Casement vs Double-Hung Windows

31 January 2023

When choosing windows for your home, two popular options are double hung and casement windows. While both have their own unique benefits and drawbacks, the best choice for your home will depend on your specific needs and preferences.

Double-Hung Windows

Double hung windows are characterised by two sashes that slide up and down within the frame. This design allows for easy ventilation and cleaning, as both sashes can be opened to provide a clear path for fresh air to flow through the room. Additionally, the ability to tilt the sashes inward makes cleaning the exterior of the window much easier. Double hung windows are a great option for homes with children or pets, as they eliminate the need to open the window outwards, reducing the risk of falls.

Casement Windows

Casement windows, on the other hand, feature a single sash that swings out from the frame, much like a door. This design offers a wider opening than double hung windows, which can provide better ventilation in certain situations. Casement windows also typically have a more streamlined look than double hung windows, as there are no overlapping sashes to detract from the overall appearance. When closed, the seal on a casement window is often tighter than that of a double hung window, reducing air leaks and improving energy efficiency.


When it comes to installation, casement windows can be more complex to install than double hung windows, as they require additional hardware and hinges to allow the sash to swing open. However, the additional hardware also provides greater security, as the window can only be opened from the inside, making it more difficult for intruders to enter.

Both double hung and casement windows have their own unique benefits, and the best choice for your home will depend on your specific needs and preferences. When choosing between the two, consider factors such as ventilation needs, ease of cleaning, and overall appearance. By weighing the pros and cons of each option, you can be sure to choose the best windows for your home.
