How it worksMovable lower sash
- How it opens
- The lower sash moves vertically while the upper sash remains fixed.
- Often considered for
- Straightforward vertical openings and homeowners comparing a simpler operating style.
- Keep in mind
- Ventilation comes through the lower portion, and access to the upper exterior glass varies by location.
How this style fits a home
Straightforward operation with a fixed upper sash
Single hung windows retain the familiar look of a two-sash vertical window while limiting operation to the lower sash. They do not need exterior swing clearance and can fit many common residential openings.
The fixed upper sash means less ventilation flexibility than a double hung window. Cleaning access, egress requirements, available sizes, and published ratings should be reviewed for the actual opening.
No outward swing
The sash stays within the frame, which can be helpful near walkways, landscaping, or exterior obstructions.
Upper-glass access
The exterior of the fixed upper pane may require outside access depending on the installation location and product design.
