TD Pre Insulated Aluminium Composite Air Condition Duct Panel is composed of a layer base from good fire retardant rigid PU(polyurethane) or PIR(polyisocyanurate) foam, covering both sides with a 75 μm embossed aluminium foil and coupled with layers of corrosion resistant paint. 

TD Pre Insulated Aluminium Composite Air Condition Duct Panel is approved by third party in Australia as per AS/NZS 1530.3-1999.the methods for fire tests on building materials, components and structures - Simultaneous determination of ignitability, flame propagation, heat release and smoke release. We are manufacturing based on it.
