PUR foam Aluminium Foil Duct Boards

With high-performance PU foam serving as its core substrate, PUR foam Aluminium Foil Duct Boards are lightweight composite components. Uniting thermal insulation performance, mechanical stability and certified fire protection in a single integrated structure, they enjoy extensive use across HVAC construction projects.

Adopting a modular all-in-one design, this duct solution lowers system energy waste, shortens on-site assembly time, and maintains reliable ventilation efficiency over prolonged operation.

Core Performance of PUR foam Aluminium Foil Duct Boards

Cleanliness and antibacterial: The inner self-cleaning coating imitates the principle of lotus leaves, making it difficult for contaminants to adhere. Combined with the antibacterial coating, it achieves an antibacterial rate of over 99%, solving the pain point of dust accumulation and bacterial growth in traditional air ducts.

Thermal insulation and energy conservation: With a thermal conductivity as low as 0.02W/m · K, its thermal insulation performance far exceeds that of traditional metal air ducts, reducing heat loss and condensation in air conditioning systems.

Durability: It features strong anti-corrosion, low-temperature resistance and vibration resistance. It remains flexible at -40℃ and has a service life of over 20 years in corrosive environments such as chemical and Marine industries, which is 3 to 4 times that of traditional air ducts.

Easy installation: It weighs only 1/3 of traditional iron sheet air ducts. No large lifting equipment is required. It can be moved and installed manually. It is flexible in cutting and splicing, and can adapt to complex ceiling layouts and narrow Spaces, shortening the construction period.
