Polyduct Duct Work System
Advantages
- Quiet operation - Noticeable decrease in the audibility of crosstalk and equipment noise.
- Better temperature control.
- Lightweight and excellent workability result in speedy installation and cost saving.
- Anti microbial agent in the resin provides resistance to fungi and microbial growth eventhough dust or dirt is accumulated on the airstream surface.
- Energy conservation.
- Withstand high air velocity and static pressure without fiber erosion.
- Low water absorption.
Uses
As a replacement for the conventional ductwrap system, the ductwork system fabricated from Polyduct Duct Work System is ideal for heating or air-conditioning in commercial buildings, hypermarkets, factories, and office.

Fabrication Method

There are basic ways to fabricate straight fibre glass duct sections. The best way depends on the duct size, total stretch-out, labor and material optimization, and availability of "drop-off' duct board left over after large, one-piece or two-piece ducts have been fabricated. |
