Durability

Timber windows were built to last for centuries. However, they do need to be maintained to keep them looking good and operating properly. The most frequently-asked maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. The demand for enhancing timber windows in order to improve energy efficiency is also growing. This could mean replacing old glass units, repairing the window rebates that are in place, or installing new cills that allow for improved 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 the sashes can be extremely wide. In these instances water can enter the paint film and cause rotting of the putty or wood beneath. The weather can be a factor in accelerating the decay. To prevent this from happening, windows must be regularly painted with an exterior wood paint.

In addition to repainting, corroded areas need to be repaired with a resin-based repair product. This will ensure the maximum amount of original fabric is retained. It is also essential to reduce the number of holes drilled into the frame for cable entry, as they could let in water and cause decay.

Another major issue with older windows is the structural movement within the wall, which can cause deformation of the frame and the sash. This could result in sash no longer fitting correctly, sticking or jamming in the opening and cracked glazing. This can be corrected often by putting in new sash frames made of slow-grown deal (pine), or oak. The cill should be made from durable hardwood such as oak to prevent movement between the old and new work.

To reduce the risk There are a number of companies who produce Boston pattern sash made of wood that will fit most existing openings. These sash are available in a variety of sizes and finishes to meet the needs of the modern homeowner. These new sash, when combined with quadruple draft strips and a better thermal insulation, can significantly improve the efficiency of your home's energy usage.

Aesthetics

A lot of old timber frames have a great aesthetic appeal because they display, in a certain form, the materials technology, the construction process, and the architectural taste from the time period they were made. They could also have a significant historic value in their own right. This is especially true of early unglazed window openings in timber-framed structures, which were just a collection of openings within the frame, which were divided horizontally into mullions and vertical iron or wood bars to deter intruders.

It is essential to preserve the appearance of traditional timber window joinery. It is essential that any decay that results from the penetration of moisture should be immediately stopped once it is recognised. This is best accomplished by painting thoroughly, especially in areas where there has already been damage or degradation. It is advisable to use paints designed to be used as part of the system (primer as well as undercoat, finish and primer) and to follow the manufacturer's recommendations in terms of preparation and number of coats needed at each stage.

Wet rot is a common issue in older timber windows. The best way to stop it growing is to eliminate any damaged or rotten parts immediately to stop the spread of the fungus responsible for it. The replacement of rotting timber should be done with care and by using a slow-growing deal (pine) and, wherever feasible, the same species as which is being removed in order to prevent shifting between the new section and the 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 complicated with moulded mullions, tracery made of wood and cills that protruded deep. In recent years, glass was fixed into rebated frames with glazing sprigs, not lead cames. This method of glazing not only makes the windows less likely to leak and also allows larger sheets of glass to be used than would have been possible without the use of led lights.

Energy efficiency

Traditional timber windows are energy efficient because of their thickness, multilayer construction and attention to the smallest of details. They also have large glass areas and deep projection cills which reduce air infiltration. The windows can be made to improve their energy efficiency through draughtproofing and secondary glazing. However it is crucial to keep in mind that any such measures must be considered in terms of the overall appearance and integrity of the original window.

It is sensible to fix or upgrade historic windows rather than replace them, particularly when improvement in thermal efficiency can be made through simple repairs. The windows that are historic have a lot of historical significance, since they reflect a variety of technical development and changes to architectural taste. The pressure to replace these windows are usually based on the assumption that windows of the past will require replacement in the near future, however they are in a position to last for 150, 200 and even 250 years if properly maintained.

A good paint will stop moisture from entering the paint. It is also necessary to keep the paintwork in good condition to avoid mould and condensation. Modern synthetic paints can be problematic because they are usually made to be water-resistant and this may cause the growth of mildew in the window frame.

The majority of older windows were constructed from sapwood-rich wood. These timbers can deteriorate quickly when exposed to rain, however they can be protected by an extensive preservation treatment prior to use. It is essential to select the appropriate type of wood for the site and climate, as these factors will affect the durability of the joinery. Local upvc window and door repairs manufacturers have various types of sash timbers that can be adapted to fit historical openings.
