Anyone looking to buy energy-efficient double glazed windows can now quickly and easily compare the ability of different windows to keep in the heat in their homes, by checking the window’s ‘U’ rating.
‘U’ ratings are used in all kinds of building components. They measure how effective that component, for example a window or roof, is at retaining heat.
The new law stipulates that all replacement UPVC double glazing windows must now meet three minimum standards for energy efficiency. The factors which govern this are the efficiency of the glass in the window itself, and that of the sealed units which encase them.
The rule to remember is that the lower the ‘U’ rating, the more efficient the window, and therefore the lower the heat loss.
In many cases, having a double-glazed window containing glass with a low ‘U’ rating installed will be at least as good as opting for a window fitted with triple glazing – but of course, the window units will be no heavier than those with standard double glazing.
“Looking out for the ‘U’ ratings when setting out to buy energy-saving windows is something that everyone should try to do,” said Les Yates of home improvement comparison website Local Quoter. “When anyone is looking to buy energy-efficient windows, it will be one of the key ways of distinguishing between the various window types available.
