Sash windows suit period properties - Georgian, Victorian and Edwardian houses in particular - where a casement would look wrong. Modern double-glazed sashes replicate the classic vertical-sliding design while cutting heat loss by 60-70% versus single-glazed originals.

You have two real choices: a full replacement in uPVC or timber, or a sympathetic refurbishment where the original box and sashes are kept but slim-profile double glazing is fitted into the existing frames. Refurbishment is often the only route in listed buildings or strict conservation areas, and typically costs 30-50% more than a like-for-like uPVC replacement.

Popular specs for sash windows

Vertical sliding, spiral balance or traditional cords-and-weights, slim-profile 14mm or standard 28mm sealed unit, run-through horns for authenticity, factory-finished timber or foiled uPVC in Chartwell Green, Anthracite Grey or white woodgrain.
