The ventilation phenolic board is usually composed of phenolic foam in the middle layer and embossed aluminum foil in the inner and outer layers. There are also single-sided color steel phenolic duct panels, double-sided color steel phenolic duct panels, and special flanges and other accessories that can be made into phenolic composite ducts for central air conditioning ventilation. In terms of bending resistance, compression resistance, and processing performance, it is very good and basically meets the requirements for the use of air conditioning ventilation pipes.
Advantages of ventilated phenolic panels:
Good insulation, which can greatly reduce the heat dissipation loss of air conditioning
The thermal conductivity of ventilated phenolic panels is 0.020~0.025W/(m · k), while the thermal conductivity of galvanized steel plates and fiberglass ducts is much higher. In addition, the unique connection method of the ventilation phenolic board ensures excellent airtightness of the ventilation system, which is close to 8 times that of galvanized steel plate ducts. Some data show that when conveying the same heat (cold) amount, the heat loss of galvanized steel duct is 15%, that of glass fiber reinforced plastic duct is 8%, and that of phenolic foam insulation material duct is less than 2%.
Lightweight, can reduce building load, and easy to install
The phenolic aluminum foil composite air duct is lightweight, which can greatly reduce the load on buildings and is extremely beneficial for the installation of air ducts. During installation, only one bracket needs to be installed every 4 meters to provide sufficient support. The bearing capacity requirements for brackets, suspension components, etc. are greatly reduced, making transportation and installation very convenient.
The service life of Foil Faced Phenolic Duct Insulation Board shall be at least 20 years. Therefore, the service life of phenolic aluminum foil composite air ducts is more than three times that of traditional air ducts. In addition, the reuse rate of phenolic aluminum foil composite air ducts can reach 60%~80%, while traditional air ducts can hardly be reused.
Our company supports OEM and ODM, and the Phenolic Ductwork size and thickness can be customized.
