Edge insulation strips are primarily used to prevent sound transmission from the floor to the walls (sound bridges) in the case of floating screeds. They are located between the screed and the wall and ensure the decoupling of the two components.
Screeds are surrounded by edge insulation strips, with the height depending on the structure of the covering construction. Here, the insulation strips are placed first, then the screed is placed and finally the protruding insulation strips are cut off at the upper end. The upper end is formed by an elastic movement joint, which is usually used after the floor covering has been laid.
Edge insulation strips can be made of insulation materials such as polyethylene, mineral wool, etc. They are offered on rolls, in thicknesses of 5, 8 and 10 mm and in heights of 100, 120 and 150 mm.
insulation strips are particularly necessary for heated screeds, as this allows the screed to expand without cracking.
Edge insulation strips also serve to protect the screed and the floor covering from moisture from the wall. At the same time, they also protect the wall from moisture from the room.
The height of the edge insulation strips must be 10 to 15 mm higher than the later screed height during installation.
