When repairs are feasible to windows that are already in use should be made in situ. The repair system that is based on resin can be used to fix the worst areas of decay without removing the whole window.

Durability

The timber windows in many old structures were designed to last for centuries. They do require some maintenance to keep them looking great. The most frequent maintenance tasks include repairs to sash cords, re-tightening sash pulleys, and painting. There is also a growing demand to upgrade the timber windows to improve energy efficiency. This can include replacing old glazing units, repairing existing window rebates, or installing new cills to increase the air seal.

The deterioration of paintwork is a major issue with traditional windows. This is especially important when sash windows are concerned, as the gaps between sashes can be quite large. In these cases water can enter the paint film and cause rotting to the putty or wood beneath. Poor weather conditions can exacerbate the decay. To prevent this cambridge windows, they should be painted regularly using an exterior wood paint that is suitable.

In addition to repainting, areas that have corroded need to be repaired with a resin-based repair product. This will ensure that the highest possible amount of the original fabric is retained. It is also essential to reduce the number of holes drilled into the frame for cable entry as these can admit water and lead to decay.

Another issue with older windows is structural movement in the wall that could cause deformation of the frame and sash. This can lead to the sash not fitting properly jamming, sticking or sagging in the opening, and broken glass. This is often corrected by fitting new frames for sash made of slow-grown deal (pine), or oak. The cill should be constructed of a strong hardwood such as oak, in order to prevent any the movement of new and older work.

There are a variety of companies that manufacture Boston pattern wooden sash to fit into the majority of existing openings. They are available in various sizes and finishes that meet the requirements of modern homeowners. Together with quadruple draught strips and a better thermal insulation, these sashes can make a an enormous difference to the energy efficiency of your home.

Aesthetics

Many old wooden windows have an excellent aesthetic value because they typically demonstrate, in a way the materials and technologies and architectural taste of the period from which they originate. They also may have significant historical value in their individual cases. This is particularly true for early windows that were not glazed in timber-framed buildings, where the majority of them were series openings in structural frames that were subdivided horizontally by mullions, and vertically by iron or wood bars to protect against invaders.

It is best to choose paints that are intended to be used in a set (primer undercoat and finish) and to adhere to the manufacturer's recommendations for preparation and number of coats at each stage.

Wet rot is a frequent problem for old timber windows. The best way to stop it developing is to remove sections that are damaged or rotten as soon as you can to stop the spread of the fungus that causes it. Replace rotting wood with slow-growing deal (pine), and if possible, the same type of wood that is being removed, to avoid any differential movement.

In the late the 17th and early the medieval periods, glass became more affordable and plentiful so that glazed openings in timber-framed structures gradually became more elegant with wooden tracery as well as moulded mullions and projecting cills. In recent times, glass was pinned into frames that were rebated using glazing sprigs instead of lead cames. This method of glazing not only makes windows less likely to leak, but also allows for wider sheets of clearer glass to be utilized than would have been possible otherwise without the use of leaded lights.

Energy efficiency

Traditional timber windows provide an excellent energy performance due to their thickness and multi-layer construction. They also pay careful attention to detailing. They also feature large glass areas and projection cills which reduce air infiltration. With secondary glazing and draught proofing, the windows can be improved to improve their energy efficiency. However it is essential to keep in mind that any such measures should be viewed in relation to the overall quality and appearance of the condo window repair in its original form.

Therefore, keeping old windows that are in need of repair instead of replacing them is logical particularly when thermal enhancements can be achieved cost-effectively through simple repairs and improvements. Older windows are usually considered to be of historical value because they reflect a variety of technical development and changes to architectural style. The pressures to replace such windows are usually based on the assumption that old windows will need replacement in the near future, however most are still capable of providing service for 150, 200 or even 250 years, if properly maintained.

It is crucial to understand that decay issues associated in traditional timber windows are preventable by timely and thorough repairs. Additionally it is crucial to recognize damp penetration issues and fix them promptly to avoid major damage. The early deterioration of paint is a major issue, as it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this type of damage to go unnoticed until the paintwork starts to crack or turn curly. However, it can cause structural damage and further decay.

A quality paint will stop moisture from entering the paint. To avoid condensation and mould it is crucial to keep the paintwork as clean as it can be. Modern synthetic paints pose a challenge because they are often water-resistant and may cause mildew growth within the window frame.

The majority of windows from the past were constructed from timber with a high proportion of sapwood. These timbers are susceptible to deterioration rapidly if exposed to wet weather, but can be protected by an extensive preservative treatment prior to when they are put to use.
