Standard Single Hung
A classic two-sash layout with a fixed upper sash and a lower sash that raises vertically for ventilation.
Vinyl Single Hung Windows
Classic Proportions, Vertical Ventilation and Space-Efficient Operation
Single hung windows use a fixed upper sash and an operable lower sash that raises vertically, making them a practical choice near walkways, porches, patios and other areas where a projecting window could interfere with the space.
- Lower sash raises vertically for ventilation
- No inward or outward projection
- Available in standard and combined configurations
Best Known For
Vertical ventilation with a traditional residential profile
How They Work
The Lower Sash Raises While the Upper Sash Remains Fixed
Single hung windows open vertically from the bottom. The operable lower sash moves upward within the frame while the upper sash remains stationary, providing controlled ventilation without extending into the interior or exterior space.
The lower sash can also be designed for convenient access during routine cleaning, helping homeowners maintain the exterior glass from inside the room when the selected product configuration allows it.

Configurations
Single Hung Operation Can Be Used in More Than One Assembly
Roger’s product brochure presents the standard single hung format, a single hung assembly with sidelites and a combined single hung and sliding configuration. The correct layout depends on the opening and project requirements.
Single Hung With Sidelites
An expanded assembly that places operable single-hung sections beside a wider fixed center panel for larger openings.
Combined Single Hung & Slider
A project-specific combination that links vertical single-hung operation with a horizontal sliding section in one coordinated assembly.
Where They Work Well
A Familiar Choice for Openings That Need Vertical Ventilation
Bedrooms
Vertical operation works well for frequently used bedroom openings and preserves exterior clearance.
Walkways & Porches
The sash stays within the window footprint, so it does not project into nearby paths or porch areas.
Patio-Side Openings
Single-hung windows provide ventilation without requiring the outward swing clearance of a casement or awning window.
Replacement Projects
Their familiar vertical proportions make them a practical option when updating existing residential window openings.
Selection Guidance
What to Consider Before Choosing a Single Hung Window
Single hung windows are straightforward and space-efficient, but the opening dimensions, desired ventilation, cleaning access and surrounding architecture should still guide the final selection.
Strong Fit When You Need
- Vertical ventilation from the lower sash
- No projecting sash near walkways or patios
- Traditional residential proportions
- Straightforward everyday operation
Review With the Project
- How much ventilation the lower opening should provide
- Cleaning access and the selected sash design
- Whether sidelites or a combined assembly better fits the opening
- Frame, grid, glass and screen choices for the property
Plan the Next Step
Review the Opening Before Finalizing the Window
A single hung window should be selected around the actual opening, desired ventilation, sash access and surrounding conditions. Roger’s Windows can help review those details before the final configuration is chosen.
