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

With a wide selection of frame configurations and the option of a wood-effect, white, or our popular White Knight finish, your uPVC sash windows will make a stunning addition to your home. Touches such as decorative, etched or leaded glass, window bars and your choice of handles and hinges, complete the look. The latest security features will help to keep you safe, and you can select your preferred energy rating or sound reducing glass to reduce noise.

Be inspired by our customers who have transformed their homes

Upgrade & EnjoyModern technology suitable for period homes

Martin and Gill wanted to replace their windows with something more in keeping with 21st century standards, without destroying the integrity of their home and causing an outcry among their neighbours. They took their questions to the local planning authority, backed by a company with a reputation that spans nearly five decades.

“We moved into a conservation area,” explains Martin. “We had used Anglian before at our previous home and were very happy with their approach. The company talked to our local planning officers who were happy that our old draughty windows were going to be changed for highly energy efficient windows that looked like wood.”

“While the team of fitters were extracting some 1960s casement windows, they discovered some old sash boxes, so we had new sliding sash windows put in. It looks more like a restoration than a renovation.”

“I’ve been amazed at the change in temperature and the cold spots that have disappeared. I wouldn’t have believed the change it has made – it’s absolutely amazing!” says Martin.
