, and the length is 20 m. As a rule, it is sold in rolls. 
The material used in the manufacture of the damper strip has a large number of good performance and quality characteristics: flexibility, tightness, strength, long service life. In addition, it has low thermal conductivity, and is also water-repellent and sound-absorbing.
Modern damper tape perfectly compensates for vibrations and retains its original structure and shape during operation. Possesses high level resistance to negative impact chemical and biological substances. It is very easy to install; not only a professional, but anyone can do this work on their own.
As mentioned above, edging tape is designed to accommodate various loads on the floor covering. In addition, it protects the surface from destruction during building settlement and temperature changes. There are a number of other functions that edging tape can handle:
By using edge tape when arranging floor coverings, you can ensure reliable protection for finishing coating against unwanted deformation and cracking.
The edge tape for floor screed acts as a kind of shock absorber located between the floor and the wall. Over a long period of time, the tape will retain its excellent original properties without losing its elasticity.
Experienced specialists recommend that workers carefully study the subtleties and nuances of this type of work before starting to lay screeds and edge strips. On all structural elements that are ascending, the floor level should be noted. The tape should be installed around the entire perimeter of the room, avoiding any breaks. Protective film, located on the tape, should be removed and placed with the adhesive side to the wall. If necessary, the edges of the two tapes can be joined with a slight overlap.
All of the above steps must be completed before starting work on installing the flooring. It is worth noting the fact that after installing the finishing coating, the tape should rise by several millimeters. If you correctly perform all the above nuances, the result will exceed all expectations. Finished design will serve its owners well for decades. 
Sometimes situations arise when the tape with an adhesive layer does not fit tightly enough to the wall. In order to avoid such situations, you should take into account some features of its use. The base on which the adhesive tape will be applied must be degreased and dried. The strip should be pressed quite firmly against the wall. To store the tape, use dry rooms at room temperature.
3925 03/08/2019 4 min.When you start renovating your apartment, you have a question about how to properly screed the floor so that it can withstand the load. There is a solution - using a damper tape. You can purchase such a product at any hardware store at a competitive price. Like any material, damper tape is characterized by its advantages and disadvantages.
Everyone still knows from their physics course that when they heat up, bodies expand, and when they cool, on the contrary, they contract. This statement is also true for repairs. If you are screeding a floor, you want to end up with a perfectly smooth coating that is not subject to deformation. So, what are the benefits of using damper tape?
Thanks to this product, it is possible to prevent damage to the screed and walls of the room, as it can withstand the pressure of concrete. This material acts as a layer that creates a protective layer from the effects of temperature fluctuations, creating compensation for the joints. In addition, it is considered an excellent sealant and sealant for cracks.
You can learn about this from the description in the article.
You can also highlight the following advantages of this product:
In the video there is a damper tape for the screed:
All the described qualities of foamed polyethylene allow the use of damper tape when sealing cracks and spaces that arise during construction.
Very often such material is called compensatory or edge material. The tape is sold in rolls. Their length is 10-100 m, width – 5-15 cm, thickness – 3-10 mm.
When it is manufactured at the factory, cuts are made along its entire surface in increments of 8-10 cm. Thanks to them, it is possible to eliminate the extra protruding edges of the tape when the floor screed is already completed. 
To obtain this material, manufacturers use high-quality polyethylene foam. Naturally, the price of such a product is slightly higher than that of other auxiliary materials. During operation, it is not subject to rotting, deformation and is damaged by the harmful effects of fungus. Thanks to the polyethylene foam used in the manufacture of the damper tape, it is installed simply and quickly.
Once you have determined the need to use the product, you need to understand how to use it correctly.
The installation process must be carried out along the entire perimeter. It is also necessary to pay attention to all architectural elements, if they occur. These include partitions or columns. When laying the material, it is necessary to take into account the size of the area on which the screed was installed. If the area is large, then you should take care of laying additional expansion joints. One layer of the product with linear expansion of the loaf can reach 10 m of screed.
The installation process is carried out slightly above the screed filling level. When the tape is completely dry, the excess parts should be cut off using construction knife. When the screed will be laid decorative covering, and on the walls there is a plinth covering the protruding part of the tape, then the best option would be to cut it off.
Damper tape is very important element when pouring wet screed from cement. It will not only compensate for expansion, but also create a protective barrier that will not allow the solution to spread to the sides.
