Abstract: The present invention relates to a three component composition consisting of a polyol component (A) comprising at least two polyols, one with high and one with low molecular weight, and water, a polyisocyanate component (B) comprising a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2.5, or a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2 and at least one further polyol with an amount of between 1% and 30% based on the weight of said polyisocyanate component (B), wherein said MDI product and said polyol have reacted at least partially, and a powder component (C) comprising at least one hydraulic binder, preferably cement and/or calcined paper sludge, preferably a calcium compound selected from calcium hydroxide and/or calcium oxide, and optionally one or more aggregates.

Abstract: The invention provides an insulated roof lining consisting of rectangular roofing boards supported on rafters with each board consisting of a hard covering plus a loose insulation layer connected therewith plus a reinforcing body embedded in the insulation layer and firmly connected with the covering. The covering projects laterally, at two sides starting from a corner of the layer, beyond the edges of the layer and partly overlaps the adjoining roofing boards.
