First of all, Aluminum foil ventilation duct has excellent thermal insulation performance. It is environmentally friendly and energy-saving, and can effectively perform the thermal insulation function and prevent the surface of the air duct from being exposed. Secondly, it has excellent air-tightness, high air supply quality, and is clean and hygienic. The aluminum foil with smooth surface and extremely low air leakage not only ensure the hygiene of the conveyed air medium, but also avoid secondary pollution. Finally, it's lightweight and looks great. Aluminum foil ventilation duty is 10% of the weight of iron air ducts, which greatly reduces the load-bearing requirements for brackets, hangers, etc., which can effectively reduce the building load.Considering the four-season materials, its applicable temperature is-20ºC to +100ºC.
