PU Aluminum Duct Sheet (also known as PU aluminum foil duct panel or PU sandwich duct panel) is a high-performance composite material used primarily in HVAC (Heating, Ventilation, and Air Conditioning) air duct systems. 

It consists of three bonded layers:Two Outer Layers: High-strength aluminum foil (typically embossed or plain).Core Layer: Rigid polyurethane (PU) foam, which acts as both a structural support and thermal insulator.

 

Structure: Silver Aluminum/ PU Foam/ Silver Aluminum
Size: 4000*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)

Lightweight: 

Typically 1/4 to 1/3 the weight of traditional galvanized steel ducts, reducing building load and installation labor.

Excellent Thermal Insulation: 

The PU foam core has a low thermal conductivity (around 0.02–0.025 W/m·K), minimizing heat loss/gain and eliminating the need for separate external insulation.

Air Tight & Leakage Resistant: 

Properly sealed joints (using aluminum tape or flanges) achieve very low air leakage, improving energy efficiency.

Corrosion & Moisture Resistant: 

Aluminum faces resist rust, chemicals, and humidity, making it suitable for coastal or industrial environments.

Smooth Inner Surface: Low friction loss reduces pressure drop, saving fan energy.

Built-in Vapor Barrier: No additional vapor retarder needed.

Easy Fabrication: Can be cut, grooved, and folded using hand tools, allowing quick on-site assembly.

PU Aluminum Duct Sheet offers a modern, energy-efficient, and labor-saving alternative to traditional metal ducts, particularly for medium- and low-pressure HVAC systems. Its integrated insulation, lightweight nature, and corrosion resistance make it increasingly popular in green building and energy retrofit projects.
