Maintaining Timber Windows

A well-maintained wooden window is an essential component of a historical building. It reflects, in various degree the technology and materials of the time period it was made, the craftsmanship and architectural taste.

If repairs are possible to existing windows are required, they should be done in-situ. The repair system that is based on resin can be used to fix the most damaged areas of decay without removing the whole window restoration cambridge.

Durability

Timber windows were made to last hundreds of years. However, they do need to be maintained to ensure that they look great and working properly. Maintenance tasks include repairs to sash cords as well as tightening the sash pulleys and painting. There is a growing need for upgrading timber windows to improve energy efficiency. This may mean replacing old glass units, fixing the window rebates that are in place, or installing new cills to allow for better air sealing.

One of the major issues with traditional windows is damage caused by corrosion of the paintwork. This is particularly important when windows made of sash are involved because the gaps between sashes can be very large. In these circumstances water can get into the paint film and cause rotting of the putty and the wood beneath. The rotting process can be made worse due to weather conditions that are poor. To stop this from happening, windows need to be painted regularly with an exterior wood paint.

Areas that have been damaged must be repaired using resin-based products. This will ensure that the highest possible amount of the original fabric remains. It is also essential to reduce the number of holes you drill into the frame to allow cable entry as these can let in water and cause decay.

Another significant problem with older windows is structural movement in the wall, which can cause deformation of the frame and sash. This can result in the sash not fitting properly or sticking or jamming into the opening and Doors Cambridge broken glazing. This can be fixed frequently by fitting new sash frames made of slow-growing deal (pine) or discuss oak. The cill should be constructed from a sturdy hardwood, like oak, to prevent shifting between the new and older work.

There are now several companies that produce Boston pattern wooden sash that fit in with the majority of openings. The sash is available in a range of sizes and finishes that meet the needs of the modern homeowner. These sash are combined with quadruple draft strip and a better thermal insulation, can make a significant difference to the energy-efficiency of a home.

Aesthetics

Many old wooden windows have an excellent aesthetic value since they usually show, in a particular way, the materials and technology and architectural style of the time in which they originate. They could have significant historical value as a set. This is particularly true for early unglazed windows in timber-framed buildings, where the majority were series of openings in structural frames that were subdivided horizontally by mullions, and vertically by wood or iron bars in order to protect against invaders.

Traditional window joinery made from timber can be a stunning aspect of a building, and is crucial to maintain its appearance. It is vital that any decay caused by moisture penetration should be immediately stopped once it is discovered. It is recommended to do this through thorough painting, especially where there is damage or deterioration. It is recommended to use paints that are designed 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.

Wet rot is a common problem in old timber windows. The best way to stop it becoming a problem is to take out any damaged or rotten sections as soon as possible to prevent the spread of the fungus that causes it. The replacement of rotting wood must be done with care using slow grown deal (pine) and, if feasible using the same species as which is being removed to avoid shifting between the new and old timbers.

In the late period of the 17th century and the middle of the medieval period, glass became cheaper and more abundant, and the openings for glazed glass in timber-framed buildings gradually became sophisticated, with tracery made of wood moulded mullions, moulded mullions, and deep protruding cills. The glazing was increasingly laid within rebated frames and secured with 'glazing sprigs', rather than into lead cames. This method of double glazing windows cambridge not only makes windows less likely to leak and break, but also allows wider sheets of clearer glass to be employed than would be feasible without the use of leaded lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness and multilayer construction, as well as their attention to the smallest of details. The large glass surfaces, the deep projection cills and wide glazing areas help to reduce air infiltration. With secondary double glazing windows cambridge and draught proofing, the windows can be improved to improve their energy efficiency. It is crucial to keep in mind that these measures need to be taken into consideration when it comes to the overall appearance and integrity of the original windows.

So, retaining existing historic windows that require repair rather than replacing them is sensible, particularly when their thermal enhancements can be achieved economically through simple repairs and improvements. Historic windows often have a historical value that illustrates a variety of technical development and changes in architectural style. The pressure to replace these windows are usually based on the assumption that the old windows will need replacement in the near future, but they are in a position to last for 150, 200 or even 250 years if they are properly maintained.

It is essential to realize 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 address them swiftly to prevent serious damage. Early paint deterioration is a major issue, because it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this type of damage to go unnoticed until the paintwork starts to crack or turn wavy. However, it could cause structural damage and further decay.

A quality paint will stop moisture from entering the paint. It is also essential to keep the paintwork spotless to avoid condensation and mould growth. Modern synthetic paints are problematic because they are water-resistant and can cause mildew to grow within the window frame.

The majority of windows from the past were constructed from sapwood-rich wood. These timbers are susceptible to deterioration quickly when exposed to moist weather, but can be protected by a thorough preservative treatment before they are put to use. It is also crucial to ensure that the type of wood used is suitable to the climate and site conditions, Lock Replacement Cambridge as these factors can affect the longevity of the joinery. Local window manufacturers make various types of timber sash that can be tailored to fit specific openings in historic buildings. They can be constructed according to the standard Boston pattern dimensions or to specific dimensions that are compatible with historic buildings.

Maintenance

Regular inspections carefully redecorated, as well as timely repairs can prolong the life of wooden windows. The primary cause of wood decay is moisture penetration through deteriorated paint and putty. This can be prevented by careful painting and the use of a good quality wood preservative.

It is essential that repairs to old sash or casement windows are well executed and done with minimal disruption. Many traditional timber window designs are repairable without removing the frame, and this approach should be followed whenever possible. Loose or peeling paint should be removed carefully and lightly sanded to improve the "key" of the surface and facilitate an improved adhesion of the new coating. Care should be taken to avoid stripping paint layers that might have historical significance and if they are present, it is recommended that a paint analysis be conducted.

If a portion of wood is decayed, the best solution is to take it off and replace it with timber inserts designed to match the existing profiles. The timber that is inserted should be treated with a wood preservative. The junction between the masonry sub-cill and the timber cill should be sealed.

Replacement of windows made of traditional PVC-u is a tempting option, especially when the installer offers an "all-in-one" installation that handles removal and replacement within a day. It is, however, 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 appropriate recommendations for energy efficiency improvements and other technical upgrades that will not harm the character of a historic building. Anyone who installs lock Replacement cambridge windows should be registered with a Competent Persons Scheme, Lock Replacement Cambridge such as FENSA. This will ensure that the replacement windows are approved as a suitable option under Building Regulations. It is quite possible for an experienced and skilled carpenter to install PVC-u windows that are sympathetic to the character of the building originally. This is especially true where the windows are located in listed buildings and conservation areas.
