Product Description
Installing a radiant barrier is the only way to effectively block the transfer of radiant heat. Used as a standalone product in some applications or in conjunction with other types of insulation these reflective foil insulation products are extremely effective. We supply a wide variety of foil insulation products to complete any project.
Our Foil / Double Bubble / Foil Staple Tab Insulation product consists of a double layer of polyethylene bubbles sandwiched between two highly reflective aluminum surfaces. The Staple Tab design is a built in extra edge on both sides of the product, similar to the tabs on faced fiberglass insulation. The purpose of the Tabs is to allow the product to be installed quickly in wall, ceiling, or joist bays. The size of the products offered reflects this, ranging from 16, 18, or 24” wide. The purpose of the product is to reduce the amount of radiant heat transfer in residential and commercial buildings. All products in this class are Class 1 / Class A Fire Rated in compliance with the ASTM E84 fire test standard. In addition to increasing thermal resistance, all of our bubble core products are approved vapor barriers. Because the roll sizes are smaller, they also ideal for smaller projects when 500 square feet or more is not required.
Radiant Barriers are useful anywhere insulation is useful. To understand why they are effective insulators you must understand the two modes of heat transfer and how they work. Heat travels in your home by a mixture of conduction, convection, and radiation. Fiberglass, cellulose, rock wool, and spray foam are all designed to stop the flow of convective and conductive heat. Although each of these insulation types is important and effective, they are not designed and therefore poor at stopping the flow of radiant heat. The two best insulating materials on earth to block radiant heat is gold followed by aluminum. This is why reflective foil insulation and radiant barrier technology exist and are now commonplace in today’s insulation system.
