A-Rated Energy Saving Windows

Rising energy costs are a significant concern for both home owners and occupiers. Purchasers are increasingly looking at the total lifecycle cost, and specifying energy efficiency when procuring building products.

With the recent introduction of initiatives such as Home Information Packs, and the Decent Home Standard for local authority/housing association dwellings, the ability to prove your windows are energy efficient is an important aspect of improving the energy rating of a dwelling - which will make it more saleable. However, the main benefit of installing energy efficient windows is the ability to maintain a comfortable environment, with lower energy usage.

The BFRC Window Energy Rating scheme provides a straightforward method to demonstrate the energy performance of the window. Taking into account heat loss from the window through thermal transmittance (U Value) and air leakage, together with heat gained from the sun (Solar gain), the scheme gives A to G ratings for windows in a clear format. The energy rating system is already well recognised by customers, as it is widely used on white goods and other energy efficient products.

What is the BFRC Rating System?

The BFRC (British Fenestration Rating Council) rating system is a benchmark for comparing the energy efficiency of different window systems. The energy efficiency of a window is calculated using a standard window, 1230mm x 1480mm, with a fixed light next to an opening casement or sash. The BFRC rating equation includes three variable elements shown opposite.
