Commercial ventilation brings outdoor air into a building and removes stale air, using fans and ductwork to supply and extract air at the rates needed for the number of people and the activity.

Before you book in Northwich
Noise
Fans and grilles are selected and attenuated to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Northwich are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Leased premises
If your Northwich premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
