We recently introduced the AA™6400/6500 Thermal Window. Designed to keep the outside out, this new window delivers superior thermal and water performance and excellent condensation resistance. A fusion of beauty, strength and functionality, the AA™6400/6500 Thermal Window enhances any application – new and retrofit construction – while delivering architectural aesthetic appeal and ease of installation.

Superb Performance

The high-performing 4" (101.6 mm) deep AA™6400 Thermal Window and 5" (127 mm) deep AA™6500 Thermal Window achieve a superb condensation index (I-value). The advanced design provides the ability to interface with air and vapor barriers to ensure the continuity of the seal at the window perimeter.

Additionally, the AA™6400/6500 Thermal Window has a pressure-equalized cavity and a rain screen design that deters water infiltration.

Since the windows are made from aluminum, they will never rot, warp or buckle due to moisture and weather exposure. Because they attain outstanding condensation resistance, the windows are ideal for healthcare and education applications where condensation and mold are significant concerns.

Ease of Installation + Beautiful Aesthetics

The AA™6400/6500 Thermal Window is ideal for punched and strip openings. A specially designed coupling mullion allows the windows to be installed in a multi-modular strip application. Both framing systems can accommodate projected and casement vents, which can also be installed into our 1600UT (Ultra Thermal) Curtain Wall System™. The windows are interior glazed using a dry glazed method that allows for easy glazing and reglazing in the field – an added benefit in cold climates.

The operable vents have 45° mitered corners, which give the window a smooth and attractive appearance. A dual color option offers the flexibility to vary interior and exterior finishes, enabling designers to coordinate and accent multiple environments. Stylish hardware options include Euro-groove multipoint locking, roto operators and stainless steel 4-bar hinges or concealed hinges.
