Built around a reinforced tubular aluminum frame with three independent channels, this vertical unit pairs upper and lower glass panels with two fiberglass screens divided by a fixed meeting rail. The hollow-tube extrusion resists deflection on tall openings where flat-stock frames tend to flex, and the dual-screen layout lets you ventilate the top, the bottom, or the entire window without compromise. Engineered as a long-service exterior upgrade for owner-occupied homes in mixed-climate regions.
