A 50mm thick fiberglass insulation bonded on one side to a reinforced kraft/aluminium foil. Manufactured in 1270mm wide rolls with a cover width of 1200mm and in any length from 8 metres up to 25 metres in 100mm increments. Factorylite is the updated and improved version of flexible building insulation. Factorylite is manufactured from high quality non-combustible flexible Glasswool insulation with an inert binder, which makes the product lightweight, safe and resilient. Factorylite is faced on one side with either a reinforced foil, white metalized foil or black metalized foil.
