    Add style and energy efficiency with bespoke windows

    Our bespoke windows may look different from the conventional, but their energy efficiency capacity is equally just as high. Like all our window options, our bespoke 'A' energy rated windows will help to boost your home’s thermal performance, saving you money on your heating bills whilst improving your standard of living.

    Whichever window material you opt for, you can be sure that they’re fitted with a number of advanced features to heighten its thermal performance. This includes warm edge spacer bars, high-tech glazing and intricately beaded frames.

    Our custom-made windows can be fitted with either our double glazing or comfort glass and can achieve very low U-values. Double glazed tailor made windows use two panes of glass that encompass an argon gas filled chamber. This specification is able to break up the airflow so the warmth is kept inside and the draughts kept out. For homeowners looking for even further energy efficiency, our comfort glass window options includes an additional pane of glass. With 5x better thermal capabilities than a standard glazed windows, it’s the ideal solution for properties exposed to tough weather conditions or in noisy areas.
