Dry dead air is insulation. In fiberglass batts, blown cellulose or foam panels, it's the dry pockets of air that slow the conduction of heat or cold. Heat radiates as well. It's smart to reflect heat radiation - away in the summer or to keep it inside during the winter. Foil and smooth surfaces reflect, but most building designs fail to optimize the control of radiated heat.
ASTRO-FOIL reflective foil insulation consists of two layers of polyethylene bubble film sandwiched between two layers of 99.9% pure aluminum foil, making a structure 5/16-inch thick.
Depending upon the application, ASTRO-FOIL can outperform 6″ of mass insulation in all climates.
ASTRO-FOIL is excellent as a primary insulation for buildings of all types. Preferred by installers and building owners because it is safe to handle, lightweight and works especially well in limited space. There are numerous applications for residential, commercial, industrial and agricultural buildings.
