100mm Isover Spacesaver is a glass mineral wool roll of high quality, perforated along the roll to allow the user the choice of full, half or third width options from a single roll. The strong, resilient and flexible rolls are pre-perforated to 3 x 386mm and 2 x 580mm widths to fit between common joist spacing. Isover Spacesaver provides thermal insulation for cold roof constructions in both new-build and renovation projects. Rolls are installed in two layers, the first layer between the joists and the second layer cross laid over the joists.
