Thermal EPE Laminate can provide R-Values as high as R-17 for specific applications based on heat flow directions and enclosed air spaces. Thermal EPE Laminate consists of one or two layers of FOAM or BUBBLE material laminated between Single or double layers of aluminum foil to provide excellent thermal resistance. they can reflect up to 97% of radiant energy in addition to resisting conductive and convective heat transfers thus providing effective insulation. function. Insulation Material is an ideal for roof, wall, floor, attic, crawl spaces, radiant floor heating, and basic floor heat retention applications as well as for insulating pole barns, post frame, and metal and steel buildings.
