Maintaining Timber Windows

A well-maintained wooden window is an important component of a historical building. It is a representation of the various materials and techniques as well as the craftsmanship and architectural style of the period from which it originates.

When possible, repairs should be made on-site. Repairing the most severe areas of decay can be done using proprietary resin-based systems.

Durability

The windows made of timber in many historical buildings were built to last for window Mechnism Repair centuries. They require regular maintenance to keep them looking good. Maintenance tasks include sash cord repairs and retightening pulleys on sash, and painting. There is a growing need to upgrade the timber windows to increase the efficiency of energy. This may mean replacing old glass units, fixing existing window Mechnism repair rebates or putting in new cills to allow for better air sealing.

A key problem with traditional windows is the damage caused by the corrosion of the paintwork. This is especially true in the case of sash windows because the gaps between sashes can be quite large. In these situations water may get through the paint film and cause decay of the putty and the wood underneath. The rotting can be exacerbated due to weather conditions that are poor. To avoid this, windows should be painted regularly with an exterior wood paint that is suitable.

The areas that are damaged should be repaired with resin-based products. This will ensure that the maximum amount of the original fabric is retained. It is essential to limit the number of holes that are made in the frame to allow cable access, as these can admit moisture and cause decay.

Another significant problem with older windows is the structural movement within the wall, which can cause deformation of the frame and the sash. This could result in sash no longer fitting correctly and jamming or sticking to the opening and cracked glazing. This is often corrected by putting in new sash frames constructed of slow-growing deal (pine), or oak. The cill should be made from a sturdy hardwood such as oak to prevent movement between the new and existing work.

To help reduce this problem There are several companies that manufacture Boston pattern sash made of wood that will fit into the majority of existing openings. They are available in a variety of sizes and finishes to suit the needs of modern-day homeowners. Combined with quadruple draught strips and improved thermal insulation, these sashes can make a a substantial difference to the energy efficiency of a home.

Aesthetics

Many old wooden windows have an excellent aesthetic value since they usually demonstrate, in a way the materials and technologies and architectural style of the time from when they were built. They also may have a significant historic value in their in their own right. This is particularly true of early unglazed window openings in timber-framed buildings, which were just a collection of openings within the structural frame sub-divided horizontally into mullions and iron or wood bars to deter intrusions.

It is crucial to maintain the appearance of traditional wooden window joinery. It is vital that any decay caused by the penetration of moisture should be stopped as soon as it is identified. It is recommended to do this by thorough painting, especially where there is damage or deterioration. It is best to choose paints that are intended to be used in a system (primer undercoat and finish) and to follow the manufacturer's guidelines for preparation and number of coats at each stage.

The fungus that causes wet rot is able to spread quickly in old windows made of timber. To prevent this from happening, take out any damaged or rotten parts as soon as you can. The replacement of rotting timber must be done with care 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 and old timbers.

Glass became more affordable and abundant in the late medieval era and into the 17th century. This led to glazed openings on timber-framed houses were more elaborate, with moulded mullions, tracery made of wood and deep cills projecting into the air. In recent years, glazing was fixed to rebated frames with glazing sprigs rather than lead cames. This method of glazing is not just less susceptible to leaks, but it also allows larger, clearer sheets of glass to be used in the windows than would have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows are energy efficient because of their thickness and multilayer construction as well as focus on the smallest of details. They also have large glass areas and projection cills which reduce air infiltration. The windows can be modified to improve their energy efficiency with draught-proofing and secondary glazing. It is essential to keep in mind that these measures need to be taken into consideration when it comes to the overall integrity and look of the original windows.

It makes sense to fix or Repairs to Upvc doors upgrade windows that are older rather than replacing them, especially when the improvement in energy efficiency can be made by simple repairs. The windows of the past often have historical significance that illustrates a variety of technological advancement and changes in architectural style. The pressures to replace these windows are usually based on the assumption that the windows that are old will need to be replaced in the near future, however they are in a position to last for 150, 200 and even 250 years, if properly maintained.

It is crucial to understand that decay problems with traditional timber windows are preventable by quick and thorough repairs. In addition it is vital to recognize damp penetration issues and to remedy them quickly to avoid serious damage. Early paint deterioration is a particular problem, as it allows moisture to penetrate the wood and cause wet rot. The damage is usually not apparent until the paintwork is wavy or cracked, but can cause significant structural damage, and could lead to further decay.

A high-quality paint will prevent this moisture penetration. It is also essential to keep the paintwork clean to avoid mould and condensation. Modern synthetic paints can pose a problem since they are typically made to be water-resistant which can result in the formation of mildew in the window repairs cambridge 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, however they can be preserved with an extensive preservation treatment prior to use. It is essential to select the right type of wood for the site and the climate, Window lock Repairs since these factors can affect the durability of the joinery. Local window manufacturers have various types of timber sash which can be customized to fit historic openings.

It is important to avoid stripping paint layers that may have historic value and if they are present it is recommended that a study of the paint be conducted.

If a piece of timber has begun to decay, the best way to proceed is to take out the rotten material and replace it with spliced-in timber inserts that are shaped to fit the existing profiles.

Replacement of windows made of traditional PVC-u may be a tempting option, especially when the installer offers an "all-in-one" installation that handles removal and replacement in a day. However, it is essential that the person installing windows replacement has a thorough knowledge of the structure and history of traditional timber frames.
