What Is The Difference Between Casement Windows and Sash Windows?

Are you looking to upgrade your windows but can’t decide between casement windows and sash windows? Casement windows and sash windows are the two most popular designs for homeowners in the UK, but we are here to give you a run down of all of the additional benefits that you can enjoy when you choose sliding sash windows from Sashes of Surrey.

Casement Windows

Casement windows are the most common window design in the UK. They operate o one or more hinges allowing you to swing the window open, outwards away from your home. There are several configurations, the most popular being side-mounted hinges or top hung.

They are usually fitted in single or double panes, limiting the size of windows you can have. Because casement windows open outwards, the frame needs to be able to support the weight of the window so they cannot be too large or heavy. It also means that you cannot put screens or storm windows on the outside.

Sash Windows

Sash windows, on the other hand, operate on a vertical sliding mechanism. They consist of two framed window sashes that move up and down rather than outwards. They feature vertical grooves which prevent damage to the windows when operating them and sash stops so that you can secure them whilst ajar to ventilate your home without the worry that they can be forced further open, granting access to your home.

Traditionally sash windows feature glazing bars designed to hold smaller glazed panes together, however, modern designs tend to feature bars placed on top of double glazing to replicate the heritage charm. Unlike casement windows, sliding sash windows do not have hinges or open outwards, however, some modern designs feature a tilting operation to assist in cleaning.

uPVC Sash Windows

uPVC sash windows are reminiscent of Georgian and Edwardian architecture but with added durability and longevity. Traditionally sash windows would have been made using timber, but many manufacturers now use uPVC because it is an affordable and effective timber alternative.

At Sashes of Surrey, we work with market-leading manufacturers, Roseview, to provide our customers with some of the best uPVC sash windows available in the UK. uPVC is strong and resilient, so it can withstand harsh conditions without needing to be repaired or replaced for up to thirty years!

Timber Sash Windows

Alternatively, we also have a stunning selection of authentic timber sash windows so that you can replace your windows with classic frames with modern performance. Unlike older timber windows, our sash windows have been manufactured with innovative features to protect the wood against moisture damage so that they can last longer. In fact, if maintained properly, timber windows can last longer than uPVC alternatives!

One of the biggest benefits of choosing timber is that it is one of the most sustainable options. Our wooden sash windows can be recycled and reused rather than ending up in landfill. Plus, wood naturally absorbs carbon from the atmosphere, making it an eco-friendly option.

Benefits of Sash Windows

Stunning Aesthetics

Whether you have a heritage home or a modern new build, sash windows suit all property types. What makes them so unique is that there are so many ways that you can customise them with ornate window furniture and finishes. We have a stunning range of colour options, including wood effect foils for our uPVC vertical sliders so that you can get the look of timber with added durability.

Additional Security

Sash windows also offer enhanced security compared to casement windows. Whilst they feature all the same home security features as casement windows, like strong locks and anti-jemmy bars, they also have sash stops that secure the window to the frame so they cannot be forced open. You can also opt for sash screws which work by locking both frames together by screwing into the top and bottom rails, which is particularly safe for children’s rooms.

Thermal Insulation

It is a common misconception that sash windows do not offer the same level of thermal insulation as casement windows. Whilst this may have been true a couple of decades ago, modern sash windows feature tight weather seals that prevent heat from escaping and cold draughts from getting in when the windows are closed. Plus, both uPVC and timber offer exceptional thermal performance, helping retain heat within your home. So much so that you can even save money on your energy bills by reducing the amount you rely on central heating.
