uPVC Sliding Sash Windows

Each uPVC sash window is individually-made with your choice of frame, glass and configuration.

  • Give your home traditional charm with 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 drowning out external sounds

Our sliding sash windows' energy-efficient construction comes with B-rated glass as standard to help reduce your heating bills and keep your home warm when it's cold outside. We can even make them tilt so cleaning is easy.

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 and show you the benefits of upgrading to A-rated glass or installing Safe & Sound glass. They'll also guide you through deciding on decorative bars and glass to give your home the style you’re looking for.

Once you've decided what you want, they can give you an accurate quote. Our craftsmen will make your sash windows to your exact specifications, ensuring that they fit perfectly.

Glazing Options
  • Double Glazing
  • Safe & Sound
    Anglian's standard A rated windows provide an ideal level of sound reduction at 31dB but if you need even higher levels of sound insulation you can opt for our Safe & Sound glazing which uses 6.4mm laminated glass on the outside and a 4mm inner pane, with a 14mm cavity, increasing the sound insulation to 36dB. That's a 16% improvement. More about Safe & Sound.
Energy rating/performance options
These tell you how much energy a window loses or gains. They’re based on three factors – how much heat is retained or lost through the window, how much heat can be harvested from the sun and how much heat is lost through draughts. More about energy ratings
