MicroFoil insulation is a clean, non-toxic, self-taping reflective foil insulation and vapor barrier that provides increased comfort, energy efficiency, and a clean finished appearance. MicroFoil reduces heat gain and loss by reflecting radiant energy, the predominant form of heat transfer. MicroFoil insulation does not contain hazardous chemicals or materials that can cause itching or allergic reactions. It is made from a proprietary blend of high-purity aluminum foil incorporating a moisture-proof thick multi-ply core. To make installation fast and easy, every roll of MicroFoil has a patented self-taping flange running along one edge, eliminating the need and the extra cost of seaming tape. All that is needed to install is a utility knife, staple gun, and eye protection.
