Toitrock kraft stone wool insulation roll

Description

Toitrock kraft comes as a stone wool roll faced with polyethylene-backed kraft fitted with side tabs. These tabs are used to staple the roll to the roof timbers and to overlap the adjacent widths, which makes installation continuous without any additional accessory. The product is intended for insulation beneath the rafters of converted or convertible loft spaces, in refurbishment. It is offered in a single thickness of 70 mm, for a thermal resistance R of 1.75 m²·K/W, in 7 m lengths and three widths of 350, 450 and 600 mm. The declared thermal conductivity λ reaches 0.040 W/(m·K) for a density of 23 kg/m³, with an A+ indoor air emissions rating. The kraft facing leads ROCKWOOL to declare the reaction to fire of this composite as NPD, performance not determined.
