The most common maintenance tasks include repairs to sash cords and re-tightening the sash pulleys and painting. There is also a rising demand to upgrade timber windows to improve energy efficiency. This may mean replacing old glazing units, fixing the window rebates that are in place or putting in new cills the air to seal better.

The deterioration of paintwork is a major issue with traditional windows. This is especially important where windows made of sash are involved because the gaps between sashes can be quite large.

Glass became less expensive and more abundant during the late medieval period and into the 17th century. In the process, glazed openings on timber-framed houses were more elaborate, with moulded mullions and traceries, made of wood and deep projecting cills.

This method of glazing not only makes the windows less likely to leak and Full Article break, but also allows more clear glass sheets to be employed than would be possible otherwise without the use of leaded lights.

Energy efficiency

Traditional timber windows provide a good energy performance due to their thickness and multi-layer construction. They also pay meticulous attention to detail. The large glass areas, deep projecting cills, and the large glazing areas minimize air infiltration. With secondary glazing and draughtproofing, windows can be upgraded to increase their energy efficiency. It is crucial to keep in mind that these measures should be taken into consideration in relation to the overall integrity and look of the original windows.

So, retaining existing historic windows that are in need of repair rather than replacing them makes sense, particularly when their thermal enhancements can be achieved cost-effectively through simple repairs and improvements.
