A vertically sliding window with two operating sashes for flexible upper and lower ventilation. The operation is useful where an outward-projecting sash would interfere with a walkway, deck or planting. Available systems use vinyl construction and insulated glass, with screen, tilt and hardware details varying by the selected configuration.
Product media
Use these views to compare proportions and visible details. Final colours and components are confirmed for the measured configuration.
Selection guidance
Two vertically moving sashes allow ventilation at the upper sash, lower sash or both. This operation suits traditional proportions and avoids exterior projection, while the centre meeting rail and sash reach remain visible practical differences.
Product details
These documented characteristics provide a starting point; the measured configuration determines the final specification.
Complete project scope
Measure the opening, confirm reachable sash heights and review screen, balance and cleaning access. Glazing, exposure ratings and installation details must match the quoted double-hung size rather than a generic style label.
Continue comparing
Compare it with a single-hung window when one moving sash is enough, or with a double slider when the opening is wider than it is tall.
A vertical-sliding window with one operating sash and one fixed section. It provides familiar proportions without projecting into exterior space, making it useful beside paths, porches and planting.
A horizontal window with two sliding sashes, allowing ventilation from either side without projecting indoors or outdoors.
A horizontal-sliding window with one operating sash and one fixed section. It provides ventilation without an outward-projecting sash and works well in compact rooms or beside exterior circulation areas.
