What Is a Double-Hung Window?

A double-hung window is a window with two sashes, an upper and a lower, that both slide vertically within the frame. This design allows you to open either the top, the bottom, or both simultaneously for flexible ventilation control.

‍

Double-hung windows offer a classic style that complements many home designs. Homeowners will typically pick these windows for bedrooms or living areas because they are easy to clean and don’t take up any exterior space when opened.

Key Advantages of Double-Hung Windows

Flexible ventilation: The top, bottom, or both sashes can be opened independently to help control air flow.
Easy cleaning: Both of the sashes commonly tilt inward so that you can clean them from inside the home.
Classic aesthetic: This style works well in traditional, colonial, and transitional home designs.
Wide availability: One of the most common window styles; easy to source replacement parts.

Double-Hung vs. Casement: Which Is Better?

Compared to casement windows, double-hung windows offer slightly less airtightness because the sash slides rather than compresses against the frame. However, modern weatherstripping and multi-point locks have significantly improved their energy performance. The right choice depends on your priorities, either casements for maximum energy performance, double-hung for versatility and classic aesthetics.
