90mm Isover Timber Frame Batt 35 - (Pack of 10) (16 Packs per Pallet)

90mm Isover Timber Frame Batt 35 is a medium density glass mineral wool slab that reduces heat loss through external walls, improving the energy efficiency and carbon footprint of a building as part of two advanced timber frame systems that can meet Part L Building Regulations (England and Wales) and Section 6 (Scotland). Ideal for use in Passive House constructions and buildings with mechanical heat recovery systems, Isover’s timber frame systems can achieve an overall construction U-value down to 0.14W/m²K. Two batts end-to-end typically fit standard storey height. Isover 50mm Timber Frame Batt 35 also has a thermal conductivity of up to 0.035 W/mK when installed on its own.
