Sloping roof system and insulating board for sloping roof systems

Abstract

The invention relates to an insulation panel ( 6 ) for a sloping roof system, comprising an insulation body having a planar base and a surface as well as lateral surfaces ( 14 ) connecting the base to the surface, wherein the base is directed anti-parallel with respect to the surface, so that the surface is at least inclined with respect to the base, wherein the insulation body is designed in a sandwich fashion and includes at least a first layer ( 11 ) having heat and/or sound insulation properties, particularly from mineral wool, preferably from rock wool. To provide an insulation panel ( 6 ) for a sloping roof system with improved mechanical properties, so that the panel can resist high pressure loads and shearing stresses on the one side and is suitable for forming a kit for a sloping roof construction on the other side, it is proposed that the first layer ( 11 ) is connected to a second layer ( 13 ) having mechanical properties, particularly a pressure strength and/or bending strength, different from those of the first layer ( 11 ) and consisting of a material which is different from the material of the first layer ( 11 ) and at least has a higher bending stiffness.
