Reducing Heat Loss and Infiltration with Air Curtains

For busy retail and commercial establishments, the simple fact of people coming and going can get expensive by the loss of conditioned or heated indoor air. Every time the door opens you are bringing in undesirable outside air, bugs, dust, pollen, etc. One solution for this problem is an air curtains at each doorway. These air curtains are mounted above the primary entrance/egress doors. Each time the door opens this air curtain turns on and blows a blast of air on the inside of the door locally pressuring this area. This slight pressurization and turbulence helps prevent the loss of expensive treated indoor air or the infiltration of outdoor conditions. It also helps to maintain indoor air quality.

Air curtains are inexpensive, easy to install and offer quick payback.
