This upgrade product consists of a double layer of polyethylene bubbles that are sandwiched between two layer of pure aluminum foil. This wonderful product is Eco-friendly and contains no harmful substances. Compare with the traditional insulation materials, it is fiber free, no airborne particles, non itchy and non cancerous. It is easy to install for homeowners and professional installers. Two outer aluminum layers reflect up to 97% of radiant heat away from a structure on the outside and back into a structure from the inside. Therefore, it works effectively in both hot and cold climates. Two inner layers of insulating bubble pack resist conductive heat flow as well as giving high reliability and strength. The added thickness of bubble creates a more substantial barrier between volatile outside elements and the comfort of those within a building.
