Windows are more complicated than they’re given credit for.
There are dozens of working parts that go into keeping your windows safe, secure, and functional—the window sash being one of the most critical.
Sure, it’s pretty easy to overlook how windows in our home function.
But understanding window design can help you diagnose problems early on, recognize when it’s time for a replacement, and even prevent issues from arising altogether.
So, here’s what you need to know about the unsung hero, the window sash.
First of All, What Is a Window Sash?
Let’s go back to the basics.
To the unobservant eye, windows look something like this:
- A large frame (built into the house)
- Smaller frame/frames fitted inside
- Glass panes
Well, the window sash is the part that holds the glass panes in place.
In other words, the smaller framed part of the window that, usually, slides up and down to open the window.
The most common example is seen in double-hung windows, where one sash (framed glass pane) is positioned directly above the other.
The bottom sash glides up and down and, often, the top sash is fixed in place.
So, Why Are Window Sashes Important?
Aside from allowing us to open and close our windows, window sashes can indicate issues arising with your windows.
See, it’s imperative to understand how the window sash functions and the signs that it may be time for a fix or replacement.
After all, a nonfunctional window lowers the value of your home at best, and is a risk to your family at worst.
Identifying Different Window Sashes
Most modern homes have window sashes, regardless of the style.
We already spoke about double-hung windows, where one sash window is positioned above the other.
Traditionally, the top sash was fixed in place, although it is becoming more common for both the bottom and top sashes to be movable.
This allows the top window sash to glide down to let fresh air inside the home—which avoids the safety hazard of children falling through open windows.
Sider windows, on the other hand, only have one sash and glide horizontally rather than up-and-down.
And finally, casement windows open with a crank, therefore only utilize one sash window as well.
The Risks of a Problematic Window Sash
There is a long list of reasons why you should pay attention to your window sashes, as a faulty sash can result in drafts, leaks, and windows that are distorted or stuck in place.
If you have any of these issues, there’s a chance your window sash could simply be repaired; however, older windows may require or benefit from a complete replacement.
While the initial cost may be high, your energy bills, home value, and safety add up to a full return on your investment.
