Examining Casement Windows: Advantages and Disadvantages

Instead of having a handle and lifting up, casement windows are hinged at the side and crank outward. They’re often installed over sinks, countertops, or appliances, but can be placed anywhere in the home.

Advantages

The advantages of casement windows are:

  • Variety of design features. Casement windows offer a number of attractive design features such as French, flat top, pushout, top down grille, colonial grill, prairie grill, and no grill. They can be customized for precise size and desired color, and they look attractive in a number materials. Typical casement window materials include wood, steel, clad (wood covered with aluminum or vinyl), fiberglass, aluminum, and vinyl.
  • Second most efficient window. Casement windows are the second most energy-efficient, after fixed-pane windows. The window sash presses against the frame on closing, creating an airtight seal. This helps prevent air entry and leakage.
  • Easy to open and close. Because they use single-lever latches or tandem latches, casement windows are easy to open and close. Most models can also be fitted for automatic openers.
  • Excellent ventilation. Casement windows open all the way outward. Unlike double-hung windows, which are closed on top, casement windows are wide open from top to bottom and side-to-side providing excellent natural ventilation and light.

Disadvantages

The disadvantages of casement windows are: 

  • Can’t accept air conditioners. Because casement windows crank outward, they can’t accept air conditioners. Windows that slide up and down can accommodate an air conditioner more easily.
  • Can’t use storm windows or screens. It is possible to find casement windows that crank inward, but this is not a common choice. If you plan to use screens or storm windows, casement windows are not the best option. They crank outward, so the opening canno’t be obstructed
  • Size limitations. Casement windows are designed to crank outward. Because of the design, the windows can’t be too large or too heavy. The opening  has to be strong enough to support the window, so builders recommend smaller and more lightly constructed windows.
