All replacement window installations are subject to Building Regulation requirements. The Window Energy Rating (WER) scheme is a recognised method of compliance. Windows are rated using the ‘rainbow’ scale with G (red) being the least energy efficient and A (green) indicating the most energy efficient windows.
WER rating for windows is determined by 3 factors:
- How much free heat and light is captured from the sun
- How well heat is retained and radiated back into a room
- Amount of heat lost due to draughts or cold spots
Mendip supply windows glazed with Planitherm glass, a high performance glazing system that is specifically designed to improve your home’s energy efficiency. All of our windows are A-rated as standard, meaning Mendip windows are highly effective at retaining heat whilst reducing draughts and cold spots, saving you money on your energy bills.
