Flat Shutters

Flat ducting shutters stop backdraughts in low-profile plastic ducting runs — when the extractor fan or cooker hood switches off, the shutter closes and prevents cold outside air, draughts and smells travelling back down the duct into the room.

The shutter fits in-line within the flat channel run and operates automatically: airflow pushes it open when the fan runs, and it closes again the moment the fan stops. Available in 110mm × 54mm and 204mm × 60mm to suit our flat plastic ducting.

On round sections of the same system, use a circular back draught shutter (100–200mm) instead. Stocked items ordered by 3pm are dispatched for next-day delivery, and UK mainland delivery is free on orders over £400 ex VAT.
