If you’re having windows installed or repaired, you may have a lot of questions about window sashes. While it’s a vital component of window construction, the purpose of these pieces is often misunderstood. The following guide offers a bit of clarification, while also providing information on when repairs or replacements are necessary.

The Components of a Window Sash

A sash is not just one singular component. In fact, it’s made up of several pieces, which all come together to form an intact window. While the configuration may vary, a sash is usually made up of glass panes, the frame, gasket, gas, and grille.

While glass panes and frames are well known, the gasket, gas, and grille are less so. The gasket is made from pieces of rubber or plastic used to seal the glass within the frame. Gas is injected between double panes of glass for insulating purposes. Accordingly, windows with a single pane of glass are without this component. The grillework is primarily decorative but can also be functional. These are sections of wood or plastic that separate glass panels. Grillework may also be referred to as mullions.

What to Look Out For

There are a few aspects to look for if you suspect your window sash needs repairs or a replacement. Water around your window may indicate a problem with seals. You may also notice fog, which is usually an issue with double or triple-paned glass. In both cases, a full window replacement may be recommended to prevent moisture intrusion.

Cracked or broken glass can usually be addressed by a sash replacement. Broken mullions can sometimes be rebuilt, but it typically depends on the style of your window. If you’re unable to raise the sash or can only do so with difficulty, your best bet may be a window replacement.
