If so, the wood will need to be replaced. The new wood is then inserted into the areas that are rotten and primed and painted.

Another way to enhance the acoustic properties of the window is to make it draught-proofed. To reduce the amount air that flows between the glass panes heavy gases are infiltrated into the gaps.

All of these parts must work seamlessly together, demanding millimetre-precise gaps and an array of pulleys and weights that are concealed in the frame.

When historic double glazed windows repairs are reglazed using insulated glass units, the original stiles and rails often get cut out to accommodate the greater thickness of the new glass.
