How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and homeowners are proud of the way they appear. However, sash windows may get stuck and be difficult to open or close. This is often due moisture which can cause the timber to expand.

Traditionally, box sash windows utilized chains, cotton cords or lead weights to operate. Modern sash windows have hidden springs to solve this problem.

1. Aesthetics

Contrary to PVC-u windows which are constructed according to the modular imperial size, timber sash windows can be restored to their original dimensions. This allows the restoration to meet modern day energy requirements while ensuring compliance with conservation regulations for the area. It also offers a window doctor cambridge that is far superior to upvc doors repairs alternatives.

Sliding sash windows were initially only found in large buildings or public buildings, but the production process was less expensive and craftsmen were able to make larger frames with more glass. In the late 18th century windows made of sash were the predominant wooden style in a majority of British properties. As they were easy to open, sash windows let light into rooms without the need for curtains.

The first windows were made of plain glass However, in the 17th century the sash windows began to be more decorative. They began with colored glazing bars or mullions. They were costly at first, but as glass production became less expensive and more efficient, they became an integral feature in many historic homes.

In the 19th century it was possible to create large, sturdy glass that did not need supporting bars. This allowed for the frame to be made larger which, in turn, provided a better view. This was an important innovation.

The introduction of the double-hung sliding sash was another important improvement that was made towards the end of the I920s and beginning of the I930s. The double-hung sliding sash was a significant improvement that came about at the end of the I920s and at the beginning of the I930s.

The most popular type of sash is constructed from slow grown deal (pine) but oak was utilized in more luxurious buildings and in earlier examples. It is important to maintain the parting bead which separates the sashes. This will help prevent draughts and rattles. The idler wheels, sash pulleys and sash rollers also are vital for the proper operation of the soundproof window repair.

2. Energy efficiency

As larger and clearer glass sheets were made available, sash windows started replacing hinged casements. Glass plates were set in frames of timber that were rebated, then which were pinned with glazing sprigs, and putty was applied to the frame's two sides for watertightness. This kind of glazing gradually replaced leaded lights.

The introduction of sashes resulted in the need for a larger variety of ironmongery with the basic fittings being brass pulleys and lead (and later cast iron) weights, sash stoppers, shutter hinges and knobs as well as a range of fasteners that secured the sashes in place. These were often decorated in designs, inscriptions, and patterns engraved to identify the maker.

Sash windows can be extremely energy efficient if they are maintained regularly. If they are not maintained they can get noisy. Putty and paint can cause draughts. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The replacement window industry relies on the belief that old windows are damaged and beyond repair, while they can be easily maintained with just a little care. Repairs can be expensive and cause a lot of disruption in the home. To avoid this homeowners often choose to replace their windows with PVC-u windows from one the large "one-stop shop" installation companies. They can replace all windows in a home in a single day, saving time and eliminating the need for multiple tradesmen to coordinate. They are also available with 'energy-saving' double-glazing to achieve greater energy efficiency than are possible with traditional sash windows. However, these double-glazed units cannot duplicate the proportions and section of traditional timber sashes.

3. Security

Traditional windows can be made secure without compromising their style. Ironmongery, such as sash chain, mortice bolts and sash locks can be installed. They can be positioned in such a way that the window is able to be opened for ventilation and cleaning. They are usually unobtrusive as they are designed to complement sash windows. They can be used with traditional sash window catch. These should be replaced by more robust versions, such as those with double screws, or sprung levers, to minimize the chance of being hammered.

Sash-window frames are traditionally made of oak or slow-grown deal. If the glazing bars are in good condition and are not damaged, they should be left. If it is feasible, the cills made of timber should be replaced with wood that is in line with. PVC-u companies typically provide a one-stop shop installation service, which includes removing and replacing windows on a complete home in one day, without the need to involve other tradespeople, or coordinate visits from a number of different suppliers.

4. Ventilation

When sash windows were first introduced in the 17th century they allowed a large amount of light to flood into buildings. By the end of the 18th century, they were altered to allow even more light into rooms, and bigger glazing panes started to be made. The result was a lighter look and windows with more elegance.

The introduction of sash windows also required a new range of ironmongery. Early pulleys could be made from wood. Later Victorian ones were made of brass or a mix of wood and lead. There were also various kinds of knobs and shutter hinges. The ironmongery pieces need to be cleaned and preserved to appreciate their beautiful design.

To ensure they remain in good condition, wooden windows need to be maintained. Inattention to maintenance routinely could lead to:

Sashes that do not slide easily.

holes in the frame allow water, which can cause damage and decay.

break down of putty, allowing water penetration that can lead to decay in the frame and cill.

In the I920s and I930s, steel casement windows grew in popularity due to their durability, slim and cheap, and complemented the vogue for healthy living. However, research has proven that traditional softwood sash windows are as efficient in thermal efficiency as double-glazed PVC-u windows and may be more appealing than the modern sleek design of casement windows.

The industry of replacement windows has made a significant effort to persuade house owners that their windows are old, dirty, and beyond economic repair. Many older timber windows can be repaired and utilized for a longer period with minor repairs.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. If you fail to maintain your sash window, it can cause the sash cords breaking, and the glazing bars wearing out excessively. It can also cause paint and putty to deteriorate. The removal of sashes can also result in structural movement within the frame, which can cause the sash not to close properly. It is also possible for the sash be snagged or fixed in an open position, which can let water and draughts in the structure.

Moisture penetration is a common cause of damage to timber windows. This can be prevented by thorough painting, regular repairs and the elimination of the source of dampness. The paint can be removed to expose the soft, decaying wood. Any rotten sections of timber must be removed and the affected area carefully wrapped or pieced back using replacements made from the same kind of timber as the ones remaining. This method of repair maximizes the amount of fabric used in the first place and is among the most minimally invasive methods of treating timber-to-timber rot.

The use of a resin-based wood consolidant is another alternative to traditional sanding and staining. This is brushed onto the surface of the wood to stabilize it and protect it from further damage. It is particularly useful for treating sash and pulley cords, where it can prevent breakage.

It is crucial to restore and not replace any old ironmongery, like the sash latches and stays. It can be difficult to replace these items without altering their original design. It is also recommended that the use of modern aluminum fittings such as sash lifts and chain stays is avoided whenever possible as they can cause corrosion and damage to frames and sashes made of timber.
