Application of external thermal insulation in masonry
Fixing of thermal insulation boards is usually carried out by a combination of gluing and mechanical fixing. For the installation of the first, lower row of thermal insulation boards, starter rails (inverted P-shaped aluminum metal slats) are fixed with broad-headed plugs, around the base of the building and parallel to the ground, which act as guides for their alignment. This is followed by the installation of the heat-insulating plates with special glue and their fixing with plugs, which are inserted into pre-drilled holes. It is good that the fixing plugs enter slightly deeper into the thermal insulation material and are covered with washers of the same thermal insulation material, so as to avoid point thermal bridges in the place of the wires. Then a double layer of acrylic-based organic coating is applied, which has the property of absorbing contractions and expansions without cracking, incorporating a reinforcing glass mesh and optionally a final decorative coating.
