Kawneer AA 250/425 Thermal Entrance doorframe jambs and transom bar/door headers have a dual perimeter seal featuring Kawneer’s Sealair bulb weathering. The entrance provides triple-finned, soft pile weather stripping that minimizes airflow around the door’s perimeter edge. The combination of a thermally blocked threshold and dual bottom door sweeps minimizes air infiltration into the building. The door is 2.25-inches deep and has a 1/8-inch typical wall thickness. It includes offset pivots, butt hinges or geared hinges and offers surface-mounted or concealed closures. The product also features a 1-inch insulated glass infill and a dual-welded corner construction. The painted finished includes standard and custom choices.
