From 1st October 2010 we are going to be a guaranteed ‘C’ rating across all of our window and door styles. We will be using the methods suggested by Giles Wilson from Fensa to achieve this which include the fact that if using glass with a 1.2U centre pane Value will give a 1.6 U overall Window,using the very latest in technology of glass thus complying with a “C”minimum rating.
Beyond this, our most popular range, the Cottage Range, is going for the official WER (Window Energy Rating) and is already been simulated as an “A” rating. An independent audit of our systems inside the factory in regards to the WER energy ratings on our windows will take place and this extensive cross examination will cover aspects such as air leakages and solar gains as well as the U value of the glass.
This ‘A’ rating will match the government requirements for 2020 when all windows will match a zero carbon emissions target.
As an aside, once we have this classification for the Cottage window range we will also offer a service to our customers to enable them to up-specify any product in our range to this ‘A’ rated window glass specification but will not have the offical WER A Rating until a later date.
