Timber Box Sash Windows in Oxford

Windmill Window’s timber box sash windows are of the same exceptional quality as the rest of our timber product, offering the same range of timber as with all our timber products including hardwood, softwood and Accoya.

We aim to replace sash windows with aesthetics just like the originals but with 21st century standards of security and thermal efficiency. By combining the latest technology with authentic traditional aesthetics, our box sash windows do not disappoint. Sophisticated spring and spiral balances replace the pulley weights but for those who prefer 100% traditional features then pulley weights may still be used as well as a full array of traditional furniture.

With all sash window installations, colour matched timber architraves, linings and internal window boards are supplied and installed as required to achieve the high quality internal finish as well as external.



  • All furniture is offered in traditional brass, as shown below, or chrome.
