Whenever possible repairs to existing windows are required, they should be made in-situ. Repair systems made of resin can be used to fix the worst areas of decay without removing the whole window.

Durability

The timber windows in many historic structures were designed to last for a long time. However, they do need to be maintained to keep them looking good and operating properly. The most frequent maintenance tasks include repairs to sash cords as well as tightening sash pulleys and painting. The demand for upgrading windows made of timber to increase efficiency and energy efficiency is also increasing. This may mean replacing old glass units, fixing the window repair cambridge rebates that are in place, or installing new cills for better air sealing.

The corrosion of paintwork is a major issue with traditional windows. This is particularly important when sash windows are involved as the gaps between the sashes can be quite large. In these instances water can get into the paint film and cause decay of the putty and the wood underneath. Poor weather conditions can exacerbate the rotting. To prevent this from happening, windows need to be regularly painted with an exterior wood paint.

In addition to repainting, areas that have corroded need to be repaired with an adhesive-based repair product. This will ensure the maximum amount of the original fabric is preserved. It is crucial to reduce the number of holes that are drilled in the frame to allow cable entry, as these can admit moisture and cause decay.

Another major issue with older windows is the structural movement within the wall that can cause deformation of the frame and sash. This can result in sash no longer fitting correctly or sticking or jamming into the opening, and damaged glazing. Most often, this is corrected by the fitting of new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill should be constructed from a sturdy hardwood, like oak, to avoid differential movement between new and existing work.

There are several companies that produce Boston pattern wooden sash to fit in with the majority of openings. They are available in a variety of sizes and finishes to meet the requirements of the modern homeowner. The new sash, coupled with quadruple draft strips and improved thermal insulation can make a significant difference to the efficiency of a home's energy use.

Aesthetics

A lot of old timber frames have a great aesthetic appeal, since they show, in some shape, the materials technology, the construction process, and the architectural aesthetics of the time they were built. They could have significant historical value as a set. This is especially true of early unglazed windows in timber-framed structures, where the majority of them were series openings in frames of structural construction, which were divided horizontally by mullions, and vertically by wood or iron bars to protect against intruders.

Traditional window joinery made from timber is a beautiful element of a structure and it is important to keep it looking good. When you spot any signs of decay due to the penetration of moisture, it is important to stop it.

It is recommended to use paints specifically designed to be used as part of the system (primer, undercoat and finish) and follow the manufacturer's guidelines regarding preparation and the amount of coats required at each stage.

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

In the late medieval and 17th century periods glass became cheaper and more plentiful so that glazed openings in timber-framed structures gradually became more elegant with wooden tracery as well as moulded mullions and protruding cills. In recent years, glazing was fixed to frames that were rebated with glazing sprigs rather than lead cames. This method of glazing not only makes the windows less likely to leak and break, but also allows larger sheets of glass to be utilized than would have been feasible without the use of lead lights.

Energy efficiency

Traditional timber windows have excellent energy efficiency due to their thickness and multi-layer construction, as well as meticulous attention to detail. They also have large glass areas and deep projection cills which reduce air infiltration. With secondary glazing and draught proofing, windows can be upgraded to improve their energy efficiency. It is essential to keep in mind that these measures must be considered in relation to the overall integrity and look of the original windows.

It is sensible to fix or upgrade windows that are older rather than replacing them, particularly when improvement in energy efficiency can be made by simple repairs. Historic windows often have an historic value that shows a variety of technical development and changes in architectural tastes. Most people assume that the windows will need to be replaced in the near future. However, most will last for 150, 200 or even 250 years with proper maintenance.

It is also essential to identify damp problems and fix them quickly so that you can avoid 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 damage to go undetected until the paintwork starts to crack or turn wavier. However, it could cause structural damage and lead to further decay.

A paint of good quality will stop moisture from entering the paint. To prevent mould and condensation it is crucial to keep the paintwork as clean as it can be. Modern synthetic paints can pose a problem because they are usually designed 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 made from timber that contained an extensive proportion of sapwood. The timbers will deteriorate rapidly if exposed to wet weather, but can be preserved with a thorough preservative treatment before they are put to use. It is also essential to ensure that the kind of timber used is well-suited to the climate and site conditions, as these elements affect the durability of the joinery. Local window manufacturers create various types of timber sash that can be adapted to fit specific historic openings. They are available in the standard Boston pattern or in custom sizes to fit the architectural style of historic structures.

Maintenance
