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.