The video explains whether a damper tape is needed for a floor screed:
When installing a water- or electric-type heated floor, the tape can be installed under the vapor barrier layer or between the heated floor structure and the vapor barrier. You choose the installation method yourself, since there are no restrictions here. In this case, it is very important that the “skirt” of the tape is located under the screed or self-leveling floor. The best option the fastening of the products will become after it has been laid waterproofing material onto the rough surface.
Only a steam room installation of the presented product will allow you to achieve the desired result. Then the damper tape will fulfill specific obligations. To install it, you must adhere to the following action plan:
The video explains how to install a damper tape for a screed with your own hands:
IN construction stores damper tape is presented in a huge assortment, including in the store Leroy Merlin. Anyone can purchase this product various sizes, excellent quality and at a reasonable price. As a rule, the cost depends on its size. Therefore, before going to the store, make all the calculations so as not to overpay on unnecessary material

Damper tape is a very useful and necessary product in construction. Thanks to her, I can teach perfectly smooth screed and save your time on construction work. When choosing this product, carefully study all its characteristics to understand the advisability of using a damper tape.
To compensate for the thermal expansion of the screed, builders lay special materials between the walls and the concrete base. The means used not so long ago had certain disadvantages. However, it is better to avoid mistakes during the construction process. Therefore, today more and more new materials are being developed to compensate for thermal expansion. Many have already been tested and are widely used in modern construction. Today, damper tape is increasingly used for screeds.
This material is used quite often. However, many developers want to figure out whether damper tape is needed for floor screed in any case? This question can be answered only after considering the main characteristics and properties of the product.
Before understanding the features of using damper tape, it is worth understanding what it is. You should also find out what happens during temperature changes.
When heated, the cement layer begins to expand. Due to this, the dimensions of the base change. Simple cement strainer expands by 0.5 mm/linear. m. Such indicators require the use of compensation material.
As a result of expansion, the screed begins to exert strong pressure on the walls. This leads to the creation of serious stress and, ultimately, to the destruction of the foundation and walls. As a result, cracks appear in the floor.
If there is enough space between the walls and the floor long distance, such consequences can be avoided. It is better to use damper tape for floor screed. Many developers replace it with isolan and linoleum. Also sometimes used for this purpose wooden blocks. Each of these materials has certain disadvantages. As an example, the following facts can be cited:
In addition, wood does not have sufficient elasticity to absorb pressure well. The only disadvantage that damper tape has is its high price. The effectiveness of using such a material is determined by its properties.
If it is not possible to use a ready-made compensator, foamed polyethylene should be placed instead. The strips should be cut so that their size matches. They are fastened with self-tapping screws with plastic caps.
The advantages of the tape include the presence of many technical characteristics. Among them it is worth highlighting:
In addition, this material is characterized by a high degree of environmental friendliness. For this reason, it is absolutely safe when used in living rooms.
The compensator may have various characteristics, which depend on its type. There are several varieties of it:
Tapes are usually sold in rolls. Their width varies from 50 to 150 mm. The thickness of the material is about 0.3-1 cm. Such a spread requires careful selection of the product for specific operating conditions.
The upper part of the product has notches, which are applied in increments of 0.8-1 cm. This is necessary to increase ease of installation.
How much edge tape is needed for floor screed is worth finding out in more detail. For screed, it fits in any case. With self-leveling floors things are usually different. The operation of the damper tape is related to the design features of the floating screed. Self-leveling flooring is a contact type of leveling. That is why tape is not always used in this case.
In addition to the main function of the tape, it also acts as a restraining barrier when the solution spreads. The compensator is also used in the construction of the blind area. During temperature fluctuations, the ground beneath it begins to move. As a result, the concrete base may crack. For this reason, damper tape should be placed in the seam.
The same applies to sedimentary seams. The material is able to fill extra gaps. It absorbs various vibrations, which will affect vibration compensation.
The installation process of the damper tape is quite simple. The work is carried out in accordance with the following stages:
Sometimes the tape does not adhere completely. This is usually due to manufacturing defects in the material. The base on which the tape is mounted. It is necessary to carefully level, dry and degrease.
There are several features of the damper tape:
If, after laying the decorative covering, it is decided to install a plinth, the protruding part of the tape is not cut off. Using these tips when installing the damper tape, you can install it correctly. It is also worth understanding the characteristics different types tapes.
To properly fill the screed, you should think about the intricacies of filling the gap between the walls and the base. This will ensure a long service life of the structure as a whole.
