Projecting Sash

Definition

A projecting sash is a type of window with sashes that swing either inward or outward.

Purpose

The purpose of a projecting sash window is to provide better ventilation, ease of cleaning, and a wider view. This design allows for more flexibility in controlling airflow and access to the exterior side of the window.

Examples of Use

• In residential buildings, projecting sash windows are often used to improve ventilation in living rooms and bedrooms.
• Commercial properties may install projecting sash windows to enhance natural lighting and air circulation in office spaces.
• Historical buildings frequently feature projecting sash windows to maintain architectural integrity while providing modern functionality.

Related Terms

• Casement Window: A window that is hinged at the side and opens outward or inward like a door.
• Awning Window: A window hinged at the top that opens outward.
• Double-Hung Window: A window with two sashes that move vertically.

Notes

Projecting sash windows are advantageous in areas where external cleaning is difficult, as they allow for easy access from inside the building.
