Sash Windows

Sliding sash windows are a timeless favourite…

Sash windows are perhaps the most common type of window found here in and around Berkshire, Hampshire & Surrey. First introduced in the late 17th century, they remained popular across the Georgian, Victorian, and Edwardian eras, as such they can be found in many different styles of home right across the country.

Perhaps the most notable feature of Sash Windows is how they open and close. They feature two panes of glass positioned in vertical grooves that slide up and down; one in front and one behind. This motion is made easy by the use of a simple yet highly effective counterweight mechanism. Traditionally made from lead, counterweights found in modern windows now feature durable, energy efficient springs that enable the windows to be opened and closed incredibly easily.

The grid style design of Sash Windows makes them instantly recognisable. Consisting of a grid of small glass panes held together by bars, the number of panes is often varied and therefore ensures your choice of window is unique. ‘Six over six’ and ‘eight over eight’ patterns are associated with Georgian-style homes, while a ‘two over two’ pattern is more common in Victorian era houses.


Your home needs the perfect replacement windows…

We try to get in the minds of our customers and always ask them their reasoning for replacing their existing windows. The most common responses are that they have grown tired of looking after them or they want to improve thermal efficiency and cut the cost of energy. We will pose you with the same question when you make an appointment with TradeMark so that we’re completely clear about the sort of replacement windows you need.

Functionality - The versatility of a sash window is one of its biggest attributes. We also have window styles that open from the side or top, vertically slide and tilt and turn. The best way to find a favourite window style is to try out each window in our showroom where you will discover a fantastic window showcase. You’re always welcome to speak to a window consultant if you need advice on any of our windows.

Guarantee - A sash window from TradeMark comes with comprehensive cover – a 20 year guarantee, double the industry standard. Knowing that you won’t have to dig into your own pocket to rectify any problems with your windows is good to know, not that our windows are likely to cause you any issues!
