GOOT zero ODP Phenolic Pre-insulated air duct system is one of the most advanced and energy saving HVAC ductwork all over the world. The system consists of Phenolic pre-insulated panels and accessories. The panels consist of phenolic foam insulation faced on both sides with 75 micron thickness aluminium 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 labour and cost. 2. Save the building space 3. Very light, decrease the total weight of building 4. Little air leakage by flange joint connecting 5. Low thermal conductivity, no condensation and energy saving 6. Closed cell foam, good acoustic insulation 7. Fire proof, no smoke when exposing to fire 8. Faced with aluminium foil, its water proof and anti-microbial 9. CFC and HCFC free, environment friendly
