TD Pre-Insulated Aluminium Ducts is developed specially for the air distribution fields and the answer to economical, technical, and constructive question.

Many different material and system such as composite, PVC, etc had been developed as an alternative to the galvanized sheet metal used traditionally.

TD Insulated Aluminium Ducts is the best solution. It is a sandwich panel composed of a layer base from good fire retardant rigid polyisocyanurate foam covering both sides with aluminium foil, the aluminium guarantees sturdiness and withstand corrosion in long term use.

Polyisocyanurate, also referred to as PIR, is essentially an improvement to polyurethane(PUR). PIR foam is more difficult to break, chemically & thermally more stable than PUR.

Polyisocyanurate pre-Insulated duct has been developed and spread around the world especially European countries & middle east country, its application has been gradually extended to all types of air distribution system such as industrial, commercial and civil.

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.
