What is a Window Sash, and Why Does It Matter?

When homeowners look at their window, they typically look at the whole. They don’t think much about the individual pieces or what goes into making that window function. But if your window is in need of repair, it helps to know all the different pieces and what role they play in a good window. That’s why today we’ll discuss what a window sash is and why it matters so much to the usefulness of your window.

Introduction to Window Sashes

The window sash is the part of the window frame that holds the glass in place. In double-hung or single-hung windows, you often have moving window sashes: single-hung windows have one moving sash, while double-hung windows have two fully operable window sashes moving in opposite directions. In awning and casement windows, the sashes move outward rather than up and down. In other window style, such as fixed windows, the sashes aren’t meant to open.

Why Window Sashes Matter

Window sashes are important for a number of reasons. For one thing, they’re responsible for holding in the window glass — inarguably the most important part of your window. If they become distorted, the window itself can fall apart. Movable window sashes are also good for ventilation and energy efficiency. You can open them to let in fresh air. When you close them, they should keep heat from escaping and creating drafts in your home.
