Traditional central air-conditioning air supply ducts are usually made of iron sheet or fiberglass as the inner layer, wrapped with insulation materials, and wrapped with aluminum foil on the outside, which makes the air supply duct heavy in weight, time-consuming in construction and installation, poor in appearance and low in air tightness , High energy consumption. The most advanced method is to use aluminum foil as the inner and outer layers, and rigid polyurethane foam board as the core material.

The central air-conditioning air duct made of polyurethane board not only has the advantages of heat preservation, sound insulation, and anti-bacterial growth, but also has the advantages of light weight, beautiful appearance, durability, and quick construction. Because the central air-conditioning air duct made of aluminum foil veneered rigid polyurethane board has the above-mentioned various advantages, it has been widely adopted by foreign central air-conditioning manufacturers.

Domestic manufacturers in Shanghai, Zhejiang, Shandong, Beijing and other places have produced this panel, and the air-conditioning ducts made of this panel have been used in some buildings. The central air-conditioning duct made of aluminum foil-faced polyurethane foam board can be applied to the central air-conditioning system of airports, food warehouses, clean factories, shopping centers, hotels, etc. The material area required for central air-conditioning air supply ducts is generally 20% to 25% of the building area, so its application prospects will be very broad.
