Energy Efficient Windows

The windows that we select for our homes bring light, warmth and beautyinto them. Poorly selected windows are a major source of heat loss in the winter and can reduce comfort and the amount of effective living space. Energy efficient windows, when correctly selected and installed, will help to minimise the heating and lighting costs and will ncrease comfort and the amount of useable living space


Save Money by selecting Energy Efficient windows
which reduce your heating bill.


Energy Rated Windows

The British Fenestration Rating Council (BFRC) an independent body that monitors and controls Energy Efficient Window ratings have developed a Energy Window rating system which allows the consumer to rapidly compare the Energy Efficiency of different window products.


The familiar A to G rating labels where A is a more Energy Efficient than a G rated window means that the consumer can easily and quickly choose the most suitable window for their needs. The BFRC rating simply and effectively assesses the Energy performance of the whole window and takes into account frame material, frame design, glass type, air leakage and all the other components that make up the window. For the first time it is possible to compare the Energy performances of different complete windows simply and quickly.




Saving Money

Energy efficient windows may cost more initially but will not only improve comfort but will save energy and money for the life of the window. Over the life of a window the cost of heat loss is greater than the purchase cost. Choosing the most Energy efficient window will save money.

Choosing windows

The BFRC rating makes selecting windows for Energy efficiency simple. It allows windows to be easily compared to find the most Energy efficient product.
