Rockacier C nu stone wool flat roof insulation board

Description

Rockacier C nu is a single-density stone wool board in compressibility class C, used on non-accessible flat roofs with a profiled steel or timber deck, beneath fully torch-bonded bituminous waterproofing. It is optimised for plant areas and for green or photovoltaic flat roofs, where imposed loads and maintenance traffic are higher: the compressive stress reaches CS(10/Y)70 kPa. The declared thermal conductivity λ is 0.042 W/(m·K) at 50 and 55 mm then 0.040 W/(m·K) from 60 to 160 mm, for densities of 175 and 145 kg/m³ depending on the thickness. The reaction to fire is A1. Twenty-five product codes cover thicknesses from 50 to 160 mm, in 1200 x 1000, 2000 x 600, 2400 x 600 and 2400 x 1200 mm. The product is covered by a technical application document.
