Why choose this 47.5" x 47.5" XO white vinyl Low-E window from The Window Depot?
The XO configuration allows the left panel to slide open while the right panel remains fixed when viewed from the exterior, offering smooth, space-saving operation that works well in larger horizontal openings. Designed for retrofit applications, this window includes a flush fin (TMF) for a clean, secure installation into existing openings without the need for full-frame replacement. With a durable, low-maintenance vinyl frame that resists moisture, warping, and fading, plus energy-efficient dual-pane insulated glass featuring Low-E Over Clear glass for improved thermal performance and noise reduction, this window delivers reliable comfort and long-term value for residential applications.Specifications
