Energy Ratings & U Values
Duraflex product performance
All windows now have to comply with energy ratings. As a result an independent body, BFRC (British Fenestration Rating Council) provide a label system that enable consumers to understand any products energy performance.
The BFRC label clearly indicates the rating of the designated window (A++ to G) depending on the energy efficiency levels achieved by the manufacturer. A++ is the most energy efficient, G the least efficient. The level of energy efficiency is indicated by one of a range of coloured bars – very similar to the energy efficiency labels found on fridges, freezers, washing machines and other household product’s.
During the rating process the energy efficiency level is calculated and verified by BFRC, which is totally independent from any manufacturing or installing company. Manufacturers of BFRC rated product and BFRC Authorised Installers are audited to ensure that their energy efficient windows are achieving the stated rating. The BFRC energy ratings allow you to compare varying window products and choose the most suitable for your home.
