Canadian Metal Building Insulation is a flexible fibre glass blanket insulation furnished in unfaced rolls. Its primary use is in exterior walls and standing seam roofing systems of pre-engineered metal buildings. It is intended to be laminated with an appropriate vapour retarder facing suited to the specific job application and also can be used as an unfaced layer of insulation. Canadian Metal Building Insulation reduces the level of exterior and interior noise by reducing transmission of exterior sound to the interior of the building and absorbing reverberating sounds within the building. Canadian Metal Building Insulation provides thermal efficiency, helping to keep heat inside the building in winter and outside in summer. When faced with a vapour retarder, it helps control condensation on the inside surfaces of the building’s roof and walls.
