Reflective air bubble insulation reflects heat and almost 97 percent of radiant heat rays to keep the inner atmosphere at stable temperature. Such thermal resistant bubble insulation material is actually single or multi layer polyethylene air bubbles film coated with aluminum foil or fibers from single or both of the side. The layers of air bubbles are sandwiched between pure and reflective aluminum material. It gives higher strength to the polyethylene film and also the resistance against the punctures and tears. Such thermal roof insulation material is versatile in use as it can be used to covers the roofs, ceilings, crawl spaces, wall and attics and even utilize for packaging purposes. Such radiant barrier film is also used for mobile house insulation. Large scale steel building and concrete structure can also be insulated with multi layer bubble insulation by pre engineered building insulation. One of the greatest advantages of using thermal resistance polyethylene air bubble insulation is that it can be used again and again as far as it remains in comparatively sustainable shape. Application of polyethylene bubble insulation includes similar to fiberglass application and such material can be used in both hot and cold climates. HVAC ducts, steel structure, garage openings, basement walls and radiant roof can be covered with such insulation material. However, different versions of the product like single layer air bubble insulation or double layer air bubble insulation are recommended for various application based on the climate, material of roof, situation and other details.
