A window sash is the moving part of the window that keeps the glass panes together inside the frame
If you’ve ever cracked your home’s windows to let in the outdoor breeze, there’s a window sash to thank for it. Window sashes hold the glass in place within the frame, allowing the window to move up or down.
What is a Window Sash and How Does It Work?
So, what is a window sash? The term “sash” is somewhat confusing here, as many of us associate it with a piece of clothing worn while selling cookies or competing in a beauty pageant. However, in the case of windows, forget what you know about sashes and stay with us.
The window sash is the moving part of the window that contains the glass. The window frame is the immobile component that’s attached to your home.
Window sashes slide vertically using a set of cords and weights or spiral balances, which allows them to maintain a smooth, controlled movement as they open and close. There is usually a top sash and a bottom sash, which lock together at mid-range to prevent the pane from sliding out of place.
Double-Hung Window Sashes
Most window sashes come in the double-hung style of window, where an upper window sash is above a lower sash. Both sashes remain parallel to one another, with the lower window sash able to slide up or down. In many newer windows, the upper sash can slide in either direction as well.
Casement Window Sashes
Unlike the double-hung window, which slides up and down, casement windows open and shut like a miniature French door. Most will operate with a crank, while a select few allow you to open or shut them with your hands.
Aside from the bonus arm workout, these types of window sashes have a few advantages:
- They allow you to fully open the window, whereas double-hung windows only allow half at a time.
- They provide superior airflow, with the open window sash helping to channel in more fresh air.
- They allow for an obstruction-free viewing of your garden, kids, bird feeder, and all the other joys of your outdoor space (without the window sash meeting rail getting in the way).

Sash Window Pros Vs. Cons
Just like anything else you pick out for your home, sash windows have their benefits and potential shortcomings. Below are the top pros and cons for these types of windows.
Pro: They’re Energy-Efficient
Most sash windows feature an insulated glass unit (IGU), two or more flat panes of glass with a sealed pocket of gas in the middle. As the name suggests, this provides extra insulation, which could save you big on your energy bills.
Pro: They’re Attractive
Double-hung windows have a sleek look, while casement windows add an extra touch of country charm. Either way, fresh air is always a good look.
Pro: They Allow Fresh Air
Both double-hung and casement window sashes allow fresh air to come in from the great outdoors. A basic picture window doesn’t open, which would be a real bummer on a nice, breezy afternoon.
Con: Possible Fogging Issues
IGUs on window sashes can potentially fog up due to improper installation or wear. If this happens, a window repair company near you can help address the issue.
Con: Potential Leakage
If you forget to shut your sash windows when a rainstorm hits, you might end up with some water inside your home. This could do a number on your window frames, especially if they’re made of wood.
Aside from that, the seals of your sash windows could malfunction due to deterioration or improper installation. Again, this equates to water seeping in when it rains, so consider having a pro take a look if it happens.
How to Maintain Your Sash Windows
You’ll save future window repair costs if you inspect and maintain your windows regularly. Window sashes aren’t too demanding in the maintenance department, but do keep a keen eye if they’re made of wood. Otherwise, check your sashes every month or so for signs of mold, mildew, damage, and deterioration.
If your window sashes develop any problems, you don’t always have to front the cost for a complete window replacement. There are repair kits available that can have your sashes looking as good as new for a fraction of the price.
