For almost half a century, we’ve been developing and installing double glazing in houses across the UK, helping to make homes warmer and more secure. Whether you’re replacing original windows in an older property or trying to reduce your heating bills with energy-efficient glazing, we’ve got a window that’s right for your home.
Our double-glazed windows will not only make your home feel cosier, but they’ll also give it a facelift and transform the look of the property immediately. Each of our double-glazed windows is A-rated as standard and feature two equal 4mm glass panes separated by a 16mm cavity. This helps to achieve excellent heat retention and deliver a high level of 31dB sound insulation to help dampen outside noise. We also offer further sound-reducing window options.
Double-glazed windows from Anglian are incredibly customisable and are available in a choice of materials, styles and colours. Regardless of which product you choose, all of our frames are incredibly energy efficient, with a minimum B-energy rating, surpassing the Building Regulations’ requirement of a C rating. Most of our double glazing achieves an A rating as standard, though A+ rated windows are also available. This means your home could actually gain more "free" heat than it loses, resulting in much lower heating bills. If you're looking for A++ performance, our triple-glazed windows offer even higher levels of performance.
