Windows come in all shapes and sizes and can be tailored to your specification, but choosing the right style is a little trickier. To help you make your choice, we compare the features and advantages of two of the most common window styles on the market: Casement Windows and Sliding Sash Windows.
What is a Casement Window?
Casement windows are attached by two or more hinges at the side. They can open inwards or outwards, but more often they open outwards. They may have a ‘friction hinge’ or ‘stay’ to hold the window in place when it’s open. This is handy on windy days!
They often come in PVCu frames, making them more modern in appearance and perhaps more suited to modern homes. However, casement windows are available in wooden frames and a choice of colours in PVCu, making them quite a versatile window.
Casement windows can be singular or in pairs sharing a frame. The glass may be plain or can have the appearance of leaded glass: i.e. panels of glass held together with lead strips, creating a criss-cross pattern, or with a Georgian bar pattern.
Advantages of a Casement Window
- These windows are safe to open in the wind because there is a safety catch holding them in place. Inward opening casement windows can be fitted in areas with very windy weather as an extra precaution.
- You can create lots of different looks with a casement window. They can be purchased in a choice of frames, which means they can suit more homes and tastes and they are available in plain, leaded glass, or Georgian style.
- These windows are suitable for modern developments, refurbishment, or the replacement of existing casement windows.
- They’re very secure because the lock is embedded within the frame, making them difficult to break into.
- Want to save money by insulating your home? Casement windows are very energy efficient and are second only to fixed-pane windows in terms of energy efficiency.
- These windows offer excellent ventilation to homes because they open outwards, allowing air and light in from the top, the bottom and either side. In fact, this type of window can open the widest compared with all others.
Considerations – White PVCu can look out of place next to older building materials, so consider a wood effect PVCu frame for period properties.
What is a Sliding Sash Window
Sliding sash windows are not attached with by hinge. Instead they slide open – either up or down, or side to side.
Original sliding sash windows are a really strong selling point of many period properties. They’re one of those features like ‘original fireplace’ or ‘Aga’ that get homebuyers really excited. However, original sliding sash windows can be expensive to maintain and repair and if they’re single glazed, they’re less energy efficient.
We recommend replacing older and damaged sliding sash windows with newer ones, in a material that’s sympathetic to the building’s materials.
- They’re attractive and can make your home appear more beautiful and more valuable.
- These windows are useful in period properties when casement windows may be considered too modern. Sliding Sash Windows are available in PVCu and wood.
- They are suitable for period developments, refurbishment, or the replacement of existing sliding sash windows.
- You can choose how much to open the window by sliding. This means you can have it open just a tiny little bit if you just want to keep some air flowing through the room, or keep the Great British weather out!
- These windows are easy to open.
- You can choose different styles for these windows, which are available in plain glass, in leaded glass (the criss-cross pattern), or in panels.
Considerations: Be careful when painting original sliding sash windows, because doing so incorrectly can make the windows stick.
