Energy efficiency

Cheaper bills and better for the environment

Our timber windows won’t just reduce your heating costs; they also meet new energy efficiency guidelines contributing to environmental measures for our planet. If you start with the rooms that it costs you the most to heat you could begin to save money instantly. Energy saving double-glazing can cut heat lost through windows by half, and save you £100's a year on your heating bills and around 720kg of carbon dioxide (CO2).

Our high performing timber windows
All of the timber windows that we supply are energy rated at 'C' and above. At a rating of 'C' our timber windows are at very high standard of quality, in terms of noise reduction, security and heat retention. We can also supply and install “B’ and ‘A’ rated windows for further enhancements – but you can be assured that even at ‘C’ rating your windows are of an exceptional standard and for most of clients that has more than met their requirements. And, as an approved partner installer of George Barnsdale we are able to provide test data from third party, accredited test houses to back up our claims.

The Energy Efficient Window Ratings Label
The BFRC (British Fenestration Rating Council) scheme is the UK’s national system for rating the energy efficiency of windows and is recognised by the Building Regulations for replacement window installations. Window Energy Ratings use a consumer-friendly traffic-light style A-E ratings guide similar to that used on ‘white’ goods (such as fridges and freezers). This ratings label can help you to make more informed choices about the energy efficiency of the windows you are thinking of buying.

Each window rated by the BFRC has a unique label displaying the following information:

  • The rating level - A, B, C, etc...
  • The energy rating eg. -3kWh/(m2.K) in this example the product will lose 3 kilowatt hours per square metre per year
  • The window U value eg. 1.4W/(m2.K)
  • The effective heat loss due to air penetration as L eg. 0.01 W/(m2.K)
  • The solar heat gain eg. g=0.43
  • This tells you how well your windows will do at:
  • Helping you contain and conserve heat within your building in the winter
  • Keeping out the wind
  • Resisting condensation
  • Contributing to improved sound insulation
