Prefabricated Air Duct Board

Specifications

Phenolic foam aluminum foil composite air duct panel is light in weight, cost effective, reinforced with aluminum both sides.

We have been specialized in the manufacture of air duct panel since our establishment in 2002. Our air duct systems consist of phenolic foam as a core material which is sandwiched between a high strength, reinforced aluminum foil or colored steel. Huahai air duct systems consist of our patented, noncombustible material which gives off no smoke or poisonous gas when exposed to fire. It's bending strength reaches over 1Mpa and the thermal conductivity index is 0.020w/mk. The phenolic foam can be fabricated into all kinds of rectangular (bended) ducts by cutting and connecting using adhesives. It can then be assembled into the air ducts of different specifications by using the patented fire-resistant flanges and adhesive. Huahai air Duct Panels are widely used for the ventilation systems of central air conditioning units in hotels, apartments, hospitals, office buildings and other buildings.
