TD Pre Insulated PIR Air Duct Panel is composed of a layer base from good fire retardant rigid polyisocyanurate foam, covering both sides with a 75 μm embossed aluminium foil and coupled with layers of corrosion resistant paint.
TD Pre Insulated PIR Air Duct Panel use "245FA" so-called free-freon foam agent. We understand the products with 245FA will gradually replace the one which using 141B the freon foam agent what damage to ozonosphere. Many countries around the world have taken free-freon environmental technology as the laws and regulations, and set up technical barriers to restrict imports. Our PIR panel will break the barriers, it will help a lot on our TD promotion in worldwide market. On the other hand, with the strengthening of people's awareness to environmental, more and more projects have chosen to use a green product. TD PIR Panel will meet the requirement of the market.

Excellent, constant thermal insulation thanks to the high density polyisocyanurate(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.
