Understanding Single-Hung vs. Double-Hung Windows: Choosing the Right Style for Your Home

What is a Single-Hung Window?

A single-hung window, also known as a single-sash window, features a movable lower sash and a fixed upper sash. This design allows the bottom section of the window to slide vertically while the top section remains stationary. Single-hung windows are ideal for providing ventilation through the adjustable lower sash, making them a popular and affordable option for many homeowners.

What is a Double-Hung Window?

A double-hung window, often referred to as a double-sash window, has two movable sashes that can be opened vertically. This design allows both the top and bottom sashes to slide up and down independently, offering superior airflow. With double-hung windows, warm air can escape through the top sash while cooler outside air enters through the lower sash. This dual ventilation system is especially beneficial for multi-story homes.

Single-Hung vs. Double-Hung Windows: What’s the Difference?

Both single-hung and double-hung windows are designed for energy efficiency, but there are key differences in their functionality. Double-hung windows offer more versatility with dual ventilation, while single-hung windows provide simplicity at a lower cost. For added performance, both types can be manufactured with vinyl or fiberglass frames. Vinyl and fiberglass windows feature multi-chambered frames that reduce heat transfer, keeping your home comfortable year-round. Some fiberglass models can also include optional insulating foam for extra energy efficiency.



Wood-framed single and double-hung windows benefit from natural insulation, further improving your home's energy performance.
