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 building a new house or replacing original windows in an older property, we’ve got a window that’s right for your home.
Our double glazed windows will not only make your home feel cosier, they’ll also give it a facelift and transform the look of the property immediately. Each of our A rated as standard double glazed windows feature two equal 4mm glass panes, separated by a 16mm cavity, which achieve excellent heat retention and deliver a high level of 31dB sound insulation. We also offer further sound reducing window options.
Our replacement windows are available in a choice of materials and styles and regardless regardless of which product you choose, all of our frames are very 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 and A+ rated windows are also available, which means your home could actually gain more ‘free’ heat than it loses, resulting in much lower fuel bills. If you are looking for A++ performance, our Triple glazed windows offer even higher levels of performance.
