Alumaguard Lite is a 5-ply high strength composite membrane consisting of multiple layers of UV resistant foil and tough puncture resistant polyester. 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.


Alumaguard Lite is designed to be used outdoors to weather-proof exterior insulated ductwork, piping or otherinsulated 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 is not recommended on systems where heavy abuse is expected or on ammonia, brine or glycol systems where expansion and contraction could compromise the acrylic bond to the substrate. Refer to our technical bulletin on this subject.
