5 Cambridge Window Tips From The Pros

Maintaining Timber Windows

A well-maintained timber upvc window and door Repairs is a significant part of the historic fabric of a building. It reflects in different degree the materials and techniques of the time it was constructed, the architectural style and craftsmanship.

If repairs are possible to existing windows should be carried out in situ. Repair systems made of resin can be used to repair the most damaged areas of decay without having to remove the entire window.

Durability

The timber windows in many old structures were designed to last for a long time. However, they do need to be maintained to ensure that they look good and functioning properly. The most frequently-asked maintenance tasks are repairs to sash-cords, re-tightening sash pulleys, and painting. The need to upgrade timber windows in order to improve efficiency in energy use is also growing. This can include replacing old glazing units, repairing existing window rebates or installing new cills to increase the air seal.

One of the main issues with traditional windows cambridge is the damage caused by the corrosion of the paintwork. This is particularly important when sash windows are involved as the gaps between the sashes can be quite large. In these situations water can get into the paint film and cause rotting of the putty as well as the wood underneath. Poor weather conditions can exacerbate the rotting. To stop this from happening, windows need to be painted regularly with an exterior wood paint.

Corroded areas should also be repaired using a resin-based product. This will ensure that the highest possible amount of the original fabric is preserved. It is also important to limit the number of holes you drill into the frame to allow cable entry as these can let in water and cause decay.

The structural movement of the wall could also cause deformations in the frame and sash. This could result in sash no longer fitting correctly, sticking or jamming in the opening and cracked glazing. This can often be fixed by the fitting of new sash boxes that have been made from slow grown deal (pine) or oak. The cill needs to be constructed of a strong hardwood such as oak, to prevent differential movement between new and existing work.

There are now several companies that manufacture Boston pattern wooden sash that fit most existing openings. These sash are available in a variety of sizes and finishes that meet the needs of today's homeowner. These new sash, when coupled with quadruple draft strips and a better thermal insulation, can make a huge 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 taste of the period from which they date. They may have significant historical significance in their own right. This is especially true of windows that were unglazed in the early days of timber framed buildings which were simply a series of openings in the frame, which were divided horizontally into mullions and wood or iron bars to keep out invaders.

It is essential to preserve the appearance of traditional timber window joinery. It is vital that any decay caused by moisture penetration should be removed as soon as it is recognised. It is best to do this with thorough painting, especially if there has been damage or degradation. It is recommended to choose paints that are intended to be used in a set (primer undercoat and finish) and to follow the manufacturer’s recommendations for preparation and number of coats at each stage.

Wet rot is a typical problem for older timber windows. The best method to stop it from growing is to eliminate any damaged or rotten sections immediately to stop the spread of the fungus responsible for it. The replacement of rotting wood should be carefully undertaken using slow grown deal (pine) and, whenever feasible using the same species as that which is being removed to avoid any movement differences between the new section and the existing timbers.

Glass became more affordable and abundant during the late medieval period and into the 17th century. As a result, the glazed openings in timber-framed homes were more elaborate, with moulded mullions, tracery made of wood and deep cills projecting into the air. The glazing was increasingly laid within rebated frames and then pinned with 'glazing sprigs', rather than being inserted into lead cames. This method of glazing is not just less susceptible to leaks, but also allows for larger, clearer sheets of glass to be used in the windows than would be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness and multilayer construction as well as care for particulars. The large glass areas, the deep projecting cills and large glazing areas minimize air infiltration. With secondary glazing and draughtproofing, the windows can be improved to increase their energy efficiency. It is crucial to keep in mind that these measures should be taken into consideration when it comes to the overall integrity and look of the original windows.

Therefore, keeping old windows that require repair rather than replacing them makes sense, particularly when their thermal improvements can be achieved cost-effectively through simple repairs and improvements. Older windows are usually of historical significance, since they demonstrate a variety in technical development and changes to architectural taste. The pressures to replace these windows are generally 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 properly maintained.

It is essential to understand that the decay issues that are typical of timber windows can be avoided by thorough maintenance and prompt repairs. In addition it is crucial to recognize damp penetration issues and address them swiftly to avoid major damage. The early deterioration of paint is a particular problem, since it allows moisture penetrate the wood and cause wet rot. It is not uncommon for this issue to go undetected until the paintwork begins to crack or become wavier. However, it could cause structural damage and lead to further decay.

A paint of good quality will prevent moisture penetration. To avoid condensation and mould, it is important to keep the paintwork as clean as you can. 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 made from timber that contained a high proportion of sapwood. These timbers deteriorate quickly if exposed to rain, but they can be protected by a thorough preservation treatment before use. It is important to choose the right type of wood for your location and climate, as these factors will affect the durability of the joinery. Local window manufacturers have an array of sash made from timber that can be adapted to fit historical openings. They can be made to the standard Boston pattern dimensions or to specific dimensions that are compatible with the historic architecture.

Maintenance

The lifespan of windows made of timber can be extended considerably by regular inspection, careful redecoration and timely upvc door repair cost. The most common reason for the decay is moisture intrusion through deteriorated putty and paint. This can be avoided by using a quality wood preservative and painting the wood thoroughly.

It is essential that repairs to old sash or casement windows are well executed, and carried out with the minimum disturbance. Many traditional timber window designs are repairable without removing the frame, and this method should be taken whenever possible. Remove loose or peeling paint and lightly sand the area to improve the 'key" of the surface. This will enable the new coating to adhere better. It is essential to avoid removing old paint layers that could have historical significance.

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

Replacement of traditional windows with PVC-u can be an appealing option, particularly when the installer provides a 'one stop shop' installation that handles removal and replacement within one day. It is important that the installers of replacement windows have a deep understanding of the history and construction of traditional timber frames. This will allow them to make appropriate recommendations for energy-efficiency improvements and other technological advancements that won't alter the appearance of a historic building. Those providing replacement windows should be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are deemed to be approved under Building Regulations as a suitable option. It is quite possible for a skilled and experienced carpenter to install PVC-U windows that are sympathetic to the character of the building originally. This is especially true when windows are installed in listed buildings or conservation areas.
