THERMAL The new AA™5450 Series Window – the latest in the OptiQ™ Ultra Thermal Window series – continues to set the standard for brilliance in window design.

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



BRAINS AND BEAUTY The AA™5450 Series Window combines intelligence and good looks to deliver inspired aesthetics.
The 4-5/8" (117.48 mm) frame depth provides high thermal performance, while its minimal sightlines provide a sleek appearance. A dual color option offers the flexibility to vary interior and exterior finishes, which enables designers to coordinate and accent multiple environments while also controlling costs.
This versatile window is available in several configurations, including fixed, single-hung, double-hung and sliding. Both hung and slide options make various ventilation configurations possible to meet a wide range of building conditions.
*A new beveled face design option for single hung and double hung configurations make the AA™5450 Series window an ideal solution for renovation or replication projects seeking a historic look.

THERMAL EFFICIENCY Thermal transmission is further reduced through the use of insulating foam strips and interior gaskets, as well as the ability to accommodate 1-1/2" triple glazing.
The AA™5450 Series Window provides outstanding condensation resistance – an important performance feature in applications such as hospitals and schools where condensation and mold are significant concerns.
Superior thermal efficiency also makes the window ideal for buildings seeking Leadership in Energy and Environmental Design (LEED®*) certification.
