Polyurethane (PU) Duct Board With Aluminium Foil

 

Polyurethane (PU) Foam Duct Board

with Aluminium Foil is an integrated, high-performance solution for HVAC air distribution systems, designed to combine insulation, protection, and airtightness in one structure.

Core Structure & Key Specifications

It adopts a sandwich design:

Inner Core: Dense closed-cell polyurethane (PU) foam, typically 10–40mm thick. The foam has a density of 45–55 kg/m³ and ultra-low thermal conductivity (0.020–0.022 W/m·K), the core for thermal insulation.

Outer Layers: High-quality aluminium foil (0.06–0.08mm thick) bonded to both sides of the PU core. The foil can be plain, embossed, or colored (e.g., white) for different aesthetic and functional needs.

Its working temperature range is -100℃ to +80℃ (continuous operation ≤70℃), and it meets airtightness standards with leakage rates <2%-far lower than traditional metal ducts.

1.Low thermal conductivity (0.022w/m.k) makes it the most thermally efficient, and hence the thinnest insulation product commonly used for pre-insulated HVAC ductwork.

2.Low ductwork air–leakage can yield significant electrical consumption savings because of reduced heating and cooling loads, and fan energy usage.

3.Weighs up to 72% less than ductwork constructed from GI makes it ideal for refurbishment projects, where existing building structures have insufficient load capacities for new service loads.

4.With anti-bacterial aluminum foil reinforced on both sides, its corrosion protective, hygeian, and could be visibly mounted.

5.Low weight ductwork fabricated in sections and single–fix installation and no need to install insulation as a second operation, reduces project scheduling periods for insulated ductwork.

6. Ductwork fabricated from UNTDuct System is rigid, strong and self–supporting and has a life of more than 20 years.
