The S70SK Zero Sightline Vent is a 2¾″ operable vent system engineered to maintain pristine aesthetics in contemporary façades. Designed for seamless integration with stick or unitized curtain wall systems, this near-invisible vent solution preserves uninterrupted glass surfaces while delivering essential ventilation and building comfort.
Why “Zero Sightline” Matters
Zero sightline vents create a glass façade that appears fixed—even when operable—by minimizing visible frame borders and using concealed fixation methods. This ensures that the visual continuity of high-performance glass walls remains intact, which is highly valued in modern architectural design.
