It Is The History Of Cambridge Window In 10 Milestones
Maintaining Timber Windows

A well-maintained wooden window is an important component of a historical building. It reflects in different degree the materials and technologies of the time in which it was made, the architectural style and craftsmanship.

When repairs are feasible to windows that are already in use should be done in situ. Repairing the worst areas of decay can be accomplished using proprietary resin-based systems.

Durability

Timber windows were designed to last for centuries. However, they do need to be maintained to ensure that they look good and operating properly. The most frequently-asked maintenance tasks are repairs to sash-cords and re-tightening the sash pulleys and painting. There is also a rising demand for upgrading timber windows to improve energy efficiency. This may include replacing old glazing units, fixing existing window rebates, or installing new cills to improve 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 very large. In these instances, water can penetrate paint film and cause rotting to the putty or wood beneath. Weather conditions that are not ideal can accelerate the decay. To stop this from happening, windows should be regularly painted with an exterior wood paint.

In addition to repainting, corroded areas need to be repaired with the help of a resin-based repair solution. This will ensure that the maximum possible amount of the original fabric remains. It is also necessary to limit the number of holes that are drilled into the frame to allow cable entry as these can let in water and cause decay.

Another issue with older windows is the structural movement within the wall, which could cause deformation of the frame and sash. This can lead to the sash not fitting properly and jamming or sticking to the opening and cracked glazing. Most often, this is corrected by fitting new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill must be constructed from a sturdy hardwood such as oak to prevent movement between the existing and new work.

There are several companies that make Boston pattern wooden sash that fit most existing openings. These sash are available in a variety of sizes and finishes to meet the needs of today's homeowner. Combined with quadruple draught strips and better thermal insulation these sashes can make a an enormous difference to the energy efficiency of a house.

Aesthetics

Many old timber frames have a high aesthetic appeal, as they reflect, in some form, the quality of the wood technology, the construction process, and the architectural style of the time they were constructed. They may have significant historical significance as a set. This is especially true of windows that were unglazed in the early days of timber-framed buildings, where the majority of them were series of openings within frames of structural construction, which were divided horizontally by mullions and vertical iron or wood bars in order to keep out invaders.

Traditional window joinery made from timber is a beautiful element of a structure and it is important to keep its appearance. When you spot any decay caused by the penetration of moisture, it is important to stop it. It is recommended to do this through thorough painting, especially where there has been damage or deterioration. It is recommended to choose paints that are intended to be used in a system (primer undercoat and finish) and adhere to the manufacturer's recommendations for preparation and number coats at each stage.

The fungus that causes wet rot can quickly spread in old timber windows. To prevent this from happening, take out any damaged or rotten parts as soon as you can. The replacement of wood that is rotting should be done with care and with a slow-growing deal (pine) and, if possible, the same species as that which is being removed to avoid differential movement between the new section and existing timbers.

window installation services cambridge became more affordable and abundant in the late medieval period and into the 17th century. As a result, the glazed openings in timber-framed homes became more complex with moulded mullions, wooden tracery and cills that protruded deep. In recent years, glass was fixed into rebated frames with glazing sprigs rather than lead cames. This method of glazing is not only less prone to leaking but it also allows much wider and clearer sheets of glass to be used in the windows than would have been possible without the need for leaded lights.

Energy efficiency


Traditional timber windows are energy efficient due to their thickness, multilayer construction and attention to particulars. They also have large glass areas and projecting cills that minimise air infiltration. Windows can be designed to increase their energy efficiency by draught-proofing and secondary glazing. It is important to remember that these measures must be taken into consideration in relation to the overall integrity and appearance of the original windows.

So, retaining old windows that are in need of repair instead of replacing them is logical, particularly when their thermal enhancements can be achieved economically through simple repairs and upgrades. The windows of the past often have an historic value that demonstrates a range of technological advances and changes in architectural taste. The pressure to replace these windows are usually based on the assumption that the windows of the past will require replacement in the near future, but they are capable of providing service for 150, 200 or even 250 years, if properly maintained.

It is important to recognise that the decay issues associated with traditional windows made of timber can be avoided by thorough maintenance and timely repairs. It is also crucial to identify damp problems and fix them quickly in order to avoid major damage. Paint deterioration that occurs early is a concern because it allows moisture to penetrate into the wood, leading to wet rot. This damage is often not noticed until the paintwork is cracking or wavy however, it can cause serious structural damage, and could lead to further decay.

A paint of good quality will block moisture penetration. To prevent mould and condensation it is crucial to keep the paintwork as clean as possible. Modern synthetic paints pose a problem because they are water-resistant and can cause mildew to develop within the window frame.

The majority of windows from the past were manufactured from timber containing a high proportion of sapwood. These timbers can deteriorate quickly when exposed to rain, however they can be protected with a thorough preservation process prior to use. It is crucial to select the right kind of wood for your location and the climate, since these factors can affect the durability of the joinery. Local window manufacturers have a wide range of sash made from timber that can be made to fit the historic openings. They can be built according to the standard Boston pattern dimensions, or to custom sizes that fit with the historic architecture.

Maintenance

Regular inspections carefully redecorated, as well as prompt repairs can extend the life of wooden windows. The major cause of decay is moisture leaking through deteriorated paint or putty. This can be avoided with careful painting and using high-quality wood preservative.

It is important that repairs to old sash and casement windows are well executed and done without causing any disturbance. It is possible to fix the majority of traditional wooden window designs without taking the frame off. This should be done as often as is feasible. Loose or peeling paint should be removed carefully and sanded lightly to increase the key of the surface, allowing for a better adhesion of the new coating. It is important to avoid removing old paint layers, which may have historical value.

If a portion of wood is decayed the best way to deal with it is to remove it and replace it with timber inserts shaped to match the existing profiles. The inserted timber should also be treated with a wood preservative, and the joint between the masonry sub-cill and the timber cill should be sealed.

It is tempting to replace traditional windows with PVC U, particularly when the installer provides an installation that includes removal and replacement in a single day. It is important that the installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will allow them to make appropriate suggestions for energy efficiency improvements and other technical upgrades that will not harm the historical character of a building. Window replacements should be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are approved as a suitable solution in accordance with Building Regulations. It is certainly possible for a skilled and experienced carpenter to install PVC-u windows that are sympathetic to the style of the original building. This is particularly true when the windows are situated within listed buildings or conservation areas.
