10 Unexpected Cambridge Window Tips

Maintaining Timber Windows

A well-maintained wooden window repair specialists is an essential component of a historical building. It reflects, in various levels, the materials and technologies of the time in which it was made, the craftsmanship and architectural taste.

If it is possible, repairs must be made in-situ. Repairing the most severe areas of decay is possible using proprietary resin-based systems.

Durability

The timber windows in many historic structures were designed to last for centuries. They require regular maintenance to ensure they look good. The most frequently-asked maintenance tasks are repairs to sash-cords as well as tightening sash pulleys and painting. The demand for enhancing windows made of timber to improve efficiency in energy use is also growing. This could include replacing old glazing units, repairing existing window repair specialists rebates or installing new cills for improved air seal.

The corrosion of paintwork is a major problem with traditional windows. This is particularly important when sash windows are involved as the gaps between the sashes can be quite wide. In these instances water can get into paint film and cause rotting of the wood or putty underneath. The weather can be a factor in accelerating the decay. To prevent this from happening, windows need to be regularly painted with an exterior wood paint.

In addition to repainting, areas that have corroded must be repaired using a resin-based repair product. This will ensure that the greatest amount of original fabric preserved. It is also important to limit the number of holes that are 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 the sash. This could result in the sash not fitting properly, sticking or jamming in the opening, and damaged glazing. This can be fixed frequently by putting in new sash frames made of slow-grown deal (pine), or oak. The cill should be constructed from durable hardwood such as oak to prevent movement between the old and new work.

To reduce the risk to reduce the risk of this happening, there are a variety of companies that manufacture Boston pattern sash made of wood that will fit into the majority of existing openings. The sash is available in a variety of sizes and finishes to suit the needs of modern-day homeowners. The new sash, combined with quadruple draft strip and improved thermal insulation can significantly improve the energy-efficiency of a home.

Aesthetics

Many old timber frames possess a dazzling aesthetic appeal, since they show, in some form, the quality of the wood technology, design, and taste from the time period they were built. They could also have a significant historic value in their own right. This is particularly true of early windows that were not double glazed door seal repairs in timber-framed buildings, which were merely a series of openings within the frame, which were divided horizontally into mullions and wood or iron bars to deter intrusions.

It is important to maintain the appearance of traditional wooden window joinery. When you spot any decay caused by moisture penetration it is crucial to stop it. It is recommended to do this through thorough painting, especially if there is damage or deterioration. It is advisable to use paints specifically designed to be used part of a system (primer, undercoat and finish) and follow the manufacturer's guidelines regarding preparation and the number of coats needed at each stage.

Wet rot is a frequent problem for old timber windows and the best method to stop it from growing is to eliminate any damaged or rotten sections as soon as you can to prevent the spread of the fungus responsible for it. The replacement of wood that is rotting should be carefully undertaken with a slow-growing deal (pine) and, if feasible, the same species as that which is being removed to avoid any movement differences between the new and old timbers.

Glass became less expensive and more abundant in the late medieval era and into the 17th century. In the process, the openings for glazed windows on timber-framed houses were more elaborate, with moulded mullions, wooden tracery and cills that protruded deep. In recent years, glass was fixed to frames that were rebated with glazing sprigs rather than lead cames. This method of glazing is not just less prone to leaking but it can allow for more expansive, clearer sheets of glass to be used in the windows than would be possible without the need for lead lights.

Energy efficiency

Traditional timber windows offer a good energy performance due to their thickness, multi-layer construction and very meticulous attention to detail. The large glass areas, deep projecting cills, and the large glazing areas reduce air infiltration. With secondary glazing and draughtproofing windows can be upgraded to improve their energy efficiency. It is crucial to keep in mind that these measures need to be considered in relation to the overall appearance and integrity of the original windows.

It is sensible to repair or upgrade existing windows that are older rather than replacing them, especially when the improvement in thermal efficiency can be made through simple repairs. Historic windows often have historical significance that demonstrates a range of technological advancement and changes in architectural style. Most people think that these windows will need to be replaced in the near future. However, many of them are still in service for 150,200, and even 250 years with proper maintenance.

It is crucial to recognize that the decay issues caused by traditional timber windows can be avoided by regular maintenance and timely repairs. In addition it is crucial to identify damp penetration problems and address them swiftly to avoid serious damage. The early deterioration of paint can be a problem because it allows moisture to get into the wood, leading to wet rot. It is not uncommon for this issue to go unnoticed until the paintwork begins to crack or become curly. However, it could cause structural damage and lead to further decay.

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

Most older windows were made from sapwood-rich wood. The timbers will deteriorate rapidly if exposed to wet weather conditions, but they can be protected with an extensive preservative treatment prior to when they are put to use. It is important to choose the right kind of wood for the location and climate, as these variables can affect the durability of the joinery. Local window manufacturers create a variety of timber sash that can be tailored to fit specific historic openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to historical structures.

Maintenance

The life span of windows made from timber can be extended considerably through regular inspections, careful redecoration and timely repair. The major cause of decay is the penetration of moisture through deteriorated paint or putty. This can be avoided by careful painting and using high-quality wood preservative.

Repairs to sash windows that are old and frameless casement windows should be done with care and with minimal disruption. A lot of traditional wooden window designs are repairable without removing the frame, and this method should be taken whenever feasible. Peeling or loose paint should be removed with care and lightly sanded to improve the "key" of the surface and facilitate an improved adhesion of the new coating. It is crucial to not remove old paint layers, as they could have historical significance.

When a section of wood has rotted the best way to deal with it is to take it off and replace it with timber inserts shaped to match existing profiles. The wood that is inserted should be treated with a wood preservative and the connection between the cill for timber and the sub-cill of the masonry should be sealed.

Replacement of traditional windows using PVC-u may be a tempting option, especially when the installer offers a "one-stop shop" installation service that can handle removal and replacement within one day. It is important that the installers of replacement windows have a thorough understanding of the history and design of traditional timber frames. This will enable them to make appropriate suggestions for energy efficiency improvements and other technical upgrades that won't harm the historic character of a building. Window replacements should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacements are deemed acceptable by the Building Regulations as a suitable option. A skilled carpenter can put in PVC-u Windows that are sympathetic to original building's character. This is especially true when windows are installed in listed buildings and conservation areas.
