About this product
The 170mm Isover Spacesaver Loft Roll Insulation Combi-Cut (8.15m²) is a high-performance glass mineral wool insulation roll designed for thermal insulation in lofts and pitched roof applications. Manufactured with up to 80% recycled glass, this Isover loft insulation helps reduce heat loss and improve energy efficiency within the building envelope. The combi-cut design allows the roll to be easily split to fit common joist spacings, simplifying installation and reducing waste. With a thermal conductivity of approximately 0.044 W/mK and Euroclass A1 fire rating, it provides reliable thermal and fire performance for both new build and refurbishment projects.
