How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and homeowners are proud of the way they appear. However, sash windows can get stuck and be difficult to open or close. This is often due to moisture which can cause the timber to swell.

Traditionally, window boxes utilised chains or cotton cords and weights made of lead to operate. Modern sash window springs are hidden to eliminate this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes and are modular, can be restored to original dimensions. This allows for the restoration of timber sash windows in order to meet the current energy requirements and conform to conservation area regulations. It also gives a window with a far superior appearance than uPVC alternatives.

Sliding windows with sash were initially only found in large buildings or public buildings, though this changed as production became less expensive and craftsmen could create larger frames using more glass. By the late 18th century Sash windows were the most popular design of wood in the majority of British homes. Since they were easy to open, sash windows let light into rooms without curtains.

The early windows were made of plain glass However, by the 17th Century, sash windows began to become more ornamental. They started with coloured glazing bars, also known as mullions. These windows were quite expensive at the time, but as glass production improved and cheaper they were a common feature in many period houses.

In the 19th century, it was possible to make large, sturdy glass that didn't require supporting bars. This allowed for the frame to be made bigger, which in turn gave an improved view. This was a significant advancement.

Another significant improvement was the introduction of the double-hung sliding windows at the end of the I920s and beginning of the I930s. The double-hung sliding sash was a significant improvement that came about at the end of the I920s, and at the beginning of the I930s.

Oak was used for older and more luxurious buildings. It is important to maintain the parting bead that separates the sashes. This will stop rattles and draughts. It is also important that the idler and sash pulley wheels are kept in good working order as they help to operate the window.

2. Energy efficiency

As larger and clearer sheets of glass became available, sash windows began replacing hinged casements. Glass plates were set in frames made of timber, which were pinned with glazing sprigs and putty was applied to both sides of the frame to ensure watertightness. This form of glazing gradually superseded leaded lights.

The introduction of sashes created a need for a much 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 range of fasteners used to keep the sashes in the right place. These were often decorated with motifs, inscriptions and engraved patterns that identified the maker.

With regular maintenance, sash windows are very energy efficient. But, if you don't maintain them, they may become drafty and let in cold air. Draughts can also be caused by the deterioration of putty and paint. This can be remedied by using wood-to-timber repair products that are specifically designed for this purpose.

The industry of replacement windows is based on the perception that old windows are damaged and beyond economical repair, while they can be easily maintained with just a little care. However, repairs to these windows can be expensive and involve significant disruption to your home. To avoid this homeowners, many opt for a complete replacement with PVC-u windows from one the many "one-stop shop" installation companies. They can take down and replace all windows in a house in just one day, eliminating the need to coordinate different tradesmen and making the whole process much more efficient. They can also be supplied with energy-saving double-glazing, which can achieve more energy efficient ratings than those offered by traditional windows with sash. However double-glazed windows cannot reproduce the proportions and section of traditional timber sashes.

3. Security

Traditional windows can be made secure without compromising their aesthetics. Ironmongery, such as mortice bolts, sash chain and sash lock could be used. They can be fitted to ensure that the window remains capable of being opened for ventilation or for cleaning. They are generally minimal in appearance, as they are designed to complement the sash window. They can be used with traditional sash window mechnism repair (visit the up coming internet page) catch. They should be replaced by more robust models like ones that have double screws or spring levers, to minimize the risk of being hammered.

Sash-window frames are traditionally made of oak or slow-grown deal. Where glazing bars have survived they should be kept and if it is feasible, the wood of the cill should be replaced by identical wood. PVC-u companies often offer a one stop shop installation service, removing and replacing windows on a complete home in a single day without the need to involve other tradespeople, or coordinate visits from different suppliers.

4. Ventilation

Sash windows were first introduced in the 17th century and allowed for a huge amount of light into buildings. By the end of the 18th century, they were adapted to allow even more light into rooms and bigger glazing panes started to be produced. The result was a lighter look and windows with more elegance.

Sash windows were introduced that required a brand new range ironmongery. Early pulleys were made from wood, whereas later Victorian ones were made of brass or a mixture of lead and wood and there were a variety of shutter hinges and knobs. Ironmongery elements must be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

To ensure they remain in good shape, timber windows require regular maintenance. A lack of regular attention can lead to:

Sashes that do not slide easily.

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

The putty can be soaked by water and cause decay to the frame or cill.

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

The window replacement industry has done a great job convincing homeowners that their old windows were decayed and drafty. They were also beyond the budget for repair. The reality is that many old windows made of wood are in good shape and with minor repairs can easily be repaired for many years to come.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. Inability to maintain it properly could result in sash cords breaking, excessive wear on the glazing bars and deterioration of paint and putty. The removal of sashes can also cause structural movement in the frame, causing the sash not to close properly. The sash can also be stuck in the open position, which allows the water and drafts to enter the property.

Damage to windows made of timber is often caused by moisture penetration. This can be prevented with careful painting, regular repairs to upvc doors, and removing the source of dampness. Wet rot is easily identified due to the wavy appearance of the paint, which can be removed to reveal rotting, soft timber. The rotten timber sections should be carefully removed and the affected area should be scarfed together or glued together by using replacements of the same kind as the timber that remains. This method of repair maximizes the amount of fabric used in the first place and is among the least invasive ways to treat the rot that occurs between timber and timber.

The use of a resin-based wood consolidant is a different option to traditional sanding and staining. It is brushed on the surface of the timber to stabilise and protect it from further damage. It is particularly beneficial for the treatment of sash cords and pulleys where it can help to stop breakage.

It is crucial that any old ironmongery like sash stays and latches be kept and rehabilitated instead of being replacing them. They can be extremely difficult to replace without damaging the quality of the original design. It is also recommended that the use of modern aluminum fittings like chain stays and sash lifts is avoided whenever possible as they can cause corrosion and deterioration to frames and sashes made from timber.
