Energy Ratings

Window Energy Ratings are something you should be looking out for when considering new double glazing. Introduced in 2004 by the British Fenestration Rating Council (BFRC) it has been designed to keep the method of measuring the level of energy efficiency as easy as possible.

The use of a simple lettering system from A (the best) to G (the worst) you can see exactly how efficient your new double glazing will be. The lower the WER, G for example, the more heat will be lost. Ultimately A rated windows will therefore save you money in the long run on heating bills, locking the warm air inside your property.


Here at Art On Glass we are proud to say that our energy efficient uPVC windows are all BFRC approved. Our Liniar windows are capable of achieving an A+12 energy rating, one of the highest available to date.


Recommended by the Energy Saving Trust

Our windows are all endorsed by the Energy Saving Trust and will display the ‘Energy Saving Recommended’ logo. This way you know you’re getting the very highest energy efficiency.

Reduce Your Heating Bills

Keep your heating bills as low as possible with the installation of energy efficient double glazing. With an A+12 WER you can retain an additional 12 kWh per m²  per year over a standard A+0 rated window.

Reduce Heating Bills

Committed To Recycling

Each of our double glazed products are fully recyclable. Never containing steel reinforcements, our advanced uPVC design is what makes our windows just as robust and strong as reinforced windows but with Eco friendly components.


Reduce Your Carbon Footprint

You will significantly be reducing your carbon footprint when choosing to have our uPVC windows, doors and conservatories installed. Your property will reduce the amount of CO2 you produce by around 2/3 of a tonne each year.


100% Lead-Free

An Art On Glass double glazing installation is 100% lead free. We all know the problems lead can cause to the environment which is why we are consciously installing lead-free products throughout Cambridgeshire.
