Why Choose uPVC Windows?

  1. The most energy-efficient by design

    Save money on your heating bills with double and triple glazing uPVC windows that minimise the heat escaping from your home. Made from Anglian’s unique uPVC formula, your new windows retain the heat better in winter and reflect more heat in the summer.

  2. More window for your money

    uPVC is popular choice because it is both secure and stylish. The huge range of configurations makes uPVC windows perfect for both whole house replacements and single window upgrades.

  3. Ideal for noisy areas

    If you live on a flight path or near a busy road, uPVC windows with Anglian’s Safe & Sound double glazing offer 39db sound protection, higher than the standard 33db protection.  

  4. Secured by Design accredited

    Anglian's modern uPVC windows are accredited by this police initiative to help 'design out' crime through innovative window security. Our window frames have multipoint locking while the window glass is beaded from the inside so it can't be removed from the outside.

  5. Designed to be low maintenance

    Our uPVC windows are easy to clean, weather-resistant and won't ever rust, rot or flake. There is no need to treat, oil or paint your uPVC windows after installation. Simply wipe with a cloth and clean, soapy water.

uPVC Window FAQs

How much do uPVC windows cost?

Depending on the colour and glazing you choose, uPVC windows tend to cost less than window frames made of wood or aluminium. Modern uPVC windows offer an excellent balance of security, durability and quality for your money. If you need new window frames, uPVC windows are among the most affordable options on the market.

How long do uPVC windows last on average?
Depending on the quality of the window, uPVC windows can last anywhere from 20 years upwards. Anglian White Knight uPVC windows in casement and tilt and turn styles hold the BBA accreditation, which means they can last more than 35 years.
What is best for cleaning uPVC windows?
It is best to clean your uPVC windows with a sponge and warm soapy water. Washing up liquid is ideal for this. Read our complete guide for cleaning uPVC windows for more information, or visit our online shop where you can find our uPVC Window clearing kit.
What colours do uPVC windows come in?
uPVC windows come in a wide variety of colours that complement the interior and exterior of your home. The options include dual-colour, where the inside is finished in white and the outside is coloured. The most popular uPVC window colours are Anthracite Grey, Sage Green, White Knight, Dark Woodgrain, Golden Oak, Cream and White Woodgrain all of which are available from Anglian.
What is the difference between PVC and uPVC windows?
The main difference between PVC and uPVC is that PVC contains two plasticizers, BPA and phthalates, which makes the plastic much more flexible. In contrast, the 'u' in uPVC means it is unplasticized and does not have these extra materials added. The removal of these plasticizer makes it much stronger and far more suited to uPVC windows and door manufacturing.
What is better aluminium or uPVC frames?
While modern uPVC windows are considered ideal for whole-home renovations on a budget, aluminium windows are chosen for their slim frames and big range of colours. Both materials have high energy ratings and offer a high level of security and durability. Talk to our team today to find out more about the differences and decide which is best for your home.
Can modern uPVC windows be fitted to existing wooden frames?

We do not recommend that you leave existing frames in place when fitting modern uPVC windows. We replace your existing window frames during the fitting process, regardless of your window frame material. Installing modern uPVC windows together with new frames ensures a perfect fit and maximum thermal efficiency.

Should I replace wooden windows with uPVC?
uPVC is an excellent option if you are looking to replace your existing wooden windows on a budget. Thermally-efficient, affordable and available in a wide selection of colours to suit your property, uPVC is a foolproof choice.
