Casement Windows and Sash Windows, which is better?

Prices & Design Options
Here is a comparison of the main features of Casement Windows and Sash windows that will give you a good grasp of the basics.
Casement Vs Sash Windows
The 2 biggest, and most obvious, differences between Casement & Sash windows is the way that they function and the way that they look.
- Classic Sash windows open and close by sliding up and down on a track within the main window frame.
Typically, there will be 2 moving panels, or sashes, one set above the other. One or both of the Sashes can be fitted to move. A single hung window will only have the lower section movable. A double hung window will have both sections able to slide.
- Casements swing open and closed via hinges on one side of the window frame.
The standard casement window will swing open outwards, like a door. However, you can have hinges fitted to the top to create an “Awning Casement” or to the bottom to create a “Hopper Casement”. Hoppers should open inwards, Awning open outwards.
There are a couple of pros & cons to each method of opening.
You will have to reach out (maybe even stretch a little) to open a casement to its’ maximum. Whereas with a sliding Sash, you won’t need to do that, just slide it up or down.
Sashes tend to give a wider opening, and this can be useful as a means of escape in an emergency. However, it also means you have to be aware about the potential of a child climbing out or an intruder climbing in.
Because casements are hinged the hinges take all the weight of the window and so they are easy to open & close.
On the other hand, the weight of a sash has to be counterbalanced in some way. Counterbalances are either via ropes connected to weights which are hidden within the outer frame, or spring loaded tension mechanisms.
This can make the windows stiffer to move and so it requires more effort to open & close them. It also means there are more things to maintain and more things that can break or malfunction over time.
Because a Sash window needs some form of counter balance mechanism built into the outer frames, it will result in those frames being thicker (chunkier) than for the average Casement window.
To a greater or lesser extent (dependent on the dimensions of your frames), this thicker frame will have the potential to reduce the amount of natural light available. So if you want a lighter, more slimline appearance, then you will be better off with the Casement Style.
If you like the look of a classic Sash window, but are not a big fan of chunky frames, then an option could be to use a “Faux- Sash” casement window. Externally it looks identical, but uses a top hinged awning casement in place of a sliding sash.
The drawback with this option is that, typically, only the top section will open.
Comparing Casement Windows and Sash Windows – Prices.
This is an area where there is a significant advantage for Casement windows, in that for a similar sized unit, Casements are lower priced than Sashes.
Typical windows prices by design:
- Average casement windows cost from £250 to £600
- Average Tilt & Turn casement windows cost from £450 to £700
- Average Sash windows cost from £500 to £900 (UPVC to Hardwood Box Sash)
As you can see, there is quite a difference per window, and if you are considering replacement windows for the whole property, the extra cost of fitting Sash windows could add up to a significant amount.
Unless there is a particular overriding reason (planning, listed building, regulations) to fit Sash windows to your home, then Casement windows represent a better choice in terms of cost.
However, as mentioned before, a good alternative option if you like the visual style of a Sash window but don’t have the budget for an original, could be to consider fitting the Faux-Sash style.Get Quotes Here
