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

Our unique collection of sash windows faithfully replicates these timeless designs down to the finest details and includes the slimmest traditional box sash available in the UK.

Glorious to behold, easy to slide and constructed to deliver the highest insulation standards, security and longevity, our Sash Windows are available with traditional chains, cords or a hidden spring mechanism.
