YORKSHIRE SLIDING SASH WINDOWS, YORK
This lovely house is Grade II listed, and is believed to date back to the reign of Charles 1st - early 17th Century.
We supplied and installed Yorkshire sliding sash windows (horizontal sliding sashes in a deep frame) and flush casement windows to replace a mixture of old Yorkshire Sliders and 1970’s casement windows.
The location is Great Ouseburn - between York, Harrogate and Thirsk. Listed Building Consent was required in order to proceed with window replacement and was granted because we were able to meet the strict specification criteria.
We were allowed to use special slim double-glazed units ('Heritage glazing') with a 6mm gap between the panes and the narrow timber glazing bars had to be solid 'through-bars' instead of the usual bonded bars. Every pane of glass is a separate glazing unit held in with butyl-based putty and over-painted to match the timber.
