A window pane is commonly referred to as the transparent material found within a window frame that allows natural light into a room. Synonyms for this term include glass, glazing, sash, framework, and casing. The glass in a window pane is typically made from materials such as tempered glass, double-paned glass, or even stained glass. The surrounding framework or casing can be made from materials such as wood, metal, or vinyl. No matter the specific terminology, a window pane serves an important purpose beyond just aesthetics, providing a clear view of the outdoors while also keeping the elements outside.
