Fibre-gypsum board has excellent insulation characteristics of airborne sound. Regarding thermal insulation, we use extruded polyester, of high hardness, at least 2 cm thick with a coefficient of λ=0.033 W/mK.
Various high hardness insulation solutions (extruded polyester XPS 200) are proposed. The proposal is extruded polyester XPS 200, 2 cm thick, with λ=0.033 W/mk.
The total height in new constructions when tiles are used is 4.7 cm (2 insulation, 1.5 cm fiber plasterboard, 0.6 cm glue & 0.6 cm tile).
