Glass-Replacement-150x150.jpgMany 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.

Box sash windows were historically operated using chains, cotton cords and lead weights. Modern window springs for sash windows are concealed to eliminate this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes that are modular, can be restored to their original dimensions. This allows the restoration to meet modern day energy requirements while ensuring compliance with conservation areas regulations. It also gives windows with a superior appearance than upvc door repair alternatives.

Sliding sash windows were originally only used in large structures or public buildings, but this changed as production became less expensive and craftsmen could make larger frames with more glass. In the late 18th century windows made of sash were the predominant design of wood in the majority of British homes. As they were easy to open sash windows allowed light into rooms without the need for curtains.

The first windows were made of plain glass but by the 17th century, sash windows started to become more decorative with coloured glazing bars and moulded mullions. These windows were quite expensive at the time but as glass production became more efficient and less expensive, they were a common feature in many of the period homes.

In the 19th century, it was possible to produce large, sturdy glasses that didn't require supporting bars. This allowed the frame to be made bigger and, in turn, gave the viewer a better view. This was an important innovation.

The introduction of the double-hung sliding sash is another important improvement that occurred towards the end of the I920s and at the beginning of the I930s. This allowed both the upper and lower sash to be opened simultaneously and gave improved ventilation to buildings.

Oak was used in older and more luxurious buildings. A parting bead separates the two sashes and it is essential that it is well maintained to prevent rattles and draughts. It is also crucial that sash pulleys and idler wheels are in good shape as they assist in operating the window.

2. Energy efficiency

As clearer and larger sheets of glass became available, sash window started replacing hinged casements. They were made of plate glass, set in timber frames with rebates and pinned in place using glazing sprigs, with putty on both sides to ensure they were watertight. This type of glazing gradually replaced leaded lights.

The introduction of sashes led to the need for a greater variety of ironmongery, with the most basic fittings being brass pulleys and lead (and later cast iron) weights, sash stoppers shutter hinges and knobs and a variety of fasteners used to keep the sashes in place. They were often decorated with patterns, inscriptions and engravings to identify the maker.

With regular maintenance, sash windows are extremely energy efficient. If they are not maintained they could become noisy. Paint and putty can also cause draughts. It is possible to fix this issue by using wood-to-timber solutions.

The industry of replacement windows relies heavily on the perception that older windows are beyond repair and are not able to be maintained economically. However, they can easily be maintained with a little attention. These repairs can be costly and cause a lot of disruption in the home. Many homeowners opt to replace their windows with PVC-u from a 'one-stop shop' installation company. They can replace all windows in a house in one day, saving time and avoiding the need for different tradesmen to coordinate. They can also be supplied with 'energy-saving' double-glazing, which can achieve more energy efficient ratings than those offered by traditional sash windows. However, these double-glazed units cannot duplicate the proportions and section of traditional timber sashes.

3. Security

It is possible to secure windows that are traditional without compromising their style. Ironmongery, such as sash chain, mortice bolts, and sash lock can be used. They can be positioned in such a way that the window can be opened to allow ventilation and cleaning. They are usually unobtrusive as they are designed to complement sash windows. They can be used in conjunction with traditional sash window catches and are required to be replaced with more robust models (such as those incorporating double screws) or sprung levers to reduce the possibility of them being hammered out.

Sash-window frames are usually constructed from oak or slow-grown deal. If the glazing bars remain intact, they should be retained. If feasible, the cills made of timber should be replaced with timber that is compatible with. Many PVC-U firms offer a one-stop installation service. They can remove and replace windows on an entire house in just one day, without the need to involve other tradespeople.

4. Ventilation

When sash windows were first introduced in the 17th century they allowed a substantial amount of light into structures. By the end of the 18th century, they were adapted to allow more light into rooms and larger glass panes began to be manufactured. The result was a much lighter appearance, and windows that had a higher quality of design than before.

Sash windows were introduced that required a brand new type of ironmongery. Early pulleys were constructed out of wood. Later Victorian ones were made of brass or a mixture of wood and lead. There were also a variety of types of shutter hinges and knobs. These ironmongery pieces must be maintained and cleaned to appreciate their fine design.

Timber windows require regular maintenance to ensure they remain in good condition. A lack of regular attention could lead to:

Sashes that no longer slide smoothly.

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

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

Steel casement windows became popular in the I920s and I930s due to their strength and slim, and also because they were 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 windows made of PVC-u, and are more attractive than the sleek lines of modern casement wooden windows cambridge (just click the next web page).

The window replacement industry has made a significant effort to persuade house owners that their old windows are rotten, draughty and beyond economic repair. Many old windows made of timber are repairable and can be used for many more years with minor repairs.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. If you do not maintain your window's sash, it could lead to the sash cords breaking and the glazing bars wearing out excessively. It could also cause the paint and putty to become damaged. The removal of the sashes could also result in structural movement within the frame which causes the sash to move out of alignment and in a position that it is not able to close properly. It is also possible for the sash be snagged or slammed into an open position and let water and draughts enter the structure.

Moisture penetration is the most common cause of damage to timber windows. This can be avoided with regular maintenance by thorough painting and eliminating the cause of dampness. Wet rot can be identified due to the wavy appearance of the existing paint which can be stripped away to reveal soft, rotting timber. The sections of timber that are rotten should be carefully removed, and the affected area should be snared together or glued together using replacements of the same nature as the rest of the timber. This method of repair increases 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 wood consolidant made from resin is another alternative to the traditional method of sanding and staining. It is brushed on the surface of the wood to help stabilize it and shield it from further damage. It is especially useful for the treatment of pulley cords and sash, which can stop breakage.

It is important that any old ironmongery like sash stays and latches are retained and rehabilitated instead of being replaced. They can be extremely difficult to replace without compromising the quality of the original design. It is also advised that modern aluminium fittings like sashlifts, as well as chainstays, are avoided since they could cause corrosion and deterioration of timber frames and sashes.
