Casement windows are a popular choice for many homeowners. They offer a classic look and excellent ventilation. Let's dive into the details of these versatile windows.
Casement windows are hinged on one side and open outward like a door. They provide a wide opening for maximum airflow. These windows are known for their tight seal when closed, making them energy-efficient.
The frame consists of the head (top), jambs (sides), and sill (bottom). It's the window's main structure.
The sash includes the glass panes and muntins (strips separating panes). It's the part that opens and closes.
● Hinges: Allow the window to swing open
● Handle/Crank: Used to open and close the window
● Locking Mechanism: Secures the window when closed
Casement windows open by turning a handle or crank. This motion extends an arm, pushing the sash outward. They typically open to a 90-degree angle.
1. Single Casement: One sash hinged on either the left or right side
2. Double/French Casement: Two sashes that meet in the middle when closed
3. Push-Out Casement: Opens by pushing the sash instead of using a crank
4. In-Swing Casement: Opens inward rather than outward
5. Top-Hung Casement: Hinged at the top and opens outward from the bottom
