Definition & Meaning of "window stile"

What is a "window stile"?

A window stile is the vertical part of the window frame that runs along the sides of the window, connecting the top and bottom sections. It helps support the overall structure of the window, ensuring that it is sturdy and properly aligned. Window stiles are typically made from materials like wood, metal, or vinyl, and are essential for holding the window panes in place. They work with other parts of the window frame to allow for smooth operation, whether the window opens or stays fixed, and contribute to the window’s appearance and durability.
