Product Description:



The  Phenolic Foam Preinsulated Duct panel system is the most advanced and inovative energy saving system of centre air-conditioning ductwork available worldwide. The Ductwork is fabricated by using rigid phenolic insulation panels in length of 4m and  provide the optimum energy saving and environmental solution in comparison with other types of ductwork. The system consists of Phenolic Pre-insulated Duct Panels, fabrication methods, jointing systems and a complete line of accessories to complete a system.

The Phenolic Foam Preinsulated Duct System is the recoganized leader in new generation pre-insulated ductwork. It offers the triple benefits to cut down the energy, carbon and cost whilst already having proved itself in its highly competitive marketplace. Being based on a phenolic resin it has outstanding fire resistance characteristics and extremely low smoke emission when expose to a flame source.
