YOW 350 XT
Thermally Broken Operable Window System for Insulating Glass

Best in Class Thermal Performance

YOW 350 XT achieves state of the art energy performance while utilizing standard 1" insulating glass. Innovative design attributes minimize energy loss through a multitude of thermal barriers. This factory glazed window wall system has an overall depth of 3-1/2" and is thermally broken by a combination of MegaTherm® Thermal Breaks and gasketing to insulate multiple air chambers. Improved occupant comfort is achieved by interior surfaces that are significantly warmer than traditional window systems in cold climates.
