PUR Foam Duct Panel

Integrated sandwich structure: Inner and outer aluminum foil + high-density PU rigid foam, formed in one step, without thermal bridges, low air leakage rate, stable structure and less prone to deformation.
Outstanding insulation and energy saving: Thermal conductivity ≤ 0.022W/(m・K), closed-cell ratio ≥ 95%, under the same thickness, the insulation efficiency is superior to conventional materials, and can reduce air conditioning energy consumption by 20%–30%.
Lightweight and high strength: Density 40–55kg/m³, 60% lighter than traditional galvanized steel ducts, reducing building load, enhancing seismic and impact resistance.
Fireproof, moisture-proof, and mold-proof: B1 grade flame retardant, high oxygen index, non-absorbent, no mold growth, suitable for clean and humid environments.
Sound insulation and vibration reduction: Foam core buffer noise reduction, reducing wind noise and equipment vibration, improving indoor comfort.

High-end commercial buildings: office buildings, shopping malls, hotels, focusing on energy efficiency and installation efficiency.

Clean environments: hospitals, pharmaceutical factories, electronic workshops, food factories, meeting cleanliness, mold prevention, and aseptic requirements.

Data centers / computer rooms: strict temperature control, large air volume, requiring low resistance, low leakage, and high-stability ducts.

Rail transit / factories / cold storages: heavy load, corrosion resistance, long lifespan, and prominent energy-saving requirements.

Market Trends: Under the dual-carbon and green building policies, it is rapidly replacing traditional iron sheet ducts and the domestic and international demand is continuously increasing.
