Abstract: A facade system with a translucent porous insulating material of mineral or organic fibers for passive solar energy utilization is provided. The insulating material has on the outside a colored layer for design purposes and for controlling the light transmittance. The facade system is formed from a multiplicity of preferably factory-prefabricated facade insulating boards. The colored layer can, moreover, be designed in such a way that it protrudes beyond the insulating layer along two board edges. Consequently, when the facade insulating boards are applied to the building wall, the abutting edges in the region of the joins between neighboring insulating boards are covered by the overlapping protruding colored layer.

Abstract: The present invention relates to a façade system with a translucent porous insulating material of mineral or organic fibers for passive solar energy utilization, the insulating material having on the outside a colored layer (2) for design purposes and for controlling the light transmittance. The façade system is formed from a multiplicity of preferably factory-prefabricated façade insulating boards (1). The colored layer (2) can, moreover, be designed in such a way that it protrudes beyond the insulating layer along two board edges (3, 4). Consequently, when the façade insulating boards (1) are applied to the building wall, the abutting edges in the region of the joins between neighboring insulating boards are covered by the overlapping protruding colored layer (2).

Abstract: From a mineral fibre strip supplied in roll form, portions (L) are cut off, the length of which corresponds to the width of a rafter area between rafters plus an oversize designed to produce a clamping effect. Formed in this way, the mineral fibre panels are so inserted into the rafter area that the lateral edges of the mineral fibre strip form the top edge and the bottom edge of the panels. In this way, it is possible to achieve virtually completely wastage-free roof insulation even when the distances between the roof rafters vary considerably, and it is possible to work with material of one uniform and considerable width which is supplied in the form of rolls. By reason of the considerable width of the mineral fibre strip, insulation of one rafter area over its entire length requires only a few mineral fibre panels, with few joints being produced.
