Timber Sash Windows


Timber sash windows combine stunning period design with modern energy efficiency. Excellent heat saving, unrivalled soundproofing and high-security technology come as standard with our wooden windows.

Our timber sash windows are ideal for traditional properties that need replacement windows, as well as homes in conservation areas. Even if your home is not listed or in a protected area, sliding timber sash windows are guaranteed to add character to your property.

Our vast range of London-based customers swear by our top quality products and we maintain high standards for installation too. We ensure that our window units are installed to perfection so that they not only look good but maintain their excellent energy efficiency wherever they are fitted.

Our timber sash windows are built to the highest specifications and benefit from slim double glazing as well as a robust timber frame made from hardwood, softwood or high-performance Accoya.
