Sliding Sash Windows

The classic window style. Sliding sash windows became popular in the Georgian period and were the window of choice for the following two centuries. They reached their peak of popularity in the Victorian era and can be seen on houses across the UK. In the 21st century, sliding sash windows have seen a resurgence in popularity and are now being used in both period property replacements and in new build homes. Our vertical sliding sash windows combine the traditional style of many period properties with the modern performance provided by today’s technology.

Traditional features modern performance

When it comes to traditional styling, it’s all in the detail. At FineLine, we’ve developed timber and uPVC sliding sash windows which faithfully replicate a wealth of period detailing. From classic sash horns to astragal bars, their authenticity won’t be beaten. In terms of performance, our sliding sash windows are secure and energy efficient, sure to improve your home’s performance.
