AD-375 Thermal Entrance


The AD-375 Thermal Door is a high performance thermal entrance product designed to meet or exceed today’s energy codes for entrances. The door is 2-5/8" thick utilizing a 20mm thermal strut. Optional foam inserts are available in the 1" glazed doors and are standard for 1-9/16" glazing to increase thermal performance. Only insulated glazing may be used in the AD-375 Thermal Door and, when used in combination with Low-E glazing products, can match the thermal performance of many of today’s thermal curtain walls. The AD-375 Thermal Door is available as a single door, pair of doors or in sets of singles separated by a 2" common lock mullion or 5-1/2" common hinge mullion utilizing a 1" x 4-1/2" deep sub-frame around perimeter of openings.
