How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have traditional sash windows and homeowners are proud of the way they look. Sash windows can get stuck and become difficult to open and close. This is usually due to moisture that can cause the timber to swell.

Traditionally, window boxes used chains or cotton cord and weights made of lead to operate. Modern sash windows come with hidden springs to address this problem.

1. Aesthetics

Timber sash windows, unlike PVC-u windows that are made in imperial sizes and are modular, can be restored to original dimensions. This lets the restoration meet the current energy standards while complying with conservation area regulations. It also offers windows that have a more attractive appearance than upvc door repair cost alternatives.

Sliding sash windows were initially only used in large structures or public buildings, though the production process became less expensive and craftsmen could produce larger frames with more glass. In the 18th century, Sash windows were the most popular wooden windows cambridge design in most British properties. Because they were simple to open, sash windows let light into rooms without curtains.

Early windows were simple glass, but by the 17th century sash windows began to become more attractive with coloured glass bars and moulded mullions. They were expensive at the beginning but as glass production became cheaper and more efficient, they became an integral feature in many historic homes.

By the 19th century it was possible to create large, strong glass that didn't require supporting bars. This allowed for the frame to be made larger which, in turn, provided an improved view. This was an important innovation.

The introduction of the double-hung sliding sash was another important improvement that occurred in the I920s and beginning of the I930s. The double-hung sliding sash was a important improvement that came into existence at the end of the I920s and at the beginning of the I930s.

The most commonly used type of sash is made from slow grown deal (pine) however oak was used in the more luxurious buildings and in some earlier examples. It is important to maintain the parting bead which separates the sashes. This will stop draughts and rattles. The idler wheels, sash pulleys and sash rollers are also essential to the functioning of the window.

2. Energy efficiency

As larger and clearer sheets of glass became available, sash window began to replace hinged casements. They were coated with plate glass that was set in timber frames with rebates and secured with glazing sprigs and putty on both sides to ensure they were watertight. This kind of glass gradually replaced led lights.

The introduction of sashes created a need for a much larger variety of ironmongery including the most basic fittings, brass pulleys, lead (and later cast iron) weights, sash stoppers, shutter hinges and knobs as well as a range of fasteners to hold the sashes in place. They were often decorated with designs, inscriptions, and engravings to identify the maker.

With regular maintenance, sash windows can be extremely energy efficient. If they are not maintained, they can become draughty. Draughts can also be caused by the deterioration of putty and paint. You can fix this problem by using wood-to-timber solutions.

The industry of replacement windows relies heavily on the notion that old windows are beyond repair and therefore cannot be maintained economically. However windows can be easily maintained with a bit of attention. Repairs can be costly and cause lots of disruption to the home. To avoid this, many homeowners opt for a complete replacement with PVC-u windows from one of the large "one-stop shop" installation companies. They can replace all windows in a house in a single day, saving time and avoiding the need for multiple tradesmen to coordinate. These windows can be fitted with 'energy-saving double-glazing to attain higher energy ratings than the traditional windows made of sash. However, these double glazing cambridge-glazed units cannot replicate the section and proportions of traditional timber sashes.

3. Security

Traditional windows can be secured without compromising their aesthetics. Ironmongery such as mortice bolts, sash chain and sash lock could be installed. These can be installed so that the window and door repair near me is capable of being opened for ventilation or cleaning. They are usually not noticeable since they are designed to complement sash windows. They can be used with traditional sash window catch. They should be replaced by more robust models, such as those with double glazing repairs screws, or sprung levers, to minimize the possibility of being hammered.

Sash-window frames are traditionally made from oak or slow-grown deal. If the glazing bars are intact and in good condition, they should be kept. Where feasible, the cills made of timber should be replaced by timber that is compatible with. PVC-u companies typically provide a one-stop shop installation service, which includes removing and replacing windows on an entire home in a single day without the need to engage other tradespeople or co-ordinate various visits from different suppliers.

4. Ventilation

When sash windows were first introduced in the 17th century, they allowed a large amount of light into the buildings. By the end 18th century, they were adapted so that even more light could be let into rooms. Larger glass panes were also created. The result was a lighter look and windows with more elegance.

Sash windows were introduced, which required a new type of ironmongery. The first pulleys were made of wood, whereas later Victorian ones were made from brass or a mixture of lead and wood and there were a variety of shutter hinges and knobs. These ironmongery pieces must be kept clean and preserved in order to appreciate their fine design.

Timber windows require careful maintenance to keep them in good condition. Lack of attention to them regularly could lead to:

sashes that no longer slide easily.

Holes in the frame which allow water to enter and cause damage and decay.

Water can penetrate the putty and cause decay to the frame or the cill.

Steel casement windows were popular in the I920s & I930s because they were strong and slim, cheap and complemented the trend for healthy living. Research has proven that softwood sash windows are as efficient as PVC-u windows, and may even be more attractive.

The industry of replacement windows has done a lot to convince homeowners that their windows are old, dirty, and beyond economic repair. The truth is that a lot of older windows made of wood are in good condition and with minor repairs can easily be maintained for years to be.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. Inability to maintain it properly could result in the sash cords breaking, a lot of wear on the glazing bars, and degradation of the paint and putty. The removal of sashes may also cause structural shifts within the frame, which causes the sash to move out of alignment and not closing properly. It is also possible for the sash be stuck or fixed in an open position, which can let water and draughts enter the property.

The damage to timber windows is often caused by water penetration. This can be prevented by careful painting, regular repairs and elimination of the source of dampness. The paint can be removed to reveal the soft, rotting wood. Any rotten sections of timber should be cut out and the affected part carefully scarfed or pieced in using replacements made of the same kind of timber as those remaining. This method of repair increases the amount of original fabric left, and is among the least invasive ways of treating decay caused by timber.

The use of a wood consolidant made from resin is an alternative to the traditional method of staining and sanding. It is brushed on the surface of the wood to stabilize it and shield it from further damage. It is particularly useful for the treatment of sash cords and pulleys which help prevent breakage.

It is essential to preserve and not replace any old ironmongery, like stay latches and sash latches. They can be extremely difficult to replace without compromising the the original design. It is recommended that the use of modern aluminum fittings like sash lifts and chain stays is avoided if at all possible as they can cause corrosion and deterioration of frames and sashes made of timber.
