Durability

Timber windows were designed to last hundreds of years. However, they do need to be maintained to ensure that they look good and operating properly. Maintenance tasks include repairs to sash cables, retightening of pulleys on sash, and painting. The need to upgrade timber windows in order to increase efficiency in energy use is also growing. This can include replacing old double glazing company cambridge 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.

In addition to repainting, areas that have corroded need to be repaired with an adhesive-based repair product. This will ensure that the greatest amount of original fabric is retained. It is important to minimize the number of holes made into the frame in order to allow cable entry since they can let in moisture and cause decay.

Another significant problem with older windows is structural movement in the wall that could cause deformation of the frame and the sash. This can lead to the sash not fitting properly jamming, sticking or sagging in the opening, or breaking glass. Often this can be corrected by the fitting of new windows cambridge sash boxes that have been made from slow grown deal (pine) or oak. The cill should be made from a sturdy hardwood such as oak to prevent movement between the existing and new work.

There are a variety of companies that make Boston pattern wooden sash to fit into the majority of existing openings. These sash are available in a range of sizes and finishes to suit the needs of the modern homeowner. In conjunction with quadruple draught strip and better thermal insulation these sashes can make a significant improvements to the energy efficiency of a house.

Aesthetics

Many old wooden windows have an excellent aesthetic value as they often illustrate, in some way the materials and techniques and architectural taste of the period from which they date. They may also have a significant historical significance in their own right. This is especially true of windows that were unglazed in the early days of timber-framed buildings, which were merely a series of openings in the frame that were subdivided horizontally into mullions, and vertically into iron or wood bars to deter intruders.

Traditional window joinery made from timber can be a highly decorative aspect of a building, and it is important to keep it looking good. As soon as you see any signs of decay due to moisture penetration, it is important to stop it. It is recommended to do this through thorough painting, particularly if there is damage or deterioration. It is recommended to choose paints that are intended to be used in a system (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 typical problem for old timber windows. The best way to stop it developing is to remove any damaged or rotten sections immediately to stop the spread of the fungus that causes it. Replace rotting wood with slow-growing deal (pine), and should it be possible, the same type of wood as the one being removed, to prevent differential movement.

In the late the 17th and early the medieval periods, glass became less expensive and more abundant, and the openings for glazed glass in timber-framed structures gradually became more sophisticated with wooden tracery, moulded mullions and deep projecting cills. In recent years, glass was fixed to frames that were rebated with glazing sprigs instead of lead cames. This method of glazing not only makes the windows less likely to leak and break, but also allows wider sheets of clearer glass to be utilized than would have been possible otherwise without the use of lead lights.

Energy efficiency

Traditional timber windows provide excellent energy efficiency due to their thickness, multi-layer construction and very attentive attention to detail. The large glass areas, « Back deep projecting cills, and the large glazing areas help to reduce air infiltration. The windows can be made to increase their energy efficiency through draughtproofing and secondary glazing. It is important to keep in mind that these measures need to be considered when it comes to the overall integrity and appearance of the original windows.

So, retaining the existing windows from the past that are in need of repair instead of replacing them makes sense particularly when thermal improvements can be achieved inexpensively with simple repairs and upgrades. Older windows cambridge typically have an historic value that demonstrates a range of technological advancement and changes in architectural style. The pressures to replace these windows are typically based on the assumption that windows of the past will require replacement in the near future, but most are still capable of providing service for 150, 200 or even 250 years, if properly maintained.

It is essential to understand that the decay issues caused by traditional timber windows can be prevented by regular maintenance and prompt repairs. In addition, it is essential to recognize damp penetration issues and fix them promptly to prevent serious damage. The early deterioration of paint is a particular problem, since it allows moisture penetrate the wood and cause wet rot. It is not uncommon for this issue to go undetected until the paintwork begins to crack or becomes wavy. However, it can cause structural damage and lead to further decay.

A good quality paint will prevent this moisture penetration. To prevent condensation and mould, it is important to keep the paintwork as clean as possible. Modern synthetic paints pose a problem since they are usually water-resistant, and can cause mildew growth within the window frame.

Most older windows were made from sapwood-rich wood. These timbers are susceptible to deterioration quickly when exposed to wet weather conditions, but they can be protected with a thorough preservative treatment before they are put to use. It is also important to ensure that the type of wood used is suited to the climate and site conditions, since these factors affect the durability of the joinery.
