What are energy ratings?
Window Energy Ratings (WER) are a guide to the energy performance of your windows.
The British Fenestration Ratings Council (BFRC) window energy rating scheme checks all the components to
ensure the final window achieves the energy efficient standard claimed. This means that you just need to
look for the A-G ratings and remember A+9 is best – the higher the energy rating, the more energy efficient
it is. Simple when explained, isn't it?
The latest Building Regulations require all new homes to have a minimum ‘C’ WER rating. This is a useful
benchmark to consider when choosing replacement windows.
Windows from SmartFrames (Eurocell) have an energy rating of beyond A
A+9 the highest ratings possible.
This is because our windows feature an advanced six-chamber outer frame and PVC-U Thermal Inserts for
‘A’-rated thermal efficiency. In other words, our frames are used to create the most energy-efficient PVC-U
double-glazed windows available in the UK.
You can also be sure that our manufacturing methods are sustainable. We use 100% recycled material in our
PVC-U Thermal Inserts. Plus all our components are manufactured to the ISO14001 environmental
The benefits of A rated double glazing:
- Reduced energy bills: energy efficient glazing could save you around £130 per year on your energy bills.
- A warmer, more comfortable home: energy efficient glazing reduces heat loss through windows and means fewer draughts and cold spots
- A contribution to the environment: by using less fuel, you’ll generate less carbon dioxide (CO2) that leads to global warming
- Peace and quiet: as well as keeping the heat in, energy efficient windows insulate your home better against unwanted outside noise.
Energy efficient windows, when installed properly, can pay for themselves in lower heating and cooling costs
over a period of years. Taken together with improved comfort and appearance, high performance windows
from Eurocell are one investment every home can benefit from.
