Triple Glazing – the ultimate in energy efficiency and noise reduction

For exceptional energy performance from your home, triple glazing is the most efficient window choice
available offering truly significant fuel savings.

Triple Glazing – the facts:

  • Over 10 years, a typical home with typical glazing could save £7,000 and 47 tonnes of CO₂
  • 60% more efficient than standard ‘C’ rated* windows
  • 40% more efficient than ‘A’ rated* windows – the most energy efficient double glazed windows
  • Reduces condensation by up to 80% by minimising heat transfer around the window seal
  • First choice for excellent noise reduction  – even for under a flight path or the busiest of roads

As well as being the best option to reduce your carbon footprint and make your home more comfortable and secure, the construction of a triple glazed window can also give you a clearer view. The reflective spacers around the windows give a clear uncluttered design, whatever style of frame or finish you choose. Ask our design team for more information to see what investing in triple glazing would mean for your home.
