This may mean replacing old glazing units, repairing existing window repairs cambridge rebates or putting in new cills that allow for better air sealing.

The deterioration of paintwork is a major problem with traditional windows. This is particularly true when sash windows are involved as the gaps between sashes can be extremely wide. In these instances water can enter the paint film and cause rotting to the wood or putty underneath. The rotting can be exacerbated due to weather conditions that are poor.

Glass became cheaper and more abundant during the late medieval period and into the 17th century. As a result, the glazed openings in timber-framed homes became more complicated with moulded mullions, wooden tracery and deep cills projecting into the air. Increasingly, the glazing was placed within frames with rebates and then pinned by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not only less prone to leaks but also allows for more expansive and clearer sheets of glass to be used in the windows than would otherwise be possible without the need for lead lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness and multilayer construction, as well as their care for detail. They also have large glass areas and deep projecting cills that reduce air infiltration. Windows can be designed to improve their energy efficiency by draught-proofing and secondary double glazing near me.
