British Fenestration Rating Council (BRFC)
The UK’s nationally recognised scheme for measuring window energy efficiency. Using a rainbow label scheme similar to that found on fridges, freezers and washing machines helps to simplify the method used in comparing the energy efficiency rating.
Reducing your Carbon Footprint
Having uPVC windows installed within your home will reduce the amount of energy you use. By consuming less energy to heat up your home, you will also be reducing your CO2 emissions. We use environmentally friendly manufacturing processes and recycle old products when completing an installation.
