Fireproof 20 Rigid HVAC Duct Aluminum Foil Stretchable Easy Installation

Product Description

Insulation Aluminum Foil Flexible duct is suitable for ventilation system of high, medium & low pressure central air-conditioning and others. It has high-performance of temperature resistance and fire-proof. The outer structure is consisted of two-layer of PET (high temperature resistance). One layer of them is electroplated with aluminum powder by high voltage static and glass fiber filament is in the middle of two-layer to consist outer structure complexly. Inner tube is made of aluminum-foil paper which is consisted of high quality aluminum alloy and PET (high temperature resistance), it is supported by steel wire of high tension spiral carbon steel.
