Alumaguard Weatherproff Jacketing from Polyguard products, is the original, flexible self-healing membrane used world-wide on exterior ductwork. Used on refrigeration and chilled water piping, tanks, vessels and equipment.
Alumaguard is a composite membrane consisting of a multiply embossed UV-resistant aluminum foil/polymer laminate.To which is applied a layer of rubberized asphalt specially formulated for use on insulated duct and piping applications. The rubberized asphalt acts as the substrate adhesive and provides the self-healing characteristics necessary to seal around punctures. Protecting the rubberized asphalt is an easily removed plastic release liner which gives Alumaguard® its peel and stick functionality.
