Mineral & synthetic insulation
Description
Rockacier B nu is a single-density stone wool board in compressibility class B, used on non-accessible flat roofs whose deck is made of profiled steel sheeting or timber, beneath mechanically fixed bituminous waterproofing. The declared compressive stress is 50 kPa from 40 to 80 mm and 40 kPa from 85 to 90 mm, for a point load of PL(5)400 N. The declared thermal conductivity λ is 0.039 W/(m·K) and the density 157 kg/m³ at 40 mm then 135 kg/m³ from 50 to 80 mm. The board is non-combustible, Euroclass A1. Seven product codes cover thicknesses from 40 to 80 mm, mainly in 1200 x 1000 mm format with two large formats, 2400 x 1200 and 2400 x 600 mm, for thermal resistances from 1 to 2.05 m²·K/W. The product is covered by a technical application document.
