Casement windows have a long history. Until the sash (moveable panel) was invented in the 17th century, casements were the most widely used windows, although they were very primitive compared to today’s products. Once the sash was introduced, single and double-hung windows became the rage.
In the 20th century, with the introduction of newer, more functional, and lower-maintenance materials like aluminum and vinyl, and the development of better hardware, sliders and then casements took over a large portion of the market.
Today, although casement windows are probably the most widely used, single and double-hung windows have also benefitted from new technology and have once again become another popular choice.
Thanks to technology, today’s windows, in any style, are far superior to windows of the past, and choosing the right style is mostly a matter of personal taste.
These are the most widely used, largely because their simple design, with added customization, makes them adaptable to any décor, from traditional to rustic to contemporary.
- When closed, the sash compresses the weatherstripping on the frame for a very airtight seal. This compression also creates a quieter window.
- Very easy to open and close. The hardware in our casement windows has only one lever that operates a triple catch mechanism.
- Offer more ventilation than other options because the entire window area opens.
- Better security than sliders or double hung, because the locking mechanism can’t be accessed with a pry bar.
- Depending on the model, they may be suitable for use as egress windows.
The only major disadvantage is that if the sash is too large and heavy, or the hardware isn’t heavy duty, casement windows can sag under their own weight. This causes problems with operation, air tightness and ultimately, longevity.
Fixed or Panoramic Windows
Fixed windows, sometimes referred to as fixed casements, are most often used as a complement to casement or awning windows, or for shapes other than rectangular. Typically, when there are two or more windows placed together, only one is an opening one, while the others are fixed.
- Few design limitations. Fixed windows can be fabricated in curved and irregular shapes for more architectural freedom.
- Because they’re non-opening, they are the most airtight, energy-efficient style available.
Casements and fixed windows are also the windows of choice for bay and bow windows.
Awning windows are similar to casement windows and provide the same level of energy efficiency as casement windows. They also provide excellent ventilation. The only major differences are:
- Awning windows open horizontally instead of vertically.
- They can remain open in the rain.
