Color Steel Laminated Phenolic Foam Air Duct Pre-insulated HVAC Ductwork
W.T Aluminium Foil Laminated Phenolic Foam Insulation Board is a new type of hight-tech composite insulation material. This product is composited by embossed aluminum foil and phenolic foam by special onetime continuous production line, with a sandwich structure. Two sides Non-woven fabric are special treatment, to ensure good bonding between layers. Phenolic foam insulation layer adopts advanced foaming technology with fine bubble and uniform density, strength and thermal insulation properties are guaranteed.
