Durability

Timber windows were built to last for centuries. However, they need to be maintained to ensure that they look great and working properly. The most common maintenance tasks are repairs to sash-cords as well as tightening sash pulleys and painting. The demand for enhancing timber windows in order to increase efficiency and energy efficiency is also increasing. This may include replacing old glazing units, fixing existing window rebates, or installing new cills to increase the air seal.

One of the major issues with traditional windows is the damage caused by the corrosion of the paintwork. This is particularly true when sash windows are involved as the gaps between the sashes can be quite wide. In these instances water can get into the paint film and cause decay of the putty and the wood underneath. The rotting process can be made worse by weather conditions that are not ideal. To prevent this from happening, windows should be regularly painted with an exterior wood paint.

The areas that are damaged should also be repaired using a resin-based product. This will ensure that the highest possible amount of the original fabric is retained. It is crucial to reduce the number of holes that are created into the frame to allow cable entry since they can let in moisture and cause decay.

Another major issue with older windows is the structural movement within the wall, which can lead to deformation of the frame and sash. This can result in the sash window repair cambridge not fitting properly and jamming or sticking to the opening and broken glazing. This can be corrected often by fitting new frames for sash made of slow-growing deal (pine), or oak. The cill must be made from a sturdy hardwood, such as oak, to prevent the movement of new and old work.

There are a variety of companies that make Boston pattern wooden sash to fit into the majority of existing openings. They are available in a variety of sizes and finishes to suit the needs of today's homeowner. Together with quadruple draught strips and better thermal insulation these sashes can make a significant improvements to the energy efficiency of a house.

Aesthetics

Many old timber windows have a high aesthetic value as they often demonstrate, in a way the materials and techniques and architectural taste of the period from which they date. They could also have a significant historical significance in their in their own right. This is especially true of early windows that were not glazed in timber-framed buildings, where the great majority were simply a series of openings in the frame that were subdivided horizontally into mullions and iron or wood bars to deter intruders.

Traditional timber window repair near me joinery can be a highly decorative element of a structure and is essential to keep it looking good. It is crucial that any decay that results from the penetration of moisture should be stopped as soon as it is identified. This is best done by a thorough painting process, especially in areas where there has already been damage or deterioration. It is advisable to use paints that are specifically designed to be used as part of a system (primer, undercoat and finish) and to follow the manufacturer's recommendations regarding preparation and the amount of coats required at each stage.

Wet rot is a typical problem in old timber windows. The best method to stop it from growing is to eliminate sections that are damaged or rotten as soon as possible to prevent the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine), and when possible, the exact type of wood that is being removed to prevent any differential movement.

Glass became cheaper and more abundant in the late medieval period and into the 17th century. In the process, the openings for double glazed door seal repairs windows on timber-framed houses were more elaborate, with moulded mullions, tracery made of wood and deep cills projecting into the air. In the past, more often, the glass was laid within rebated frames and then pinned by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing not only makes the windows less likely to leak, but also allows for wider sheets of clearer glass to be employed than would be possible otherwise without the use of led lights.

Energy efficiency

Traditional timber windows provide excellent energy efficiency 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 double glazing near me and draught proofing, the windows can be improved to improve their energy efficiency. It is crucial 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 the existing windows from the past that require repair rather than replacing them is sensible particularly when thermal enhancements can be achieved economically through simple repairs and upgrades. Older windows are usually of historical value, as they demonstrate a variety in technological advancement and changes in architectural style. The pressures to replace these windows are usually based on the assumption that the old windows will need cambridge replacement windows in the near future, however the majority of them are in a position to last for 150, 200 or even 250 years if they are properly maintained.

It is important to recognise that the decay problems associated with traditional timber windows can be avoided through regular maintenance and prompt repairs. Additionally it is vital to spot damp penetration issues and address them swiftly to avoid serious damage. Early paint deterioration could be a problem as it allows moisture to get into the wood, leading to wet rot. The damage is usually not evident until the paintwork becomes cracking or wavy but it can cause severe structural damage and can lead to further decay.

A high-quality paint will prevent this moisture penetration. It is also important to keep the paintwork clean to avoid mould and condensation. The use of modern synthetic paints can be problematic because they are usually formulated to be water-resistant, and this may lead to the formation of mildew inside the window frame.

The majority of windows from the past were constructed of sapwood-rich timber. The timbers will deteriorate rapidly if exposed to rain, but they can be protected with an extensive preservation treatment prior to use. It is important to choose the appropriate type of wood for the site and climate, as these variables will affect the durability of the joinery. Local window manufacturers create a variety of timber sash that can be adapted to fit specific openings from the past. They can be built to the standard Boston pattern dimensions, or to custom sizes that fit with historic buildings.

Maintenance

It is important to avoid stripping paint layers that may have historic value, and where these are present it is recommended that a paint analysis 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 match existing profiles. The timber inserts should be treated with wood preservative and the junction between masonry sub-cills and timber cill should be sealed.
