We love this stuff – it’s amazingly easy to work with, and has countless applications for improving energy efficiency around the house. Attics, crawl spaces, walls, water tanks, even garage doors can get a big efficiency boost from a single layer of Reflectix insulation.
Reflectix uses a durable 7-layer construction, made up of a polyethylene core with multiple layers of bubble core for thermal insulation and outer layers of aluminum foil for heat reflection. Fiber-free so it requires no protective clothing during insulation, and easily cut to size for custom fitting.
Reflectix Bubble Pack Foil Insulation (24″ wide, 50-foot roll), $48.37.
