150mm 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.

Isover glass wool insulation is manufactured from a combination of silica sand and up to 80% recycled post consumer glass from building regeneration projects or flat glass manufacture that would otherwise go to landfill.
