The OptiQ® Offset Fixed/Projected Series Window is engineered to deliver classic style with ultra-thermal performance while supporting sustainable facade design. Featuring a single contiguous frame, the system incorporates a fixed lite on top with an offset operable vent or fixed lite underneath, offering the simplicity of a traditional single-hung aesthetic with enhanced performance and ease of use.

Designed for new-build and retrofit applications, the window meets stringent energy codes and ultra-thermal requirements. Its innovative construction achieves near triple-glaze performance with a double-glaze option, helping reduce energy consumption and improve overall building efficiency.

With U-factors as low as 0.35, the system supports high-performance building envelopes across healthcare, education, multifamily and commercial applications. The window also contributes to sustainability goals through supporting documentation, including a Product Green Guide and Environmental Product Declaration (EPD), and alignment with programs such as LEED, WELL and Living Building Challenge.

Aligned with Kawneer’s broader commitment to reducing environmental impact, the system supports lower embodied carbon through the use of recycled aluminum and energy-efficient design strategies that help reduce operational emissions over the building lifecycle. This is reinforced by Kawneer’s billet sourcing approach, which combines 50% recycled aluminum with 50% hydroelectric-powered primary aluminum, delivering full material transparency.
