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

  • Fills your room with light and a feeling of space
  • Complements the other windows in your home
  • Choice of shapes, including splay, square, circular or single-ended
  • Energy efficient, and can help reduce your heating bills
  • Secure with shoot-bolt locks, key locking handles and toughened glass

Our uPVC bay windows not only offer more light and a feeling of space, they also add a stylish and beautiful feature point to any room. Our bay windows match all of our window styles so the choice and variety is enormous.

Bay windows can help you achieve the cost and energy savings you’re looking for and are effective at noise reduction – great for dampening external sounds. They can also provide added heat retention – our option of triple glazing will give you an extra layer of warmth.

One of our Anglian designers will visit you at home to give you expert advice tailored to your specific circumstances. They’ll show you the benefits of opting for our A-rated windows or triple glazing, guide you through the choice of frame configurations that will make your bay window design just right for each room, and show you our range of hinges, openings, handles, decorative bars and glass.

Once you’ve decided exactly what you want, they can give you an accurate quote. Our craftsmen will then make your windows to your specifications, ensuring that they fit perfectly in your home.

Glass options
We make every glass panel uniquely for your windows and offer you an exciting choice of clear, obscure, etched and leaded glass, as well as decorative designs and bars. Your Anglian designer can help you choose the right glass for each window during your appointment.
Glazing Options
  • Double Glazing
  • Triple Glazing
    Our new triple glazed windows are designed and manufactured to keep in more of the sun's heat and retain more warmth within your home. The extra panel also offers great acoustic performance reducing noise from the outside. More about triple 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.
Performance / Energy Rating 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
  • A
  • B

Our uPVC bay windows will add distinctive style to your home. Manufactured using our own uPVC formula, they’re strong, secure and won’t fade. The choice of energy-efficient double or triple glazing will help keep your home warm and cut your heating bills. You can also opt for sound-reducing windows to dramatically reduce outside noise. To complete the transformation, there’s a wide range of configurations, colours, finishes and handles to choose from, and you can opt for plain or decorative glass.
