The invention relates to an insulating board (6) for a sloping roof syste m, with an insulating material body which has a flat base surface and a top surface and also side surfaces (14) which connect the base surface to the to p surface, wherein the base surface is oriented anti-parallel to the top sur face such that the top surface has at least one inclination in relation to t he base surface, wherein the insulating material body is of sandwich-like de sign and has at least one first layer (11) with heat- and/or sound-absorbing properties, in particular of mineral wool, preferably of rock wool. In orde r to provide an insulating board (6) for a sloping roof system, which board has improved mechanical properties such that it firstly can resist a high co mpressive and shearing stress and secondly is suitable for the formation of a sloping roof system and of a kit associated therewith, it is proposed that the first layer (11) is connected to a second layer (13) which has differen t mechanical properties, in particular compressive strengths and/or flexural strengths, from the first layer (11) and is composed of a material which di ffers from the first layer (11) and has at least greater flexural rigidity.
