The phenolic duct system is designed for high-risk environments. It uses closed-cell foaming technology to achieve ultra-low thermal conductivity (0.022W/m·K), which is 80% lighter than traditional metal ducts and meets Class A fire protection standards. The smooth inner wall design reduces wind resistance and is suitable for commercial buildings, laboratories and industrial exhaust systems.
