Facade insulation board for the insulation of external facades of buildings, thermal insulation composite system with such facade insulation panels and method for producing a facade insulation board

摘要

The present invention relates to a facade insulation board (4) for the insulation of external facades (2) of buildings, in particular as a component of a thermal insulation composite system (1), which is formed of bonded mineral wool and a design value of the thermal conductivity lambda 0.040 W / mK in accordance Complies with DIN EN 13162. The facade insulation board (4) has an underlayer (41) and a cover layer (42). The underlayer (41) is formed of laminar mineral wool. The cover layer (42) has mineral wool with increased mechanical strength compared to the backsheet. In this case, the proportion of binder for the first time in the region of a boundary layer between the cover layer (42) and the laminar lower layer (41) is greater than in the other areas. Furthermore, the present invention relates to a thermal insulation composite system with such a new facade insulation board. In addition, the present invention further proposes a method for producing such a facade insulation panel (4).
