Timber casement windows for listed buildings.
Replacement timber casement windows for listed buildings and conservation areas.
The Sash Window Workshop's casement windows have been designed to improve the energy efficiency of casement windows in listed buildings, while retaining their traditional beauty.
The windows replicate as closely as possible the proportions and designs of traditional timber casement windows, whilst incorporating the latest manufacturing techniques to use slim double glazing (or single glazing when this isn't approved).
