The 170mm Isover Spacesaver Loft Roll Insulation is a high-quality glass mineral wool insulation designed for thermal application in cold roofs and loft floors. It provides excellent thermal insulation and is suitable for both new-build and renovation projects.
It is made from lightweight and easy-to-handle glass mineral wool, making it simple to cut and install. The rolls are pre-perforated at specific dimensions to allow for easy installation between joist centers of either 400mm or 600mm. It is recommended to install the rolls in two layers, with the first layer placed between the joists and the second layer cross-laid over the joists.
