Vertical Sliding Sash Windows Plymouth
Let us take your home into the 21st century with our vertical sliding sash windows in Plymouth & surrounding areas.
Sliding Sash Windows, the Modern Way
Do you have old, timber sliding sash windows? Eventually, these windows will end up sticking, swelling or rotting – leaving you with high energy bills and water ingress. If you would like to keep the traditional look of the sliding sash, or simply like the style and wish to update your home – whilst reaping the rewards of weather tightness and energy efficiency – our uPVC vertical sliding sash windows are a great alternative.
The triple-chambered profile in the uPVC sliding sashes, allows for thermal insulation which, along with the glazing, provides an ‘A’ energy rating. Available in woodgrain finishes to resemble timber windows or a range of RAL colours to suit your taste, they will last for years.




Staying Ventilated with Style
It is important to keep your property ventilated, all year around. When fitting vertical sliding sash windows to your property, you can open the windows as little or as much as you like, using the simple sliding mechanism.
Cleaning is made easier, as the windows can be tilted inwards. With the safety of families in mind, if you have small children, there are safety catches incorporated in the frame to prevent them from playing with the tilting mechanism. Unlike timber sash windows, maintenance of uPVC versions is simple – all you need to do is clean them to keep your home looking fresh.

Like The Sound of Our Vertical Sliding Sash Windows?
You can make your windows look even more traditional by adding optional sash horns or astragal bars. If the prospect of replacing your windows with vertical uPVC sliding sash windows has sparked your interest, please speak to us to discuss further, or request a quote.
