Maintaining Timber Windows

A well-maintained wooden window is an important component of a historical building. It reflects in different degree the materials and technologies of the time period it was constructed, the craftsmanship and architectural taste.

Whenever possible upvc door repairs to existing windows should be done in-situ. Repairing the worst areas of decay can be done by using specialized resin-based systems.

Durability

Timber windows were built to last hundreds of years. They do require some maintenance to keep them looking good. Maintenance tasks include repairs to sash cables as well as tightening the sash pulleys and painting. The demand for enhancing timber windows to increase efficiency and energy efficiency is also increasing. This can include replacing old Cambridge Double Glazing units, fixing existing window rebates or installing new cills to increase the air seal.

A key problem with traditional windows is the damage caused by corrosion of the paintwork. This is especially important when it comes to sash windows, as the gaps between sashes can often be extremely large. In these cases water can enter the paint film and cause rotting of the wood or putty underneath. Poor weather conditions can exacerbate the rotting. To stop this from happening, windows should be painted regularly using a suitable exterior wood paint.

The areas that are damaged should also be repaired using resin-based products. This will ensure that the greatest amount of original fabric preserved. It is also essential to limit the number of holes you drill into the frame to allow cable entry as these can admit water and lead to decay.

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

There are a variety of companies that make Boston pattern wooden sash to fit into the majority of existing openings. The sash is available in a variety of sizes and finishes to meet the needs of today's homeowner. The new sash, combined with quadruple draft strip and a more efficient thermal insulation, could make a significant difference to the energy-efficiency of a home.

Aesthetics

Many old timber frames have a high aesthetic appeal, as they reflect, in some form, the materials technology, the construction process, and the architectural aesthetics of the time they were constructed. They may have significant historical significance on their own. This is particularly true of early windows that were not glazed in timber framed buildings where the great majority were just a collection of openings in the frame that were subdivided 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 essential that any decay caused by water penetration is stopped as soon as it is recognised. This is best accomplished by a thorough painting process, especially in areas where there has already been damage or deterioration. It is advisable to use paints designed to be used as part of a system (primer undercoat, finish) and follow the manufacturer's guidelines in terms of preparation and the number of coats required at each stage.

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

In the late the 17th and early the medieval periods, glass became less expensive and more abundant, and the openings for glazed glass in timber-framed buildings gradually became elegant with wooden tracery moulded mullions, moulded mullions, and deep protruding cills. Increasingly, the glazing was laid within rebated frames and then pinned with 'glazing sprigs' rather than into lead cames. This method of glazing is not only less susceptible to leaks, but also allows for much wider clearer, more transparent sheets of glass to be used in the windows than would be possible without the need for lead lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness and multilayer construction, as well as their care for the smallest of details. They also feature large glass areas and projecting cills that minimise air infiltration. The windows can be modified to improve their energy efficiency by draught-proofing and secondary glazing. It is important to remember that these measures need to be considered in relation to the overall integrity and appearance of the original windows.

It is sensible to repair or upgrade existing windows that are older rather than replacing them, particularly when improvement in thermal efficiency can be achieved through simple fixes. Older windows typically have a historical value that shows a variety of technological advances and changes in architectural taste. Most people assume that these windows will have to be replaced in the near future. However, most will last for 150,200, and even 250 years with proper maintenance.

It is important to recognize that decay issues in traditional timber windows are easily prevented with quick and thorough upvc door handle repairs near me. Additionally, it is essential to recognize damp penetration issues and fix them promptly to prevent serious damage. Paint deterioration that occurs early could be a problem as it allows moisture to penetrate into the wood, which can cause wet rot. It is not uncommon for this type of damage to go undetected until the paintwork starts to crack or turn curly. However, it could cause structural damage and then further decay.

A good quality paint will prevent this moisture from entering. To prevent mould and condensation it is crucial to keep the paintwork as clean as possible. Modern synthetic paints can be problematic, as they are often designed to be water-resistant and this can cause the growth of mildew inside the window frame.

The majority of windows from the past were constructed from timber with an extensive proportion of sapwood. The timbers will deteriorate rapidly if exposed to wet weather, however they can be protected with a thorough preservative treatment before they are put to use. It is essential to select the right type of wood for the site and climate, as these variables will affect the durability of the joinery. Local window seal repairs manufacturers create various types of timber sash that can be tailored to fit specific openings in historic buildings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to historical structures.

Maintenance

The life of timber double glazed windows cambridge windows can be extended significantly by regular inspection as well as a careful redecoration and timely repair. The major cause of decay is moisture leaking through deteriorated paint or putty. This can be avoided by thorough painting and using a good quality wood preservative.

It is important that repairs to old sash or casement windows are properly executed and done without causing any disturbance. Many of the traditional designs for timber windows can be repaired without removing the frame, and this method should be followed whenever possible. Paint that is peeling or loose must be removed with care and sanded lightly to improve the key of the surface and facilitate a better adhesion of the new coating. It is important to not remove old paint layers, as they may have historical value.

If a piece of wood has rotted the best option is to remove it and replace it with timber inserts shaped to match existing profiles. The wood that is being inserted should be treated with wood preservative, and the junction between the timber cill and the sub-cill for masonry should be sealed.

It's tempting to replace traditional windows with PVC U, particularly when the installer offers an 'all-in-one' installation which includes both removal and replacement in a single day. It is, however, essential that the person installing windows replacement has a thorough knowledge of the construction and history of traditional timber frames. This will allow them to make the appropriate recommendations for energy efficiency improvements and other technical upgrades that will not harm the historic character of a building. Anyone who installs replacement windows should be registered with a Competent Persons Scheme, such as FENSA. This will ensure the replacements are approved under Building Regulations as a suitable option. It is, of course, possible for an experienced and skilled carpenter to install PVC-U windows that match the character of the original building. This is especially applicable when windows are situated within listed buildings or conservation areas.
