Rockplus Premium kraft stone wool insulation board

Description

Rockplus Premium kraft takes the high-performance board from the Rockplus range and adds a polyethylene-backed kraft facing on one side. It is intended for insulation beneath the rafters of converted or convertible loft spaces, and also deals with internal walls, for all types of vertical walls between framing as well as all types of masonry lining walls. The product is suitable for timber frame construction, where it meets the requirements for thermal comfort in summer and winter, acoustic comfort, fire performance, behaviour in the presence of water and moisture, and resistance to pests. The declared thermal conductivity λ is 0.032 W/(m·K) for a density of 65 kg/m³, with an A+ indoor air emissions rating. The kraft facing leads ROCKWOOL to declare the reaction to fire as NPD. Seven thicknesses are listed, from 75 to 200 mm, giving thermal resistances from 2.3 to 6.25 m²·K/W.
