Do air curtains keep heat in?

Do air curtains keep heat in? Yes, one of the main purposes of an air curtain is to help keep heat inside a building. It does this job by producing a controlled stream of air across the doorway, reducing the amount of warm indoor air escaping and cold outdoor air entering.

They also work in the reverse manner for air-conditioned locations, in that they can prevent cold air from escaping to the outside.

Air curtains are particularly effective in locations where doors open frequently, such as shops, warehouses, offices, restaurants, and loading bays. Air curtains reduce infiltration or transfer of air when applied across the full height and width of an opening.

An air curtain will not stop all heat loss, but it can significantly reduce uncontrolled air movement. For best results, it should cover the full door width, be mounted at the correct height, and be set up with suitable fan speed and controls.
