Energy Efficient

The benefits of energy efficient windows – Energy efficient glazing keeps your home warmer and quieter as well as reducing your energy bills, whether with double or triple-glazing, secondary glazing, or just heavier curtains.

Did you know that around 20% of heat escaping from a home is lost through its windows? Just imagine how much old, draughty windows might be adding to your heating costs. We understand that buying replacement windows for you home is a big investment, and that’s why it’s important to get it right. Energy efficient windows with double – or even triple glazing – will not only fill your home with natural light but keep your home secure and warm for years and years to come.

What are energy ratings?

Window Energy Ratings (WER) are a guide to the energy efficiency of your windows. The British Fenestration Ratings Council (BFRC) checks all the parts of the window and then grades its performance accordingly. The scale goes from A+ – G , with ‘A’ being the most efficient, and ‘G’ the least. The latest Building Regulations require all new homes to have windows with a minimum ‘C’ WER rating.

Enjoy the highest possible energy rating with Victoria Windows and Doors

Our double-glazed UPVC windows offer the highest level of energy efficiency available on the UK market – beyond A+. This is because they are made with an advanced six-chamber outer frame and UPVC Thermal Inserts. In simple terms, our frames are engineered to provide as much thermal insulation as possible, so our customers can reap the benefits. Our windows are sustainable too. We use 100% recycled material in our UPVC Thermal Inserts plus all our components are manufactured to the ISO14001 environmental performance standard.

Benefits of energy-efficient windows

  • Smaller energy bills.
  • Smaller carbon footprint.
  • More comfortable home: energy-efficient glazing reduces heat loss through windows and means fewer draughts and cold spots.
  • Peace and quiet: as well as keeping the heat in, energy efficient-windows insulate your home against external noise.
  • Reduced condensation: energy-efficient glazing reduces condensation build-up on the inside of windows.

The costs and savings for energy-efficient glazing will be different for each home and each window, depending on its size, material and the installer you choose. Double glazing should last for 20 years or more.
