How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have traditional sash windows and homeowners are proud of their appearance. However, sash windows can get stuck and be difficult to open or close. This is usually due moisture which can cause the wood to expand.

Traditionally, windows made of box sash utilized chains or cotton cord and weights made of lead to operate. Modern window springs for sash windows are concealed to solve this problem.

1. Aesthetics

Contrary to PVC-u windows which are manufactured according to the modular imperial size the timber sash windows are able to be restored to their original sizes. This allows the restoration of timber sash windows to comply with current energy standards and comply with conservation area regulations. It also provides a window doctor near me with a far superior appearance than the upvc window renovation alternatives.

Sliding sash windows were originally only used in large buildings or public buildings, however this changed when production became less expensive and craftsmen could create larger frames using more glass. In the 18th century, windows made of sash were the predominant design of wood in the majority of British properties. Because they were simple to open, sash windows let light into rooms without the need for curtains.

The first windows were made of plain glass, but in the 17th century, sash windows began to become more ornamental. They were initially made of colored glazing bars, also known as mullions. They were expensive initially, but when glass production became less expensive and more efficient, they became commonplace in many homes of the period.

In the 19th century, it was possible to make large, strong glass that didn't require supporting bars. This allowed for the frame to be made larger and, in turn, gave the viewer a better view. This was a significant innovation.

Another significant improvement was the introduction of the double-hung sliding Childproof window repair at the end of I920s and at the beginning of the I930s. This allowed both the upper and lower sash to be opened simultaneously and also improved the ventilation of a building.

Oak was used in older examples and more prestigious buildings. It is important to maintain the parting bead that separates the sashes. This will stop draughts and rattles. The sash pulleys, idler wheels and sash rollers are vital to the operation of the upvc window lock repair.

2. Energy efficiency

Sash windows were replaced by hinged casements as clearer and larger sheets were made available. Plate glass was placed in frames of timber that were rebated, then pinned with glazing sprigs and putty was applied to the frame's sides to ensure watertightness. This kind of glazing gradually replaced the leaded light bulbs.

Sashes were introduced, which resulted in an increase in demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges, handles and shutter hinges as well as various fasteners used to secure the sashes. These were often decorated in designs, inscriptions, and engraved patterns to identify the maker.

With regular maintenance, sash windows can be very energy efficient. Without this maintenance, 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 belief that old windows are beyond repair and cannot be maintained economically. However they can be maintained with a little attention. Repairs can be costly and cause many disruptions in the home. To prevent this, many homeowners choose to replace their windows with PVC-u windows from one of the largest "one-stop shop" installation companies. They can replace all windows in a house in a single day, saving time and eliminating the need for multiple tradesmen to coordinate. These windows can be equipped with energy-saving double glazing repairs cambridge-glazing to attain higher energy ratings than the traditional windows made of sash. However double-glazed windows cannot duplicate the proportions and section of the sashes made of timber from the past.

3. Security

Traditional windows can be made more secure without compromising their appearance. Ironmongery such as mortice bolts, sash chain and sash lock could be installed. These can be put in place so that the window is still open to allow ventilation or for cleaning. These products are often discrete since they are made to complement sash windows. They can be used with traditional sash window catch. These should be replaced by more robust versions like those that incorporate double screws, or sprung levers to decrease the possibility of being hammered.

Sash-window frames are typically constructed from oak or slow-grown deal. When glazing bars have survived they should be kept, and, if possible, the timber of the cill should be replaced by identical wood. PVC-u companies typically offer a one stop shop installation service, removing and replacing windows on an entire home in a single day without the need to engage other tradespeople or coordinate visits from a number of different suppliers.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a significant amount of light to enter buildings. By the end 18th century, they were modified to allow more light could be let into the rooms. Larger glass panes were also created. The result was a more streamlined appearance, and windows with a higher quality of design than before.

The introduction of sash windows also required the creation of a new line of ironmongery. Early pulleys were made from wood, while later Victorian ones could be made of brass or a mixture of lead and wood and there were various types of shutter hinges and knobs. These ironmongery elements should always be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

Timber windows require careful maintenance to ensure they remain in good order. Lack of attention to them regularly can result in:

Sashes that don't slide smoothly.

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

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

Steel casement windows became popular in the I920s & I930s because they were sturdy and slim, cheap and complemented the trend for healthy living. However, research has shown that traditional softwood sash windows are just as thermally efficient as double-glazed PVC-u windows and may be more appealing than the sleek lines of contemporary casement windows.

The window replacement industry has made a significant effort to convince homeowners that their traditional windows are rotten, draughty and beyond economic repair. The truth is that a lot of old windows made of wood are in good condition and, with minor repairs, could easily be maintained for years to be.

5. Maintenance

Traditional sash windows require regular maintenance and inspection. Inability to keep up with this can result in broken sash cords, excessive wear on the glazing bars, and the deterioration of putty and paint. The removal of sashes can also cause structural movement in the frame, causing the sash to not close properly. It is also possible for the sash to be snagged or fixed in an open position and let water and draughts enter the property.

Moisture penetration is the most common cause of damage to windows made of timber. This can be avoided by regular repairs by thorough painting and eliminating the source of dampness. Wet rot can be identified by the wavy appearance of the paint, which can be stripped away to reveal soft, rotting wood. Any rotten timber sections should be cut off and the affected area should be carefully wrapped or pieced back using replacements made from the same kind of timber as the ones remaining. This repair method increases the amount of fabric that was originally used and is one of most non-invasive methods to treat wood-to-timber rot.

A wood condenser made of resin is an alternative to the traditional process of sanding or staining. The product is brushed on to the surface of the wood to help stabilize it and shield it from further damage. It is especially beneficial for the treatment of sash and pulley cords, which can help prevent breakage.

It is important to restore and not replace any old ironmongery, such as stay latches and sash latches. It can be difficult to replace these items without altering their original design. It is also advised that modern fittings made of aluminium, such as sashlifts and chainstays, are avoided since they can cause corrosion and deterioration of timber frames and sashes.
