Air doors help prevent cold or warm air, insects and contaminants from entering through a doorway. Also called an air curtain, an air door utilizes a controlled stream of air aimed across an opening to create an air seal. This seal separates different environments which allows for a faster flow of traffic and clear vision through the door opening. Air doors help contain heat and air-conditioning air which provides sizable energy savings and personal comfort. They also create a much cleaner and healthier environment.
