Casement windows are windows mounted on side-mounted hinges, pivoting open and closed vertically as an internal crank is rotated. They are not the ideal choice for some people, but others find the to have several advantages.
Let's give casement windows a fair shake and look at four notable advantages.
They Provide a Fully Open Window
No other window can be opened as far, which can be an important advantage when you depend on cross ventilation to cool your home.
In a lake home, for example, casement windows had a great advantage. When you open a casement window, you swing the entire window open. Compare to:
- Double hung windows, in which only the lower half or the upper half open, but never both.
- Sliding windows, where only one side of the window can open. The other side is usually fixed.
- Fixed windows. Obviously these never open.
So if the size of window opening is important to you, you may want to consider casements. However, be aware that unless your home is equipped with insect screens, casement windows may open far enough to be a hazard to small children.
Few Muntins and Better Views
Muntins are those strips of wood, vinyl, metal, or fiberglass that divide panes of glass within a single window. Sometimes muntins are desired; other times, not. Sometimes, in fact, that fake muntins are installed between the two panes of glass, or as clip-on accessories
If you hate muntins, you're in luck with casements. If you have dual-sash casements, the only strip that separates you from the great, beautiful outdoors is the window frame "strip" between the two sashes. In the event you have single-sash casements, you will have no muntins.
In the accompanying picture, you can see how casement windows can improve a view.
This homeowner went from triple single-hung windows to dual casements. Fewer muntins mean a better view.
Casement Windows Catch Side Breezes
If by some weird trick of nature, breezes move along your house at an acute angle, it's difficult to get any kind of air moving through your house with most windows.
But casements, remember, have that open sash acting as a flap to funnel breezes into your house. For example, if your home is tightly boxed in by neighbors, the angle of the casement windows may allow you to catch breezes that other window styles could not make use of.
Casement windows are very difficult to break into. Casement locks are hook-shaped, and these hooks are embedded within the frame, making them untouchable.
Contrast this with double-hung windows, which are easy to break into by slipping a slim pry bar under the sash and lifting. The sash lock's screws pull right out of the wood.
