Flexible Duct (Pre-Insulated)


Flexible Duct (Pre-Insulated)
Product Name: Insulated Flexible Duct
Availability: In Stock

Pre-Insulated Aluminium Flexible Duct comprises two concentric Helical Ducts that house the fiberglass wool between them, making it strong and sturdy with excellent strength and flexibility. It is specially designed and used in air-conditioning and ventilation systems for commercial, industrial and residential applications.

Pre-Insulated Aluminium Flexible Duct range has been developed to minimize the heat gain or loss resulting from the temperature difference between the air flowing in a duct and the surrounding air. The vapor barrier prevents condensation forming on the outside of ducts carrying air at lower temperatures than the surrounding air.
