    We manufacture all our own glazing units to ensure maximum thermal insulation and acoustic properties, utilising double glazed safety glass as standard. In fact, we were the first to develop and patent double glazed sash windows.

    We can also tailor the glazing to your exact requirements – incorporating other glazing styles and specifications such as toughened and laminated glass, acoustic glass, and textured, obscured or stained glass.


    All of our traditional timber windows feature authentic mouldings that will perfectly complement your property. Our bespoke internal mouldings are created to match the original mouldings in your home, while outside detailing such as glazing bars and horns are matched to existing features.

    We can also finish our windows in your preferred colour. Just quote us your chosen paint and reference and we will make an exterior quality paint to match.


    For the perfect finishing touch, hardware, including handles and hinges, can be supplied in antique brass, chrome, satin chrome, black and pewter. Bespoke fittings can also be arranged on individual specification.

    Our industry-leading sash window frames come with a life time guarantee insured by the Independent Warranty Association (and all glazing units come with a 10-year guarantee). We want you to be as confident in your new windows as we are.

    Enhanced energy efficiency

    Your double-glazed sash windows will be flush-sealed and Argon-filled to maximise insulation and sound-proofing, so you can reduce your energy bills without compromising on authenticity.

    Individual details as you require

    If you want to finish your sash window in a certain colour, add some stained glass or even upgrade to curved glazing, we can accommodate your individual needs to match your home perfectly.
