GreenStuf® ADW insulation is a lightweight, flexible, acoustic/thermal insulation material, manufactured from thermally bonded polyester with a fire compliant e-foil laminate facing on one side. ADW is used for external wrapping of air conditioning Sheetmetal ductwork. It provides noise absorption and thermal insulation for the ducting. ADW also acts as a moisture barrier preventing condensation on cold air systems that could otherwise lead to corrosion and staining of ceilings if not insulated. ADW is designed to be easy to install with a 150mm overlap of foil provided on one side of the roll for simple and quick joining with standard foil tapes.
