A Rated Double Glazing

The benefits of A-rated double glazing are clear. Investing in A-rated double glazing will enhance your home by making it warmer, less draughty and ultimately, more comfortable to live in.

If you are currently looking for a company to install A-rated windows for you then there’s a couple of things you need to be aware of. It may come as a huge surprise but not all companies that say they fit A-rated windows are not actually fitting A-rated windows!

The ‘rainbow’ label which everybody is familiar with states which energy efficiency band a window falls into. If you take a look around at double glazing company’s web-sites or adverts in newspapers you’ll notice that there are A-rated window labels on display pretty much everywhere you look. To the consumer – the presence of an A-rated label means that the window being installed is guaranteed to be A-rated right? Wrong!

Unfortunately it is true that some companies display an A-rated label but actually fit a window which is anything but. The problem is that it is virtually impossible to distinguish an A-rated window from an inferior window just by looking at it. The fact is that they do look very similar, a large part of the difference between products is the specification of the coating on the glass – which is impossible to see because it is invisible.

So the question is – how can you tell if the company you are dealing with are installing an A-rated window or not?

The answer fortunately is simple. If the company is a manufacturer (i.e. they make windows in their own factory and install them – they should be able to give you a certificate to prove how the A-rated label declaration has been achieved. In order to receive a license to use an A-rated label a manufacturer must have test evidence to prove that all the components of their window come together in a sufficient way to make the window an A-rated specification as defined by the BFRC (British Fenestration Ratings Council). A simulation must be undertaken by an independent UKAS accredited test house and a certificate produced to prove the results. This simulation takes into account the quality of the draught-excluding gaskets, the specification of the glass sealed units, the insulating properties of the chambers inside the UPVC, the thickness of the steel reinforcement to name just a few of the factors that have to be considered.

The presence of a BFRC certificate from a UKAS accredited test house is only the first step. This certificate proves that the company is capable of making one A-rated window. The re-assurance that you will need as a homeowner is ‘how do I know that this company will make an A-rated window every time and especially the time they are making windows for MY house?’

Again, the answer is simple. Any UPVC double glazing company worth its salt should be able to provide further evidence to prove that they have been audited by a separate UKAS accredited test house which audits the company to prove that it has good systems in place to guarantee that all windows made and fitted by them are worthy of the A-rated label – not just the first one submitted to gain the BFRC certificate!
