Aluminium Faced PU Air Duct Board

Aluminum Faced PU Air Duct Board is a pre-insulated panel system designed as a modern, high-performance alternative to traditional metal ductwork for HVAC applications.

What It Is?

This board is a composite sandwich panel featuring a rigid closed-cell polyurethane (PU) foam core permanently bonded between two layers of aluminum foil. It is designed as an all-in-one solution that serves as both the air channel and the thermal insulation, eliminating the need for separate external insulation commonly required with metal ducts.

Advantages of Aluminium Faced PU Air Duct Board

The Aluminium Faced PU Air Duct board's structure provides several key benefits over traditional metal ducts:

Superior Thermal Efficiency:

The PU foam core has a very low thermal conductivity (around 0.020 W/(m·K)), which minimizes energy loss from conditioned air and can cut HVAC energy consumption by an estimated 15-25%.

Lightweight and Fast Installation:

The board is about 70% lighter than galvanized iron ducts, making it easier to handle and transport. The integrated design allows for installation to be up to 40% faster, as it requires no additional on-site insulation.

Excellent Airtightness:

When properly sealed, the system can be up to eight times more airtight than traditional metal ducts, significantly reducing air leakage and further improving efficiency.

Hygienic and Durable:

The smooth aluminum inner surface resists corrosion, dust, and bacterial growth, making it suitable for hygiene-sensitive environments like hospitals and food processing facilities. The closed-cell foam is also highly moisture-resistant, preventing mold and condensation.

Acoustic and Fire Performance:

The foam core acts as a sound barrier, dampening airflow noise. The panels are also manufactured with fire-retardant materials and comply with stringent international fire safety standards.
