A vestibule exception was the only exception we made while developing the EVE.
A low-profile, contemporary style outlines this high-performing air curtain designed to be used in vestibules, front doors, customer doors and other areas requiring a sleek, aesthetically pleasing air curtain. The Eve comes standard in a beautiful stainless steel case and can also be powder coated in a white or black finish. The EVE meets ASHRAE 90.1 and IECC requirements for vestibule exceptions and is available in both unheated and electrically-heated options.
