Maintaining Timber Windows

A well-maintained wooden window repair cambridge is a crucial component of a historical building. It reflects, in various degree the technology and materials of the time it was constructed, as well as the architectural style and craftsmanship.

If possible, repairs should be made in-situ. Proprietary resin-based repair systems can be used to repair the worst areas of decay without removing the whole window.

Durability

The windows made of timber in many historic buildings were built to last for centuries. However, they do need to be maintained to ensure that they look good and functioning correctly. Maintenance tasks include repairs to sash cables and retightening pulleys on sash, and painting. The demand for upgrading windows made of timber to increase efficiency and energy efficiency is also increasing. This could mean replacing old glazing units, fixing the window rebates that are in place or putting in new cills that allow for better air sealing.

The corrosion of paintwork is a major issue with traditional windows. This is especially important when sash windows are concerned as the gaps between sashes may be very large. In these situations water can get into paint film and cause rotting of the putty or wood beneath. Weather conditions that are not ideal can accelerate the rotting. To stop this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, areas that have corroded need to be repaired with a resin-based repair product. This will ensure that the maximum amount of original fabric is retained. It is important to minimize the number of holes drilled into the frame to allow cable entry because they could let in moisture and cause decay.

The wall's structural movement could also cause distortions in the frame as well as the sash. This can result in the sash not fitting properly and jamming or sticking to the opening, and damaged glazing. Most often, this is corrected by fitting new sash boxes that have been made from slow grown deal (pine) or oak. The cill must be constructed of a durable hardwood like oak to prevent movement between the existing and new work.

To help reduce this problem to reduce the risk of this happening, there are a number of companies who manufacture Boston pattern wooden sash that can be fitted into most openings. The sash is available in a variety of sizes and finishes that will meet the requirements of modern homeowners. Combined with quadruple draught strips and better thermal insulation these new sash options can make a substantial difference to the energy efficiency of a home.

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 time from which they date. They may also have a significant historic value in their in their own right. This is particularly true of early windows that were not glazed in timber framed buildings which were merely a series of openings in the frame, which were divided horizontally into mullions and vertical wood or iron bars to deter intruders.

It is essential to preserve the appearance of traditional timber upvc window lock Repair joinery. When you spot any signs of decay due to the penetration of moisture, it is important to stop it. This can be done by painting thoroughly, especially in areas in which there is already damage or deterioration. It is recommended 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 regarding preparation and the amount of coats required at each stage.

The fungus that causes wet rot can spread quickly in old cambridge windows and doors made of wood. To prevent this, get rid of any damaged or rotten components as soon as you can. Replace the wood that is rotting with slow-growing deal (pine) and, if possible, the same kind of timber that is being removed, to prevent any differential movement.

In the late medieval and 17th century periods glass became less expensive and more abundant, so that the glazed openings in timber-framed buildings gradually became sophisticated with wooden tracery, moulded mullions and deep protruding cills. Increasingly, the glazing was laid within rebated frames and secured by 'double glazing near me sprigs' rather than being inserted into lead cames. This method of glazing is not only less prone to leaks but also allows for more expansive, clearer sheets of glass to be used in windows than would otherwise be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows offer an excellent energy performance due to their thickness and multi-layer construction, as well as careful attention to detailing. They also feature large glass areas and deep projecting cills that minimise air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to improve their energy efficiency. It is essential to remember that these measures must be taken into consideration when it comes to the overall integrity and appearance of the original windows.

So, retaining old windows that are in need of repair rather than replacing them is sensible especially when their thermal enhancements can be achieved cost-effectively through simple repairs and improvements. Older windows are usually of historical significance, since they reflect a variety of technological advancement 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 crucial to recognize that the decay problems associated with traditional timber windows can be avoided by thorough maintenance and swift repairs. It is also important to identify damp problems and fix them quickly in order to avoid major damage. Early paint deterioration could be a problem as it allows moisture to penetrate into the wood, which can cause wet rot. It is not uncommon for this type of damage to go unnoticed until the paintwork starts to crack or Upvc Window Lock Repair turn curly. However, it can cause structural damage and further decay.

A good quality paint will prevent this moisture penetration. To prevent condensation and mould it is crucial to keep the paintwork as clean as you can. The use of modern synthetic paints can pose a problem since they are typically made to be water-resistant and this can cause the growth of mildew inside the window frame.

The majority of older windows were constructed from timber with a high proportion of sapwood. These timbers can deteriorate quickly when exposed to rain, but they can be protected with a thorough preservation process prior to use. It is also important to ensure that the type of wood used is suited to the climate and site conditions, as these factors will influence the durability of the joinery. Local window manufacturers provide an array of timber sash which can be customized to fit historic openings. They can be built to the standard Boston pattern dimensions, or to custom dimensions that are compatible with historic buildings.

Maintenance

Regular inspections as well as careful redecoration and quick upvc doors repairs can prolong the life of timber windows. The major cause of decay is moisture penetration through deteriorated paint or putty. This can be avoided by thorough painting and the use of a good quality wood preservative.

It is important that repairs to old sash and casement windows are well executed, and carried out without causing any disturbance. Repairs can be made to many traditional timber window designs without taking the frame off. This should be done as often as is feasible. Paint that is peeling or loose should be removed carefully and lightly sanded to improve the key of the surface and facilitate an improved adhesion of the new coating. It is important to avoid stripping old paint layers which may have historic value and if they are present it is recommended that a paint analysis be conducted.

If a piece of wood is rotting the best way to deal with it is to remove it and replace it with timber inserts designed to match existing profiles. The wood that is being inserted should be treated with a wood preservative and the joint between the timber cill and sub-cill for masonry should be sealed.

Replacement of traditional windows with PVC-u is a tempting option, especially when the installer offers a "one-stop shop" installation that takes care of removal and replacement in one day. It is crucial that the person who installs replacement windows has a full knowledge of the construction and history of traditional wooden frames. This will allow them to make the appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't harm the character of a historic building. Anyone who installs replacement windows must be registered under a Competent Persons Scheme like as FENSA. This will ensure that the replacements are deemed as a suitable solution in accordance with Building Regulations. A skilled carpenter is able to install PVC-u windows that are suited to the original building's style. This is especially true where windows are installed in listed buildings and conservation areas.
