Casement Windows

Casement windows are easily recognized because they open outward allowing light and air into the building. This type of window, when closed, creates a tight seal for increase energy efficiency that will help you reduce your electricity costs. Casement windows are easier to operate because they contain a slide rail mechanism that carries the weight of the window. This type of window is more common in newer homes and more typical in the western part of the United States. They’re the perfect choice above cabinets, counters, or areas where opening and closing require a reach to crank them outward and direct the fresh air indoors.

Casement Windows can be customized for precise size, desired color and materials such as wood, steel, fiberglass, aluminum, and vinyl. A variety of design features can also be added to Casement windows such as grill, muntins etc.

Although all casement windows have the same components, there are three different types:


Consist of a single frame with panels of glass known as lights, separated by wooden strips that open out or in, depending on how they’re mounted.


Originally called French casement windows, they consist of two windows hinged on the sides that swing out and meet in the middle. Double casement windows are more expensive than single, but they add an elegant touch to the home.


Come in both single and double styles and use a handle instead of a crank.

Advantages of Casement Windows

  • More Ventilation: The Casement window sash can be fully opened outwards, and therefore allow more air than the double hung windows which can only be half opened.
  • More light : The Casement windows offer more light per opening than double hung windows, thereby giving a room a brighter, more airy feeling.
  • Better air filtration: The Casement windows offer better air infiltration factors than double hung windows when properly built and fitted.
  • More energy efficient: The window sash presses against the frame on closing, creating an airtight seal which prevents air entry and leakage. So, the Casement windows are the second most energy-efficient, after fixed-pane windows.
  • Noise reduction: Since the Casement window is sealed all the way around when shut, it boasts of good noise insulation.
  • Easy to open and close: Because they use single-lever latches or tandem latches, casement windows are easy to open and close.

Disadvantages of Casement Windows

  • Obstruction: Because it swings out, a Casement window won’t work near a walkway or a deck.
  • Can’t accept air conditioners: Because casement windows crank outward, they can’t accept air conditioners.
  • Can’t use screens: Since casement windows crank outwards, and the opening cannot be obstructed, fly screens or storm windows are not suited.
  • Size limitations: Casement windows can’t be too large or too heavy because the opening has to be strong enough to support the window sashes.
