It's A Sash Windows Cambridge Success Story You'll Never Believe
How to Restore Timber Sash Windows in Cambridge

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

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

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes, which are modular, can be reconstructed to their original dimensions. This allows the restoration of timber sash windows in order to meet the current energy requirements and to comply with conservation regulations for areas. It also provides windows with a more attractive appearance than uPVC alternatives.

Sliding windows with sash were initially only used for large buildings or public buildings. However the production became cheaper and artisans could create larger frames using greater glass. By the late 18th century sash windows were the dominant design of wood in the majority of British homes. As they were easy to open, sash windows let light into rooms without curtains.

The first windows were made of plain glass but by the 17th century, sash windows were becoming more attractive with coloured glass bars and moulded mullions. These were very expensive at the time, but as glass production improved and cost-effective, they became a part of many period houses.

In the 19th century, it was possible to create large, sturdy glasses that didn't require supporting bars. This allowed for the frame to be enlarged, which in turn gave the viewer a better view. This was a very important innovation.

The introduction of the double-hung sliding sash is another important improvement that was made towards the end of the I920s and the 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 common type of sash is constructed from slow-growing deal (pine) but oak was also used in more prestigious buildings and in some earlier examples. It is important to maintain the separation bead that is used to separate the sashes. This will prevent draughts and rattles. The idler wheels, sash pulleys and sash rollers are also vital to the functioning of the window.

2. Energy efficiency

As clearer and larger sheets of glass became available, sash windows began to replace hinged casements. Plate glass was placed in frames made of timber, which were secured with glazing sprigs and putty was sprayed on both sides of the frame to ensure watertightness. This type of glass gradually replaced led lights.

Sashes were introduced, which led to a greater demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights and stoppers for sashes shutter hinges and handles, and a variety of fasteners to fix the sashes. These were often decorated in motifs, inscriptions, and patterns engraved to identify the maker.

With regular maintenance, sash windows can be very energy efficient. However, if they are not maintained, they can become drafty and let in cold air. Draughts can also be caused by the deterioration of paint and putty. This issue can be fixed by using wood-to-timber products.

The industry of replacement windows is based on the perception that older windows are old and beyond repair, whereas they can be maintained with just a little care. However, repairs to these windows are costly and can cause considerable disruption to the home. Many homeowners decide to replace their windows using PVC-u from a large "one-stop shop" company for installation. 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 fitted with 'energy-saving' double glazing to achieve more energy efficient ratings than a traditional windows with sash. Double-glazed windows aren't capable of resembling the proportions and section of historic timber sashes.


3. Security

It is possible to secure traditional windows without compromising their appearance. Ironmongery, such as sash chain, mortice bolts and sash locks can be installed. These can be installed in a way so that the window is able to be opened to allow ventilation and cleaning. These are typically unobtrusive, as they are designed to match the sash window. new windows cambridge can be used in conjunction with traditional sash window catch. These should be replaced with more robust versions, such as ones that have double screws or sprung levers in order to reduce the possibility of being hammered.

Sash-window frames were made from slow-growing deal or, in more prestigious houses made of oak. Where glazing bars have survived they should be preserved, and if it is possible, the timber of the cill should be replaced by the same wood. PVC-U companies usually 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 co-ordinate various visits from different suppliers.

4. Ventilation

Sash windows were introduced in the 17th century and allowed for a large amount of light into buildings. In the 18th century, they had been modified so that more light could be let into rooms. Larger glazing panes were also made. The result was a much lighter appearance, and windows with a higher level of elegance than they had before.

Sash windows were introduced that required a brand new range ironmongery. The first pulleys were made of wood, while later Victorian ones were made from brass or a combination 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 exquisite design.

Timber windows require regular maintenance to keep them in good order. A lack of regular attention could lead to:

Sashes that do not move easily.

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

break down of the putty and allow water penetration, which could lead to decay of the frame and cill.

In the I920s and I930s, steel casement windows grew in popularity due to their strength slim and affordable and were in line with the trend for healthy living. Research has shown 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 old windows are old, dirty, and beyond 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 be.

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 deteriorating excessively. It can also cause paint and putty become damaged. The removal of sashes could also result in structural movements within the frame, causing the sash to not close properly. The sash could also get stuck in its open position, which allows the water and drafts to enter the property.

Moisture penetration is the most common cause of damage to windows made of timber. This can be avoided with regular maintenance, thorough painting and removing the cause of dampness. Wet rot is easily identified due to the wavy appearance of the existing paint which can be stripped to reveal soft, rotting timber. Any timber that is rotting must be removed and the affected area carefully wrapped or pieced back using replacements made from the same type of wood as those remaining. This method of repair increases the amount of fabric used in the first place and is among the least invasive ways to treat wood-to-timber rot.

The use of a wood consolidant made from resin is another alternative to the traditional method of sanding and staining. This is brushed onto the surface of the wood to help stabilize it and protect it from further damage. It is especially beneficial for treating pulley cords and sash which can help prevent breakage.

It is essential to preserve and not replace any historical ironmongery such as stay latches and sash latches. 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 chain stays and sash lifts is avoided if at all feasible as they could cause corrosion and deterioration of frames and sashes made of timber.
