PU Pre-insulated Aluminium Duct Panel

PU Pre-insulated Aluminium Duct Panel is a high-performance composite panel for HVAC duct systems, featuring a rigid PU foam core laminated with embossed aluminium foil on both sides. It delivers ultra-low thermal conductivity, excellent airtightness and anti-condensation performance. Lightweight yet structurally stable, it allows one-step fabrication without extra insulation, cutting installation time by 40–60%. Widely used in commercial, industrial and cleanroom projects, it reduces energy loss by 25–30% and offers long-term durability with corrosion resistance.

Performance Technology of PU Pre-insulated Aluminium Duct Panel

Structural mechanics: The PU core provides sufficient rigidity, and the aluminum foil reinforced panel surface strength enhances the strength. No additional reinforcement is required for the conventional wind pressure, and the panels are flat and less prone to deformation.

Moisture and condensation prevention: The water absorption rate is nearly zero. The aluminum foil blocks water vapor, and in high-humidity environments, there is no condensation or mold growth, extending the lifespan of the ducts.

Fire safety: The flame-retardant PU has a carbonized burning surface, without molten droplets, low smoke and toxicity, meeting building fire safety standards, and enhancing system safety.

Air tightness and air resistance: The panel surface is smooth, and the connection sealing is reliable. The air leakage rate is much lower than that of traditional ducts, with less air flow loss, and lower energy consumption for the fan.

Engineering Application of PU Pre-insulated Aluminium Duct Panel

Construction Efficiency: Prefabrication in the factory, on-site cutting and assembly, one-step process, no need for insulation wrapping, significantly shortens the construction period and reduces labor costs.

Load Advantage: The self-weight is much lighter than galvanized iron sheet ducts, reducing the building's load-bearing capacity, suitable for renovation projects, large-span and lightweight buildings.

Space Adaptability: The plates are thin and lightweight, which can be flexibly arranged in narrow spaces such as ceilings and pipe shafts, improving space utilization.

Maintenance Cost: Aluminum foil is corrosion-resistant and does not rust easily, has no risk of insulation layer detachment, and significantly reduces the workload for later maintenance.
