What is a single hung window?
A single hung window has one moving sash—usually the lower sash—while the upper sash stays fixed. It looks similar to a double hung window, but it opens only from the bottom.
Best for
- Homeowners who want a classic, familiar window style.
- Rooms where simple bottom ventilation is enough.
- Projects where value and reliability matter (fewer moving parts than double hung).
Key benefits of single hung windows
- Classic appearance that fits many home styles.
- Straightforward operation with fewer moving parts.
- Strong everyday performance when installed with proper sealing and insulation.
- Often chosen as a value-friendly alternative to double hung windows.
Single hung vs. double hung (quick note)
Both styles look similar, but double hung windows have two operable sashes for more ventilation control, while single hung windows open only from the bottom. If you want maximum airflow options or easier top-to-bottom ventilation control, double hung may be a better fit; if you prefer simplicity and value, single hung is often the right choice.
Common reasons homeowners replace old single hung windows
- Drafts near the frame or noticeable temperature swings near the window.
- Fogging between panes (often linked to seal failure in insulated glass).
- Sticking sash, worn balance system, or a window that won’t stay open.
- Water staining around trim or signs of moisture issues near the sill.

Frequently Asked Questions (Single Hung Windows)
1) Are single hung windows energy efficient?
They can be energy efficient when the window is properly built and installed with correct sealing and insulation. Fewer operable sections can also mean fewer potential air-leak points compared to more complex designs.
2) Why is my single hung window drafty?
Drafts often come from worn seals, gaps around the frame, or older installation details. An on-site assessment helps determine whether adjustment, component repair, or full single hung window replacement is the best fix.
3) What causes fogging or condensation between panes?
Fogging between panes typically indicates a failed seal in the insulated glass unit. Condensation on the interior side may also be influenced by indoor humidity and ventilation.
4) Why is my single hung sash hard to open or won’t stay up?
This can be caused by worn balances, friction issues, paint build-up, or slight frame shifting over time. During an estimate, the sash movement and frame condition can be checked.
5) Should I choose single hung or double hung windows?
Single hung offers simple operation and value; double hung adds more ventilation flexibility because both sashes can open. The best choice depends on where the window is used and what functionality matters most.
