This block is mounted during the process of covering the walls with insulation due to the fact that it must be glued to the surface of main wall. The block with embedded junction box is 200 mm deep and allows for adjustment of its depth in the range 80-200 mm, depending on the thickness of the insulation. For this purpose, the bottom part of polystyrene is appropriately cut. Wall mounting is carried out by gluing the EPS20 block to the wall surface, preferably using a special adhesive (251-KL) or other construction adhesive. Subsequently, it is enclosed by insulation and creates compact solid structure with the wall. In additiona, it includes a pad for fixing elements on the surface of the polystyrene, e.g. cameras, sensors, antennas, etc. Mounting adhesive 251-KL, bearing capacity 12 kg.
