Casement Windows

Casement windows are a versatile and functional choice for many homeowners, offering a blend of aesthetic appeal, practicality, and energy efficiency. Their design allows for full window opening, providing excellent ventilation and easy operation, making them a preferred option for various rooms and house styles.


Components of Casement Windows

Hinged Sash: The part of the window that holds the glass and is attached to the window frame by one or more hinges at the side.

Crank Mechanism: A common feature in casement windows, allowing the window to be opened and closed by turning a handle.

Push-Out Style: Some casement windows open with a simple push, offering an alternative to the crank mechanism.

Seals and Weatherstripping: Provides a tight seal when the window is closed, enhancing energy efficiency by reducing air leaks.

Locking Mechanism: Typically located on the handle or the side of the window, ensuring security when the window is closed.


Ventilation: Casement windows can be opened fully, allowing for maximum air flow and ventilation. The ability to catch side breezes is enhanced due to the sash acting as a flap to funnel air into the home.

View and Light: With fewer mullion (the strips of wood or metal that divide panes of glass) and a single sash, casement windows offer unobstructed views and let in more natural light compared to other window types.


  • Ventilation: Can be opened slightly to allow for air circulation even during inclement weather.
  • Energy Efficiency: When closed, the tight seal contributes to energy efficiency by reducing air leaks.
  • Placement Flexibility: Can be installed higher on walls, preserving privacy and usable wall space below.


  • Outdoor Space: Must ensure that the window’s outward opening does not obstruct outdoor living spaces or pathways.
  • Cleaning: Exterior cleaning may require access from the outside, which can be challenging for windows installed at higher levels.
  • Best For: Rooms that require ventilation and light without compromising on privacy, such as bathrooms, kitchens, and basements.

Best For:

Homes Requiring Good Ventilation: Ideal for areas that need maximum air circulation, such as kitchens, bathrooms, or rooms facing the prevailing winds.

Energy-Conscious Homeowners: Their energy efficiency makes them a great choice for those looking to reduce heating and cooling costs.

Modern and Contemporary Homes: The clean, simple lines of casement windows complement modern architectural styles, although they can be designed to suit traditional homes as well.
