Sliding Sash Windows

Add elegance and period grandeur to your home with vertical sliding sash windows. Made from one or more movable 'sashes' for maximum ventilation, you can also create the appearance of individual panes with cottage bars. Choose between uPVC Elite, uPVC Classic or Wood frames, then make your choice of colour and fittings.

We make each window individually using your choice of frame and glass. See how easy it is to transform your home and get a quote.

  • Give your home traditional charm with the benefit of modern fittings
  • Smooth to open and draught-free when closed
  • Energy efficient – can help reduce your heating bills
  • Secure – shoot-bolt locks, key locking handles and toughened glass
  • Effective noise reduction – great for keeping out external sounds

Depending on your choice of frame, our vertical sliding sash windows' energy-efficient construction comes with either A-rated or B-rated glass as standard to help reduce your heating bills and keep your home warm when it's cold outside. We even make them so that they tilt for easy cleaning.

It's simple to find the cost and energy savings you're looking for – one of our Anglian designers will visit you at home to give expert advice based on your particular needs. They’ll show you the benefits of installing A-rated or Safe & Sound glass and guide you through the choice of decorative bars and glass that’ll give your home the style you’re looking for.

Once you've decided what you want, they will provide you with an accurate quote. Our craftsmen will make your sash windows to your home’s exact specifications, ensuring that they fit perfectly.
