A casement window, which is hinged either at the left or right side, opens up like doors swinging outwards. Unlike a door, however, this type of window is opened or closed through some variation of a crank, which also serves as the unit’s locking mechanism. The crank handle is typically set at the bottom or at hand height for it to be easily utilized.

Typically tall than wide, casements are ideal to use in basements as well as in difficult to reach areas like over the kitchen sink, countertops, and cabinets. Because of their friction hinge, casement windows have the ability to stay open despite strong winds.

Casements are one of the most weather tight windows, excellent at preventing air infiltration. This is because the seal of a casement directly meets the sash. When left open, they are great at providing ventilation since they help force more breeze into the home.

Another benefit of casements is that they provide maximum security as they are the hardest windows to break reducing the odds of potential break-ins. If ventilation is not required in a room, they should be locked properly.

While they may be past their popular times, casement windows are still top choices of a number of homeowners today. Just like most window types, they can be installed individually or assembled along with other types of windows. Double casement windows are available in several sizes, designs, and can even be customized to suit your needs and preference.
