SmartFOIL is a solid radiant barrier sold as a roll. It is a two-sided reflecting metalized film reinforced with polyethylene weave. It reflects up to 95% of radiant heat.
The material is light and strong. It cuts with scissors and staples to attic rafters, floor joists or walls without special equipment. When properly installed, it performs at an R-18 equivalent.
It helps keep a building cooler in summer and retain heat in winter. It suits attics, walls, crawl spaces, barns and metal buildings.
