A-Rated Double Glazed WIndows


Helping you to choose efficient windows

When purchasing the latest energy rated double glazing windows it is best to make the most informative choice possible, to this end you will find some helpful information and facts that will assist you in making the right choice when committing yourself to a company and its windows.

energy efficient windows The UK’s national rating system covers Window Energy Ratings (W.E.R) from A to E, which was first Implemented in April 2006 by the British Fenestration Registration Council (B.F.R.C) with the British Standards Institute (B.S.I) offering a similar rating system soon after.
Consumers are used to the A to E ratings system to select white goods such as common kitchen machinery e.g fridges and freezers, so the W.E.R is an easy to understand and highly recognisable label. The WER's Scheme shows consumers the positive environmental impact that double-glazed windows can have on their property and gives the customer an easy way to compare products on quantifiable benefits.

What are U Values?

U Values are the thermal insulation properties of a product noted as W/m2K, Glass itself is not energy rated this is only done with the frame as the energy rating takes into account the Sealed unit insulation value (U) Air Leakage (AL) and Solar heat Gain (G Value) .

Legal Requirements of Glazing

Document L1B came into force in October 2010 and defined the minimum legal requirement of Windows to be 1.6W/m2K (U Value) or a W.E.R of C or Better and Doors to be 1.8W/m2K or better. Where frames cannot be changed due to conservation reasons a Sealed unit with a Centre Pane U Value of 1.2W/m2K should be used.
