External contact thermal insulation system for walls of buildings containing at least a thermally insulating layer and a visual facade layer. The insulator comes in the form of rigid polyurethane sheets (3), thickness from 10 to 180 mm, with a bulk density of 30-60 kg/ m3, which glued to the wall (1) by means of a diffusion-permeable adhesive cement (2) with an admixture of polyurethane fraction of up to 1.5 mm. From the outside, the layers are provided a diffusion- permeable levelling cement (4) with an admixture of polyurethane fractions of up to 1.0 mm, applied through a mesh (5) of glass fabric with a surface density of 140-320 g/m2. The layer of levelling cement is applied a bonding primer (6) and a layer of visible silicone or silicone-silicate or silicate plaster (7). Adhesive cement (2) and levelling cement (4) have a bulk density of 1100-1200 kg/m3. The visible layer of plaster (7) contains grain sizes of 1.0 to 3.0 mm. Adhesive cement (2) and levelling cement (4) contain polyurethane fraction of at least 3.5% of volume. Other anchoring elements include: disc dowels (8) and/or supplementary bonding. |
