Durability

Timber windows were built to last hundreds of years. They do require some maintenance to keep them looking great. The most frequently-asked maintenance tasks include sash-cord repairs, re-tightening sash pulleys, and painting. There is also a rising demand to upgrade the timber windows to increase energy efficiency. This can include replacing old glazing units, fixing existing window rebates or installing new cills for improved air seal.

They could have significant historical significance on their own. This is particularly true for early windows that were not double glazed door repairs in timber-framed buildings, in which the majority were simply a series of openings in frames of structural construction, which were divided horizontally by mullions with vertical iron or wood bars to keep out intruders.

It is advisable to use paints that are designed to be used as part of the system (primer, undercoat and finish) and follow the manufacturer's guidelines in terms of preparation and number of coats needed at each stage.

The fungus that causes wet rot is able to spread quickly in old windows made of timber. To prevent this, take out any damaged or rotten components as quickly as you can. The replacement of wood that is rotting must be done with care using slow grown deal (pine) and, whenever feasible it is the same species as that which is being removed in order to prevent differential movement between the new section and existing timbers.

Glass became more affordable and abundant in the late medieval era and into the 17th century. This led to glazed openings on timber-framed houses became more complex with moulded mullions and traceries, made of wood and cills that protruded deep. In recent times, glass was fixed into frames that were rebated with glazing sprigs instead of lead cames. This method of glazing not only makes windows less likely to leak and break, but also allows wider sheets of clearer glass to be employed than would be possible without the use of led lights.

Energy efficiency

Traditional timber windows are energy efficient because of their thickness and multilayer construction as well as focus on particulars. The large glass surfaces, the deep projection cills and wide glazing areas help to reduce air infiltration.
