Mineral & synthetic insulation
Description
Rockfaçade Premium is the high-performance version of the ROCKWOOL façade board, intended for external wall insulation behind rainscreen cladding with a ventilated air cavity. Its declared thermal conductivity λ of 0.032 W/(m·K) makes it possible to reach a given thermal resistance with a smaller thickness than the standard version, which limits the offset of the secondary framing and the cantilever of the fixings. The density is 65 kg/m³ and the board is semi-rigid under the ACERMI criterion. Eight thicknesses are listed, from 80 to 200 mm in 1350 x 600 mm, for thermal resistances from 2.5 to 6.25 m²·K/W. The product is non-combustible, Euroclass A1: it is to be distinguished from the notion of combustible material defined by the fire safety regulations applicable to façades, its mobilisable combustible mass being considered as zero.
