Air Curtains in Bury St Edmunds

Air curtains are fitted directly above doorways and project a continuous blade of air downwards to seal the opening without restricting entry or exit. They are widely used in retail units along Bury St Edmunds town centre, food service premises, loading bays and any commercial space where doors are frequently open and temperature control matters. They also act as a barrier against flying insects, which makes them particularly useful for kitchens and food preparation areas.

Installation involves fixing the unit above the door opening - typically flush with the front face of the doorframe - and connecting it to a power supply. Larger units for industrial doorways require a hardwired three-phase connection; smaller commercial units commonly run on a standard single-phase supply. The throw distance and outlet velocity must be matched to the door height for the curtain to work properly. A unit that is too weak for the opening it covers provides little real benefit, so we always check door dimensions and usage before recommending a model. We can also connect the air curtain to a door contact switch so it runs only when the door is open, which reduces running costs.

A professionally fitted air curtain positioned and specified correctly can reduce heat loss through an open doorway by a substantial margin compared with leaving it unaddressed. For premises with high footfall and doors that are open for much of the trading day, the energy saving relative to the installation cost is often recovered within a few heating seasons.

The installation itself is typically completed within two to four hours for a single doorway. Multiple doorways or more complex wiring arrangements take longer, and we assess this during an initial visit.

Air curtains for standard commercial doorways in Bury St Edmunds are typically priced between £300 and £900 fully installed, depending on door width, unit specification and the electrical supply arrangement required.
