Mineral & synthetic insulation
Description
Rockcomble Evolution is a single-density stone wool board designed to insulate converted or convertible loft spaces, both between and beneath the rafters. This dual position makes it possible to deal with both the main layer and the thermal bridge of the roof structure using a single product, with substantial thicknesses of 200 and 231 mm offering thermal resistances of 6.05 and 7 m²·K/W. Installation relies on the hangers dedicated to the range. The board is semi-rigid under the ACERMI criterion, with a declared thermal conductivity λ of 0.033 W/(m·K) and a density of 50 kg/m³. It is non-combustible, Euroclass A1, and carries an A+ indoor air emissions rating. Three widths are offered, 400, 500 and 600 mm, to suit the rafter spacings encountered. The product is eligible for the Rockcycle take-back service.
