Sash windows grace some of the most beautiful homes in the country and replacing these originals, when the time comes, is our speciality.

Our unique collection of timber sash windows faithfully replicate these timeless designs down to the finest details. From slim sash boxes, more traditional weights and pulleys mechanism to more specialised solutions for listed buildings and conservation areas, we can manufacture and tailor our bespoke sash windows to your requirements.

Our timber vertical sliding sash windows are manufactured to achieve superior insulation and high performance without compromising its classical appearance.

Designed with conservation and listed buildings in mind, this particular type of Heritage sliding sash features double glazing with the revolutionary, ultra-thin glazed unit with an outer panel of low-emissivity glass, an inner pane of clear float glass, and a vacuum rather than air or gas between the two panes of glass.

Thanks to the vacuum glazing technology this extremely thin glazing can be fitted in old style fine frames, maintaining the original appearance of older, traditional buildings whilst providing an excellent thermal insulation.
