These operable Tubelite UniVent 1375AW Series Therml=Block Windows are engineered to complement and seamlessly integrate within mid- to high-rise commercial buildings’ storefront and curtainwall systems. The windows offer natural ventilation and increased fresh air exchange. As part of a sustainable, passive house design strategy, operable vents can lower HVAC loads, reducing associated utility costs.

These aluminum-framed windows are thermally broken and insulated with polyamide strut, further contributing to high-performance, energy-efficient building envelopes. The aluminum framing is available in high-performance standard anodized or painted finishes. Specialty finishes, custom colors and dual finishes also may be specified.
