The UNTDuct Polyisocyanurate (PIR) Foam Pre-insulated air duct panel is widely used for the air distribution of central air duct system, which is one of the most advanced and energy-saving air duct systems. The system is composed of CFC & HCFC free Polyurethane Foam Pre-insulated air duct panel and professional supporting accessories & tools. By taking the rigid insulation foam as the core material and covered with embossed/smooth Aluminum foil on both sides, PU Foam Pre-insulated air duct panel obtains excellent performances of low vapor permeability, thermal resistance and good toughness property, which is also environment Friendly.

Advantages of UNTDuct Polyurethane(PU) Pre-insulated HVAC Ductwork:

1. Lower heat conductivity, higher thermal efficiency

2. Low density, light weight

3. Foamed with CFC free materials, environment protective 

4. Hermetic seal ensures little air leakage

5. With aluminum foil reinforced on both sides, its corrosion protective, hygeian, and has a beautiful appearance. 

6. Foamed with closed-cell structure, its water-proof and sound-insulated.

7. Easy making, rapid installing and convenient maintenance saves cost.

8. No protrudent flange on the connections, it can save a lot of building space.
