PU Air Conditioning Ductwork

PU Air Conditioning Ductwork, also referred to as PU aluminum foil duct board or PU sandwich air duct panel, is a high-performance composite material specially engineered for HVAC heating, ventilation and air conditioning ductwork systems.

The panel features a three-layer bonded composite structure:

Two outer faces: Heavy-duty aluminum foil, available in smooth or embossed finishes

Central core: Rigid polyurethane (PU) foam, serving simultaneously as structural reinforcement and thermal insulation.

Structure: Silver Aluminum/ PU Foam/ Silver Aluminum
Size: 3950*1200*20mm
Foam Density: 50kg/m3
Aluminum Thickness: 0.06mm or 0.08mm
Aluminum Color: Silver
Packing: 10 sheets/ package
Loading Capacity: 710 sheets/ 40'HQ (packed with plastic bags)
660 sheets/ 40'HQ (packed with cardboard box)

Economic efficiency throughout the entire life cycle of PU Air Conditioning Ductwork

By using the third-generation modified MDI raw material, the service life of the board is extended to over 30 years, which is 2 to 3 times that of ordinary insulation materials. Meanwhile, its recyclability has broken through the industry bottleneck - after being crushed and reshaped, the waste boards can still maintain over 85% of their original performance.

Take industrial plants as an example. The comprehensive cost throughout their entire life cycle can be reduced by 28% compared to traditional insulation solutions.

Integrated structural and thermal insulation solution of UNT PU Air Conditioning Ductwork

Breaking through the single positioning of "only used as an insulation layer", the board itself has a compressive strength of over 2.5MPa and can be directly used as a lightweight load-bearing structure.

In the construction of cold chain logistics vehicles, there is no need for additional steel structure supports. Just by joining the panels, both insulation (with a temperature difference maintenance capacity of up to 48 hours) and structural load-bearing (capable of bearing 300kg per square meter) requirements can be met simultaneously, shortening the overall construction period by 40%.
