Product Description
●Have all the advantages of single-sided color steel composite phenolic foam insulation air duct board;
●Long service life, up to 30 years, good cost performance;
●High-strength structure can not be easily damaged in complex construction;
●The fire resistance time is up to 120 minutes;
●Small friction along the layer, no dust during use, easier to clean;
●It can be applied to engineering requirements with wind pressure above 2000Pa.
●Suitable for high clean environment;
●Sound-proof and good thermal insulation performance
●Effect: Significantly reduce noise caused by draught fan; Improve thermal insulation performance
