THERMAL The new GLASSvent UT Windows are the ideal solution for architects and designers who want to provide fresh-air ventilation without sacrificing thermal performance in curtain wall or storefront applications.
GLASSvent UT Windows are engineered to meet or exceed the minimum requirements for the architectural window performance class, including life-cycle testing – the highest level attainable.
GLASSvent UT Windows have been rigorously tested to both AAMA and CSA standards for air, water, structural, thermal and condensation performance.

THERMAL SIMULATIONS Thermal simulations show temperature variations from exterior/cold side to interior/warm side of GLASSvent UT Windows.



BRAINS AND BEAUTY Engineered for seamless integration with the 1600UT System1 Curtain Wall, GLASSvent UT Windows can also be inserted into other Kawneer captured curtain walls and front set framing systems.

FLEXIBILITY The new GLASSvent UT Windows are the ideal solution to provide fresh-air ventilation without sacrificing thermal performance in curtain wall or storefront applications.
GLASSvent UT Windows are available with the option to buy the window factory glazed by Kawneer or open for glazing by the window installer.
The flexibility of GLASSvent UT Windows gives architects an ultra thermal option that combines high-performance vents with high-performance curtain walls and storefront systems, including the 1600UT System1 Curtain Wall.
