- Plan an extra protective coating against UV and rain for outdoor ducts.
- Order adhesive, aluminium tape, flanges and corner profiles with the boards.
- Send the duct take-off and we will work out the number of boards including waste.

Description
Pre-insulated duct boards replace galvanised ducts plus separate insulation with a single material, giving light, condensation-free and quick-to-install ductwork for offices, malls, hotels, hospitals, clean rooms and food plants.
For outdoor and rooftop runs, boards with a thicker outer aluminium facing are recommended. We supply them with jointing profiles, adhesives and accessories, with alternative quality options to suit your requirements.
