Model 35XT, Model 50XT
SYSTEM DESCRIPTION: Architects seeking LEED certification can enhance a project's energy conservation by specifying YKK AP's new high-performance MegaTherm® XT thermal entrances. To save energy, all aspects of the doors, including the frames and thresholds, are thermally broken by YKK AP's MegaTherm polymer, which separates the interior and exterior extrusions by more then .270 inches to reduce energy flow. Thermal entrances feature foam polymer inserts and dual perimeter air seals for superior performances over standard entrances. For example, a Model 35XT pair, when using insulating glass with a soft coat, low emissivity coating, and aluminum spacer - has a U-Factor of 0.49. Thermal entrances are available in medium stile, Model 35XT, and wide stile, Model 50XT, configurations. A wide selection of hardware options for hinges, locks, closers, mid-rails, and bottom rails are available. Framing solutions integrate into most YKK AP systems utilizing MegaTherm or ThermaBond Plus® thermal breaks. MegaTherm entrances accept 1" insulating glazing units. Door corners are mechanically joined/welded and carry a lifetime warranty.   Standard Entrances : Singles: 3'-0" x 7'-0" Pairs: 6'-0" x 7'-0" Offset Pivot, Butt Hung and Continuous Hinge MS Lock, RIM and CVR Exit Device Custom Entrances : Singles: 4'-0" x 8'-0" Pairs: 8'-0" x 8'-0" Standard and Custom Hardware
