Polyurethane Composite Ductwork

Commonly named PU aluminum foil duct board or PU sandwich duct panel, the Polyurethane Composite Ductwork is a premium composite material widely applied to HVAC ventilation and air conditioning duct systems.

Its integrated three-layer bonded construction includes:

Double outer layers: Durable aluminum foil with embossed or flat surface options

Middle core layer: Solid rigid PU foam that provides structural rigidity alongside excellent heat insulation performance

Structure: Silver Aluminum/ PU Foam/ Silver Aluminum
Size: 3950*1200*20mm
Foam Density: 40-45kg/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)

Performance/Service Life/Cost Performance of PU Composite Duct Panels

The thickness, width and length of the product can be customized. The surface can be processed with various techniques such as smooth finish, matte finish, or textured finish. The sheet material is easy to cut, slice, punch holes, and bond. The processing difficulty is low, and it can be formed on-site without the need for complex equipment. The PU Composite Duct Panels are lightweight, lighter than metal sheets, and makes handling and installation easier, reducing construction and transportation costs.

PU Composite Duct Panels are resistant to aging, insect damage and rotting. Under normal conditions, its service life can reach over 20 years, which is much longer than that of ordinary rubber and wooden boards. The initial purchase cost is moderate, and there is no need for frequent replacement and maintenance in the future. It is wear-resistant and durable, reducing the loss of accessories, and has an extremely high overall cost performance. It is a universal high-performance board suitable for industrial, construction and home decoration fields.

Integrated structural and thermal insulation solution of PU Composite Duct Panels

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%.
