Installing FiberGlass Building Insulation is an easy, cost effective method to help conserve energy in residential and commercial new construction, remodeling, and re-insulation. In addition to its thermal properties, FiberGlass Building Insulation provides excellent acoustical performance. The material is compression–packaged for ease of handling, and its broad availability of R-values, sizes and facings ensures the right product for the job.

CertainTeed Fiberglass

A high-quality fiberglass batt or roll used in residential construction for thermal and acoustical insulation of walls, ceilings and floors. Unfaced insulation is manufactured in increased widths to permit friction-fit installation in wall cavities. This insulation is used with a separate vapor retarder, such as CertainTeed’s MemBrain™, The Smart Vapor Retarder, or where a vapor retarder is not required. Kraft Faced insulation is manufactured with an integral vapor retarder. The Kraft facing includes attachment flanges at the edges that are used for either face or inset stapling. The Kraft facing, applied with asphalt to the fiberglass insulation, has a vapor transmission (permanent) rating of one perm or less.
