The slider configuration provides quick ventilation without the exterior projection of an awning window, making it well-suited for high-traffic locations, tight wall spaces, or clearance-sensitive installations. They feature the same 70mm corner radius as our awning-style windows for consistent installation and aesthetics. Now available by custom order in glass or acrylic options to match your build’s needs.
A fresh window style from a trusted brand, combining a square-frame, double-pane flat acrylic design, cam-lock struts, a darker tint and a new low-profile shade and screen system. The result is modern styling, and the innovation you expect. Available in 2026, contact our team for pre-order information and availability timelines.
