Damper tape, which is also called compensatory or edge tape, is used to fill expansion (temperature) and dilatometric joints of various types of self-leveling, industrial and underfloor heating structures. It is designed to isolate noise, eliminate vibration transmission, thermal insulation between floor and wall. Since the damper tape includes a filler that remains elastic for a long time, it is suitable for compensating the stress of the floor that occurs when the temperature changes, which is accompanied by contraction or expansion. Irreplaceable damper tape for floor screed (pouring mix). It prevents it from cracking during drying and contributes to the acquisition of strength.
The damper tape is made from high quality polyethylene foam. It has a so-called "protective apron", which is designed to seal the gap between the surfaces and the tape. It also protects it from the effects of various building mixtures. This tape has a low thermal conductivity and a high levelmoisture and sound absorption. Damper tape is a durable and economical material. It is often used for sealing gaps, sealing joints. This consumable will not warp, rot or be mold infested.
The damper tape is mounted in different ways, it all depends on the purpose of its use. Most often it is used for underfloor heating. Since the concrete screed of such a coating has an expansion coefficient of about 0.5 mm / m, when installing it, it is necessary to prevent any possibility of cracking and pressure on the walls. In this case, its installation begins with the laying of a damper tape along the walls of the entire room. It plays an important role as a compensator. The cuts on it should be directed upwards (to facilitate separation), and the film - downwards (toward the floor). This tape is also laid along other architectural elements of the room, such as columns. If the area of the room is very large, it is necessary to provide for laying additional expansion joints. This tape is placed so that its upper edge protrudes slightly beyond the floor level. After laying floor materials, the protruding part is cut off. Upon completion of the installation, the excess damper tape is torn off along the notch, and its visible part is covered with skirting boards. This consumable building material provides excellent floor insulation, reducing heat loss through walls.
Because the underfloor heating damper tape is made of high quality polyethylene foam, it is safe for human he alth andanimals. With proper operation of underfloor heating, its service life is practically unlimited. When using this material, it should be taken into account that during the "linear expansion" of the screed, the area of \u200b\u200bthe room on the first layer of the tape should not exceed 10 m. If this area is larger, it is necessary to provide additional tightness at the joints. When buying this consumable, you should pay attention to the presence of a special “scale”, which makes it easier to cut off excess that exceeds the level of the screed.
