What are Sash Windows?

Sash windows are typically made up of two or more panels that slide vertically over each other within the frame. They are a popular choice for traditional homes and are often found in Georgian, Victorian, and Edwardian properties. Sash windows can be made of wood, uPVC, or aluminium, and they offer excellent ventilation and a classic look. Modern sash windows use double-glazed glass and insulated frames to provide excellent thermal efficiency too.

What are Casement Windows?

Casement windows, on the other hand, have a hinge fixed on one side of the window frame and swing open outwards like a door. They are often seen in modern homes, and they can be made of wood, uPVC, or aluminium. Casement windows are easy to operate and provide excellent ventilation, making them a popular choice for kitchens and bathrooms.

What is the difference between a casement window and a sash window?

The main difference between sash and casement windows is the way they open. Sash windows slide vertically, while casement windows open outwards. Additionally, sash windows are often associated with traditional homes, while casement windows are often seen in modern homes.

Sash windows offer a classic look and are often found in historic properties. They are typically more expensive than casement windows, and they can be more difficult to clean due to their sliding mechanism (although double-hung sash windows can tilt inwards, making it possible to clean the outside of the glass from inside your home)

On the other hand, casement windows are a more affordable option and are easier to clean. They also offer excellent ventilation and can be a good choice for modern homes.

What is a double-hung window?

Most old sash windows were single-hung, which simply means that the top sash of glass was fixed in position and the lower sash was able to slide up and down to open and close the window. In a double-hung sliding sash window, both the upper and lower sashes are moveable within the same box frame. As a result, the bottom panel may be moved up to open the window and the top panel may be moved down to open it.

Sash vs Casement Windows: Which is Better?

Ultimately, the choice between sash and casement window styles comes down to personal preference and the style of your home. If you have a traditional property, are looking for a classic look, or want a modern window replacement for existing wooden sash windows, then uPVC sash windows may be the way to go.

However, if you have a newer home and are looking for an affordable and practical option, modern casement windows may be the better choice.
