However, you may be wondering what energy efficient windows are and how they work. In response to this we’ve tried to provide you with a small guide to energy efficient windows:

How can I measure the energy efficiency of my windows?
The level of insulation offered by any given window is calculated from a combination of the insulation of the frame and that of the glass used. Other factors include frame size and air leakage, which also taken in to consideration, making it quite a difficult calculation to understand.

This has lead to the government introducing the Window Energy Ratings scheme. By using the same rating system that is used for white goods, such as fridges and washing machines, it is now possible to rate windows from any given supplier. The finished window is independently tested and awarded a rating from A to G.

Those achieving a C-rating or above demonstrate they have been designed, manufactured and tested to provide a good level of overall thermal efficiency.

So what is the difference between C-Rated and A-Rated?
An A-rated ThemaglassMAX window will not lose any heat whatsoever from your home. The design is obviously a little more complex than that, but the principle is true.
By installing energy rated windows you will be helping to improve the overall performance of your home, which will not only reduce your heating bills and CO2 emissions, but it could also help improve the value of your property as well.
