Low-E Insulation PERF
Low-E Insulation PERF is perforated using our patented process. The perforations are designed to allow moisture to pass through the product while limiting air movement. Low-E PERF is recommended for use on the external sides of an insulation system and is certified for use in wall, floor, and roofing applications.
