AtticFoil Single Sided Radiant Barrier Foil Insulation is designed to help block radiant heat and improve building energy performance. This 60-inch wide roll delivers 1,000 square feet of high-quality reflective coverage for attic and wall applications. The reflective aluminum foil surface reduces heat gain by reflecting radiant energy away from living spaces. The aluminium foil sheet is reinforced for durability, providing strength and reliability during installation. Ideal for use as a house wrap, though radiant barrier can also be used in attics, as roofing underlayments, and in crawlspaces. This radiant barrier also provides moisture resistance during new construction and remodeling projects as it sheds water. Lightweight and easy to handle, this aluminum foil insulation roll installs efficiently while delivering long-lasting thermal and weather protection.
