FACADE INSULATION BOARD FOR THE INSULATION OF EXTERNAL FACADES OF BUILDINGS, COMPLETE THERMAL INSULATION SYSTEM INCLUDING SUCH FACADE INSULATION BOARDS AND METHOD FOR MANUFACTURING A FACADE INSULATION BOARD

摘要

The present invention concerns a facade insulation board (4) for the insulation of external facades (2) of buildings, in particular as a constituent of a composite thermal insulation system (1), which is formed of bound mineral wool and satisfies a rated thermal conductivity value X 0.040 W/mK according to DIN EN 13162. The facade insulation board (4) comprises a bottom layer (41) and a top layer (42). The bottom layer (41) is formed of laminar mineral wool. The top layer (42) includes mineral wool having an elevated mechanical strength in comparison with the bottom layer. Here for the first time the binder content is higher in the area of a boundary layer between the top layer (42) and the laminar bottom layer (41) than in the other areas. Moreover the present invention concerns a composite thermal insulation system including a like novel facade insulation board. The present invention furthermore proposes a method for manufacturing such a facade insulation board (4).
