摘要
Composite sheet material comprising (a) a layer of mineral material, (b) a layer of polyurethane foam and (c) a covering layer. Pref. layer (a) is pref. of rockwool and has a thickness of 10-50 mm and a density of 100-300 kg/per cu.m, (esp. ca. 220). Polyurethane foam layer (b) is pref. 20-120 mm thick and has a density of 20-40, esp. ca. 30 kg/per cu.m. layer of (c) is pref. 0.1-3 mm thick and esp. comprises a layer of glass fibre reinforced flexible material such as bituminised or plastic coated glass fabric.
