Headquartered in New Castle, Pennsylvania, we design, manufacture and sell air curtains, also known as air doors: when the door is open we have the energy saving doorway solution for comfort & safety. Amidst the rolling hills of Western PA, the Berner manufacturing plant combines state of the art equipment with highly skilled workers to produce the most efficient, cost-effective, and reliable air curtains on the market. Our strong commitment to listening to our customers and solving their problems has set Berner apart from the rest. In the late 1970s, Berner took the lead in approaching the other air curtain/air door manufacturers to work with A.M.C.A. (Air Movement Control Association) to successfully develop a certified method of rating air curtain performance. Product performance is critical, and at Berner, we believe our customers deserve the best assurance that our products perform as stated.
