What is the primary function of a sash in window construction?

1. To regulate temperature inside the building

2. To hold the glass in place and enable window operation

3. To enhance the aesthetic appeal of the window

4. To provide a barrier against wind and rain

The correct answer is: To hold the glass in place and enable window operation

The primary function of a sash in window construction is to hold the glass in place and enable window operation. The sash serves as the framework for the window, providing the necessary support and structure to contain the glass panes securely. It allows for the window to open and close, facilitating ventilation and ease of use. The design of the sash also includes mechanisms such as pulleys and springs that contribute to the window's operability, whether it's a sliding, double-hung, or casement window. While temperature regulation, aesthetic appeal, and providing a barrier against elements like wind and rain are important aspects of window performance, they are not the fundamental roles of the sash itself. The sash primarily focuses on holding the glass securely while allowing the window to function effectively.
