Full 3¼” Depth uPVC Fusion Welded Frame and Sashes that feature beveled exterior curves that not only have a modern-day look, but also allow for maximum weld surface resulting in superior strength and years of long-lasting performance.
Push Button Spring-Loaded Vent Latches allow both window sashes to remain partially open for ventilation.
The standard screen is equipped with a heavy-duty lift handle running the width of the screen. This gives the screen a clean aesthetic as well as additional strength.
