The Underrated Companies To Watch In Sash Windows Cambridge Industry

Many homes in Cambridge feature traditional sash window and homeowners are proud of their appearance. Sash windows can become stuck and become difficult to open or shut. This is usually due moisture, which can cause the wood to expand.
Box sash windows were historically operated by chains, cotton cords and weights made of lead. Modern sash windows come with hidden springs to solve this problem.
1. Aesthetics
Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes that are modular, are able to be restored to original dimensions. This allows the restoration to meet modern day energy requirements while complying with conservation area regulations. It also comes with windows that are superior to the upvc window lock repair alternatives.
Sliding sash windows were initially only used in large structures or public buildings, but the production process became cheaper and craftsmen could produce larger frames with more glass. At the end of the 18th century, sash windows had become the most popular wooden style in British homes. As they were easy to open, sash windows let light into rooms without the need for curtains.
Early windows were plain glass, but by the 17th century sash windows were becoming 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 cost-effective, they became a part of many of the period homes.
By the 19th century it was possible to create large, strong glass that didn't require supporting bars. This allowed the frame size to be enlarged further, which allowed for a wider view out of the window. This was a significant advancement.
The introduction of the double-hung sliding sash is another important improvement that was made at the end of the I920s and beginning of the I930s. This allowed both the lower and upper sash to be opened at the same time and gave improved ventilation to buildings.
The most commonly used type of sash is constructed of slow-growing deal (pine) but oak was utilized in more luxurious buildings and in earlier examples. It is important to maintain the parting bead that separates the sashes. This will prevent draughts and rattles. The idler wheels, sash pulleys and sash rollers are essential to the operation of the window.
2. Energy efficiency
Sash windows were replaced by hinged casements as clearer and larger sheets became available. They were made of plate glass, set in timber frames with rebates and then pinned with glazing sprigs, with putty on both sides to ensure they were watertight. This kind of glass gradually replaced leaded lights.
Sashes were introduced, which resulted in a greater demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights as well as sash stoppers shutter hinges and handles and a variety of fasteners to fix the sashes. These were often decorated with motifs, inscriptions or engraved patterns that identified the maker.
With regular maintenance, sash windows are very energy efficient. However, if they are not maintained, they can become drafty and let in cold air. Draughts can also result from the degeneration of paint and putty. This issue can be fixed with wood-to-timber products.
The industry of replacement windows relies heavily on the notion that older windows are beyond repair and cannot be maintained economically. However windows can be easily maintained with a little attention. However, these repairs can be costly and cause substantial disruption to the home. To prevent this homeowners, many opt for a complete replacement with PVC-u windows from one of the largest "one-stop shop" installation companies. They can replace all windows in a home in one day, saving time and avoiding the need for different tradesmen to coordinate. They are also available with 'energy-saving' double-glazing, which can achieve more energy efficient ratings than traditional windows with sash. However, these double-glazed units cannot replicate the section and proportions of the sashes made of timber from the past.
3. Security
It is possible to secure windows that are traditional without compromising their style. There are many types of ironmongery that can be fitted, including sash chains, mortice bolts and sash locks. These can be installed in a way so that the window can be opened for ventilation and cleaning. These are typically not noticeable, since they are designed to complement the sash window. They can be used in conjunction with traditional sash-window catchers that must be replaced by more robust models (such ones that have double screws) or spring levers to decrease the chance of them being opened by hammering.
Sash-window frames are traditionally made of oak or slow-grown deal. When glazing bars have survived they should be preserved, and, if it is possible, the timber of the cill should be replaced by identical wood. PVC-U companies usually provide a one-stop shop installation service, removing and replacing windows on a complete home in one 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 huge amount of light to be absorbed into buildings. By the end of the 18th century, they were altered to allow more light into rooms and bigger glazing panes started to be produced. The result was a lighter appearance and windows with more elegance.
The introduction of sash windows also required an entirely new range of ironmongery. Early pulleys were constructed from wood. Later Victorian ones were made of brass or a combination of wood and leaded. There were also various types of shutter hinges and knobs. The ironmongery components should be retained and cleaned down so that the fine quality of their design can be appreciated.
Timber windows require careful maintenance to keep them in good order. Inattention to maintenance can lead to:
Sashes that do not slide smoothly.
holes in the frame that allow water that can cause decay and damage.
break down of putty, allowing water penetration, which could lead to decay of the frame and cill.
In the I920s and I930s, steel casement windows increased in popularity due to their strength, slim and cheap, and complemented the vogue for healthy living. However, research has shown that traditional softwood sash windows are just as efficient thermally as double-glazed windows made of PVC-u, and may be more appealing than the modern sleek design of casement windows.
The replacement window industry has done a lot to persuade house owners that their old windows are rotten, draughty and beyond economic repair. The truth is that a lot of older windows made of timber are in good condition and with minor repairs could easily be repaired for many years to come.
5. Maintenance
The traditional sash windows need regular maintenance and inspection. If you fail to maintain your window's sash, it could cause the sash cords breaking, and the glazing bars deteriorating excessively. It can also cause paint and putty deteriorate. The removal of sashes can also result in structural movement within the frame which causes the sash to become misaligned and in a position that it is not able to close properly. The sash can also be stuck in its open position, which allows the water and drafts to enter the property.
The damage to timber windows is often caused by water penetration. This can be prevented by thorough painting, regular upvc door handle repairs near me and the elimination of the source of dampness. The paint can be removed to expose the soft, rotting wood. The sections that are rotting should be carefully cut out, and the affected area should be scarfed together or pieced together with replacements of the exact nature as the rest of the timber. This method of repair maximizes the amount of original fabric retained and is one of the least invasive methods for treating timber-to-timber decay.
A resin-based wood condenser is a viable alternative to traditional staining or sanding. The product is brushed on the surface of the wood to protect it and stabilise it. It is particularly useful for the treatment of sash and pulley cords, which can stop breakage.
It is essential to preserve and not replace any historical ironmongery, such as stay latches and sash latches. These items can be very difficult to replace without damaging the quality of the original design. It is also advised that modern aluminium fittings like sashlifts and chainstays, be avoided as they could cause corrosion and deterioration of timber frames and sashes.
