What is the purpose of a sash in a window?
To frame the outer structure of the window
To provide insulation
To hold the glass in place
To prevent air leaks
The correct answer is: To hold the glass in place
The purpose of a sash in a window is to hold the glass in place. A sash is essentially the framework that supports the panes of glass and allows them to move up and down or side to side, depending on the type of window. This component is crucial for the overall functionality of the window, as it secures the glass and maintains the structural integrity of the window unit. In addition to holding the glass, the sash also plays a role in the aesthetic appeal of a window and may serve as a barrier to environmental elements when properly constructed. Understanding the role of the sash is important, especially in contexts like lead inspection, where the condition of the sash can affect overall window performance and safety.
