    Live comfortably while saving money

    The price of windows should not be considered alone. Every style and material offers differing levels of heat retention – meaning that the right choice could go on saving you money far into the future. Our highest-rated double and triple glazing products really are the highest rated: there’s no higher grade on the WER (Window Energy Rating).

    We’ve achieved this via a number of top-range technologies and features including multi-chambered window profiles, argon-filled inter-pane areas, low-e glass, specially treated to reflect heat back into a room, and the newly patented Warm Edge Spacer Bar.

    Sleep safe and sound

    Being burglar-proof is a must for any reputable window company – because it’s a must for every customer. 

    You may live in a low-crime area – but it never hurts to build the best as standard. Those with additional concerns can explore our range of locking mechanisms and find out what other specifications influence security.

    Keep your quiet nights quiet

    The same high standards which will keep your home warm and safe will also keep it quiet. In part, noise cancellation is a bi-product of good heat retention. Warm Edge Spacers Bars, multi-chambered profiles and argon-filled inter-panes all dampen noise in both our double and triple glazed windows.

    The other half of the equation is good workmanship: how snugly seals, panes and frames are fitted. Installers who aren’t skilled and experienced may make mistakes during installation or while pre-measuring, both leading to gaps through which heat and noise may pass. We, on the other hand, have 50 years’ experience of building a great reputation by hiring and training the best people.

    Double or triple glazed windows?

    Both double and triple glazing provide additional home security, enhance energy efficiency and reduce noise pollution. But which is best for your home’s replacement windows?

    Double glazing is made from two high-performance panes of glass with a layer of argon gas between that is sealed with a warm edge spacer bar. Triple glazing incorporates an additional panel of glass with two argon gas filled layers, meaning it’s up to five times more effective than single glazed windows.

    All of our windows are A-rated for their thermal efficiency, meaning they will keep the cold from entering your home. So, choosing between double and triple glazing really depends on your home’s needs. The utilisation of modern manufacturing in our high-quality double glazing provides a comfortable temperature for your home all year round. Our triple glazing boasts the lowest u-value of any glazing type, offering unparalleled levels of noise reduction, making it ideal for homes in particularly busy areas.
