Phenolic Foam Duct Board Composite with Galvanized

Phenolic Foam Duct Board Composite with Galvanized Iron and Aluminium Foil (Phenolic foam GI air duct) is our newly-developed products used to make air ducts in central air-conditioning system. It takes phenolic foam as the core material and reinforced with Galvanized Iron one side and Aluminium Foil the other side. It has many advantages comparing with the traditional air ducts: High compressive strength, Uniform in apperance Do it in one time, no lag insulation required, save the labor and cost. Save the buiding space Very light, decrease the total weight of building Little air leakage by flange joint connectting Low thermal conductivity, no condensation and energy saving Closed cell foam, good acoustic insulation Fire proof, no smoke when exposing to fire CFC and HCFC free, environment friendly
