Kawneer introduces two new doors

Kawneer Co. Inc. has introduced its AA250 and AA425 Thermal Entrance Doors. In conjunction with Kawneer's high-performing frame, the doors offer improved thermal efficiency compared to a standard door.

By combining critical elements within the product design, the AA250 and AA425 Thermal Entrance Doors create a superior thermal roadblock. The thermal roadblock formula includes thermal breaks in the door, door frame and threshold that isolate the interior metal components from the exterior metal components. A door rail and stile design with a double air cavity provide an added layer to the thermal barrier and dual weathering around the perimeter of the door in conjunction with a low conductance polymer door stop minimizes air infiltration.

For improved comfort and savings in heating and cooling costs, Kawneer has incorporated several innovative features into the entrances. In addition to thermal breaks, Kawneer has added its proven corner construction, which has four Sigma deep penetration and fillet welds plus mechanical fastening at each corner. The immediate door frame jambs and transom bar/door tout a dual perimeter weather seal featuring Kawneer's Sealair bulb weathering. Also featured is a triple-finned, soft pile weather stripping that minimizes airflow around the perimeter edge of the door. The combination of a thermally broken threshold and dual bottom door sweeps minimizes air infiltration at the bottom of the door. The AA250 and AA425 Thermal Entrance Doors accommodate 1-inch insulating glass and insulating laminated glass to improve thermal and sound reduction performance. Laminated glass enhances STC and OITC (sound resistance) performance as well as improving occupant safety. Kawneer's thermal entrance doors have been tested in accordance with applicable North American performance standards for air, structural, condensation, thermal and sound transmission.

AA250 and AA425 Thermal Entrance Doors break from tradition to deliver a new aesthetic look with a 2 1/2-inch narrow stile and 4 1/4-inch wide stile respectively. To meet aesthetic and hardware application requirements, the entrances are also offered with a range of top and bottom rails. Horizontal mid-rails are available in 1 3/8-inch and 8 1/4-inch sizes. Additionally, Kawneer offers a 10-inch bottom rail option. The 2 1/4-inch door uses a 14mm polyamide strut thermal break that accommodates a dual finish as well as various combinations of hinging and locking hardware, which include: offset pivots; butt hinges; continuous gear hinges; MS locking; concealed vertical rod exit devices; and rim exit devices. Available finishes for the AA250 and AA425 Thermal Entrance Doors include Kawneer's range of anodized and painted finishes, including fluoropolymer and environmentally-responsible solvent-free powder coatings, in a variety of color choices.
