Mineral & synthetic insulation
Description
Rockfleece B Energy is a dual-density stone wool board faced with a glass tissue, whose higher-density upper face is identified by a marking. Its compressibility class is B. The glass tissue allows the bituminous waterproofing to be fully torch-bonded onto the board. The product insulates non-accessible flat roofs on a profiled steel or timber deck. The upper layer reaches 180 kg/m³ and the lower layer 100 kg/m³ from 100 to 260 mm, for a compressive stress of CS(10/Y)30 kPa and a point load of PL(5)450 N. The declared thermal conductivity λ is 0.036 W/(m·K) and the reaction to fire A2-s1,d0. Ten product codes cover thicknesses from 100 to 250 mm in 1200 x 1000 mm format, for thermal resistances from 2.75 to 6.9 m²·K/W. The product is covered by a technical application document.
