  保温性能 镀锌薄钢板风管:导热系数很大(为60.4 W/m·K) ,无保温性能,必须另外加包保温层及保护层。

  Thermal insulation performance of galvanized thin steel pipe: thermal conductivity is large (60.4 W/m / K), no thermal insulation performance, must add additional insulation layer and protective layer.

  In the air duct processing department, the insulation thickness is not easy to guarantee or no heat preservation, the cold bridge phenomenon will occur, and the uniformity of the insulation layer of the wall of the air duct will sometimes be difficult to guarantee because of insufficient installation clearance. Inorganic glass fiber reinforced plastic air duct: large thermal conductivity (0.5W/m = K), no thermal insulation performance, must add additional insulation layer and protective layer, insulation layer characteristics with galvanized thin steel pipe duct.
