Alumaguard® Lite is designed to be used outdoors to weather-proof exterior insulated ductwork, piping or other insulated tanks, vessels and equipment or indoors on pipe systems and ductwork where a true zero-perm vapor barrier and durable outer jacket is required. Alumaguard Lite can be used for the underside of the duct and does not require pinning. It is the recommended product to be used on the underside of the duct in Alumaguard® applications. Alumaguard Lite is a zero-perm, multi-ply high strength composite membrane consisting of multiple layers of UV resistant foil and tough puncture resistant polymer. This multi-ply lamination is then coated with a proven cold weather acrylic adhesive to which is applied a heavy-duty kraft liner that gives the membrane its peel and stick functionality. When used indoors, it meets low VOC emissions criteria. It is available in either a smooth silver finish, or an embossed silver surface finish. Alumaguard Lite is a “Peel and Stick” product which must be applied to a properly prepared substrate. In duct applications, it is the recommended product to be used on the underside of the duct and does not require pinning.
