Energy Efficiency

Your home is in safe hands when you choose High Performance 'A' Rated windows from Bryant & Cairns.Not only will you benefit from real savings on your fuel bills, but you will also be helping reduce the impact on the World's natural resources.

Did you know that our homes account for a quarter of all CO2 emissions in the UK and windows can account for up to 30% of the total heat lost from a house? 'A' Rated windows can have a zero energy loss over a year cycle or even add energy back into the room via solar gain.

Many window companies lay claim to having 'A' Rated Windows when in fact all they offer is Low E glass or triple glazing, so it is important to check the credentials. The only way to check if a window is genuinely  Energy Rated is to check the British Fenestration Ratings Council website BFRC If it isn't registered… it isn't Energy Rated!

  • Highly Insulated PVCu frames provide a barrier to cut heat loss.
  • Heat from radiators is reflected back into the room, keeping more warmth inside your home.
  • Even during winter, energy from the sun passes through the specialised glazing and has a warming effect on the room.
