The Window Energy Rating (WER) should let you know the energy efficiency of that particular window. You may have noticed energy ratings on your white goods, which use a A+ – G scale. You’ll find them on fridges, freezers and washing machines.
A+ rated windows are the most energy efficient you can get. All new and replacement windows must have a minimum Window Energy Rating of C or higher.
Working with the insulating properties of the double glazed or triple glazed unit our A+ Plus Windows bring together a window frame with five insulating chambers, and a sash frame with an impressive six insulating chambers and a bubble gasket which performs in much the same way, and is just as important, as the seal on your fridge freezer.
