Window Types & Styles

Single-Hung Window

Single-hung windows feature two sashes—the frame sections that hold the glass. The upper sash is fixed in place, while the lower sash moves vertically, sliding up and down. This vertical configuration gives them a rectangular shape and ensures they do not protrude outward when opened.

Because they remain flush with the wall, single-hung windows are ideal for rooms facing narrow walkways or streets, as well as compact areas where reaching a top sash would be impractical—such as above a kitchen sink or bathtub. They are among the most common window styles used in new builds, offices, and multi-unit residences.

Single-hung and double-hung windows fall under the broader category of sash windows, a style with origins in Georgian and Victorian England.

 

Double-Hung Window

Double-hung windows share the same basic design as single-hung windows, but both the upper and lower sashes are operable. Each sash can move independently and tilt inward, providing superior ventilation and making cleaning more convenient. This versatility makes double-hung windows well-suited for spaces where airflow is a priority—such as bathrooms, kitchens, and bedrooms—and they can be crafted from a wide range of materials, including wood, aluminum, fiberglass, and vinyl.

A timeless design, double-hung windows have enhanced homes for centuries, adding both beauty and character. Their adaptability allows them to complement virtually any architectural style, from classic and traditional to sleek and contemporary.
