What are Casement Windows?

Casement windows are a nice alternative to the regular and sash windows. Casement windows are mounted in a different way than their regular counterparts – the hinges are side-mounted and pivot open and closed vertically during the rotation of an internal crank. Granted, casement windows are not perfect for everybody, but that’s exactly the reason why we’re offering a large variety of products. Let’s take a look at both the advantages and disadvantages of the casement windows.

Advantages of Casement Windows

Casement windows hold one pretty significant advantage over the other types of windows. Cross ventilation is a very viable way of cooling your home in the hot months of the year. This is why you need a window that can be opened as much as possible. Casement windows meet this need better than their counterparts – no other window can be opened as much. They swing open entirely, not just parts of them. Let’s give a small comparison to other window types:

  • Fixed windows never open. Needless to say, if you need fixed windows, you won’t be checking any other types.
  • Sliding windows are great in their own right, but only one of their sides is able to be opened. The other side is fixed most of the time.
  • Double hung windows are half as effective – only the top or the bottom half of the window can be opened, but never both of them.

However, you should keep one thing in mind. Casement windows open wide – and that gives way to various insects into your home. If you would like to counter this downside, consider getting insect screens to every casement you own. Doing this early can save you lots of headaches along the way.

Casements don’t make use of muntins. Some people like them, some hate them with a passion. If you are from the second type of people, you are in luck. If you are considering dual-sash casement windows, the only thing getting in your view would be the window frame strip between the two sashes. With single-sash casements, there is nothing in the middle – just the great outdoors.

Casement windows can catch the side breezes. The wind sometimes moves along your house at weird angles. With most types of windows, it’s tough getting the air flowing in your home. The open sash of the casement windows can act as a funnel when it comes to wind. It can easily funnel the breeze inside your house and start that sweet cooling process.

Casement windows are quite good when it comes to security. Their locks are in the shape of a hook, and those hooks are embedded within the frame itself. This alone makes them untouchable from the outside. To compare with double-hung windows – they can be easily broken into by using a slim pry bar. The lock screws then get pulled out from the wood and bam – you have unwanted guests.

Disadvantages of Casement Windows

Casement windows have quite a few advantages over other window types, but they are not perfect. They have several disadvantages compared to slider windows and double-hung windows. Let’s take a look at them.
  • Casement windows have more mechanical parts that could potentially break. Most of the casements have a crank which is used to open and close the sash. At some point, you will need to change the crank. Handles can break, gears can freeze – all of these mean that you may need to change the whole unit. The other two types are superior in this regard.
  • If you install two casement windows side by side, the sashes may conflict if the swing is reversed. This, however, is a very loose idea. No homeowner or installer who knows what they are doing will allow this to happen. But having two casements installed in a corner? That’s a whole different story.
  • Conventional A/C units will have a hard time fitting in casement windows. Most of them will not fit at all. A sliding sash can close down and seal off the window, but a casement cannot do this.
  • Conversely, you will have to install a more expensive A/C unit. 12000 BTU units are a good fit for such occasions, but can cost a lot more than the budget units.
  • The open casements are more exposed to the natural elements. As we already established, the sashes open outward. This makes them always exposed to rain, snow, sun and more. The top edges suffer the most and become beaten by the weather faster. Think of this and the material you are going to have your casement windows made of.
  • Since the casements open to the outside, you will have to install the insect screens on the inside. This is usually okay, but becomes a problem if you have dogs, cats, or children who like to stand near the window and look outside.
  • The casement sash can reflect the sun quite badly in some cases. Of course, for darker rooms, this can be an advantage. It’s all subjective, but most of the time the strong sun reflection is considered a minus.
  • Open casements can break, especially during big storms. Always make sure to close the windows before strong winds – you don’t want to find them broken off at some point.

The verdict here is clear – if you need the positives of a casement window, you will have to live with the negatives. If you need weathertight windows which can be opened – casements are your best choice. The window seal meets the sash straight on and does not allow any air infiltration. Casement windows also force more air in the house. These two features make them amazing for both cold and warm weather.
