Phenolic / Polyurethane Foam Pre-insulated air duct system consists of Duct panels and accessories. The panels consist of Phenolic / Polyurethane foam insulation faced on both sides with 75 micron thickness aluminum foil. They are fabricated into ductwork by a set of tools supplied by us.Advantages compared to traditional insulated Sheet Metal Ductwork:1. Do it in one time, no lag insulation required, save the labor and cost.2.Save the buiding space3.Very light, decrease the total weight of building4. Little air leakage by flange joint connectting5.Low thermal conductivity, no condensation and energy saving6.Closed cell foam, good acoustic insulation7. Fire proof, no smoke when exposing to fire8. Faced with aluminum foil, its water proof and anti-microbial9.CFC and HCFC free, environment friendlySpecification and Technical DataSize: 3900*1200*20mmFoam Density: 50-55kg/m3Thickness of Aluminum Foil: 75micronThermal Conductivity(at 10°C Mean Temp): JIS A1412(1994) 0.02W/m.KFire Test Classifications: BS 476 Class 0 ASTM E-84Class A UL94-199894V-0Closed Cell Content: >90%Water Vapor Transmission: ASTM E96-05 0.05g/hr/Sq m (at 23, 50% R.

While retaining the advantage of normal type pre-insulated air duct, this reinforced type is much more strong and endurable.
