Traditional charm & modern performance for homes in Leeds

Featuring two vertically-sliding sashes that slide smoothly to open and close, these elegantly designed windows are perfect for Victorian properties and other period houses. Thanks to their modern uPVC construction and the latest glazing technology, each of our sliding sash windows are wonderfully efficient. This means they’re great for saving energy and retaining heat in your home.

The beauty of uPVC is that it will not rot or warp as time goes on, and nor does it require retreating. Timber, however, needs retreating in order to stop it from experiencing both issues, which means that uPVC sliding sash windows have a number of valuable advantages over the timber equivalent.

    Glazing

    Great glazing options to suit every homeowner

    With a number of decorative glass options to choose from, you can add another stylish element to our sliding sash windows and improve privacy levels. We can also fit them with Georgian or astragal bars, further enhancing their classic window charm.

    Choose from two leading uPVC sash window systems

    We install two distinctive, high-performance uPVC sliding sash window systems: ECOSlide and Genesis VS. Although both are equally excellent replications of traditional sash windows, those who are looking for high-end, authentic sash windows should consider opting for the Genesis VS.

    The Genesis VS system utilises mechanical joint methods. This gives their frames and window sashes seamless corner joints, just like those you’d find on traditional timber sash windows. The result of this is truly stunning sash windows that achieve maximum authenticity.
