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

TD Pre Insulated Aluminium Composite PU (Polyurethane) Air 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.

Advantage
Fire safety, fire retardant B1
Excellent, constant thermal insulation thanks to the high density polyurethane(52+/-2kg/m3)
Light wieght, TD ducts weight 1.46kg/m2 compared to 9.8kg/m2 sheet metal duct.
Silent operation, vibration and reverberation are minimized, increasing system comfort.
Hygienic and does not absorb humidity.
Air tight seal, very low are leakage, the leakage test result is only 0.98m3/h.m2.
Simple and easy but highly productive fabrication and installation
Easy maintenance and modification can be performed on site, cut and gluing can be applied in any section of the ducts.
Excellent appearance and long lasting, life expectancy are 20 years.
