Enjoy a comfortable space with this AYR-FOIL™ reflective insulation for residential and commercial applications. Designed with a thin and lightweight material, it's easy to handle and install. This reflective foil acts as a vapour barrier by blocking moisture from entering into the wall cavities. It has a protective polyethylene layer that's tough and protects the foil from corrosion. For effective under-the-concrete slab insulation, Ayr-foil absorbs heat from the slab to create a desirable temperature in the room. Made from non-hazardous material, this foil is non-allergic and safe to use. It's resistant to cracks and tears which makes it a durable option. Available in rolls of 48 in x 125 ft, the foil can conform to different shapes and sizes to cover water heating systems. With a washable finish, the aluminum insulation is easy to maintain.
