Casement Windows

Casement windows operate much like a door. Either the left or right side is hinged while the other side that is not hinged locks securely into place with latches. However, unlike a door, a casement window can be opened through some variation of a crank rather than a knob or handle. The cranks or levers also serve as the lock for the windows.

Casement windows or casements are windows that are attached to a frame through one or more hinges.

Casement windows offer several benefits. Among others, they can be very weathertight. This is because the seal of the casement windows directly meets the sash as compared to slider windows in which their seal simply slides. Also, their design allows more air to get into the house. Moreover, they can be opened even in the midst of strong winds as they are designed with a friction hinge, crank, or casement stay. They are also quick and easy to clean simply because they swing to open allowing easier access.

Among the different types of casement windows, the French casement is the most popular. It is especially designed to open up unobstructed in the middle. Casement windows are ideal choices for rooms with windows in hard to reach areas like above countertops and cabinets.

While casement windows have long been past their prime, they are still very much present in many homes up until today. They can be installed either as a single unit or grouped together to form a unique arrangement.
