Double hung windows are a classic, versatile choice for many homes because both sashes operate. You can raise the lower sash, lower the upper sash, or open both for comfortable airflow control.

What is a double hung window?
A double hung window has two movable sashes that slide up and down independently within the frame. The sashes meet in the middle and typically lock at the center latch.
Best for
- Bedrooms and living spaces where you want flexible ventilation options (top, bottom, or both).
- Two-storey homes where ease of cleaning and maintenance matters (many modern designs support tilt-in cleaning).
- Homes that suit a traditional look without sacrificing everyday function.
Key benefits of double hung windows
- More ventilation control: open the top to release warm air and the bottom to bring in cooler air.
- Easy maintenance: many double hung designs include a tilt-in/tilt-wash option for cleaning from inside.
- Familiar, timeless style that fits many exterior and interior designs.
- Secure closure when both sashes are shut and latched at the meeting rail.
Double hung vs. single hung (quick note)
Single-hung windows typically have a fixed upper sash and an operable lower sash. Double-hung windows have two operable sashes, which usually improves ventilation options and can make cleaning easier.
Common reasons homeowners replace old hung windows
- Drafts or rattling around the sashes, especially in cold weather.
- Sticky movement from worn balances, tracks, or frame issues.
- Fogging between panes (insulated glass seal failure).
- Water intrusion or interior trim damage around the sill.

Both sashes move: the bottom sash slides up and the top sash slides down, so you can open either section or both.
2) Are double hung windows good for ventilation?
Yes—because both sashes operate, you can fine-tune airflow (for example, vent warm air at the top and pull cooler air from the bottom).
3) Are double hung windows easy to clean?
Many modern double hung designs offer tilt-in/tilt-wash functionality, which allows cleaning from inside the home.
4) Why is my double hung window hard to open?
