How to Restore timber double glazed windows cambridge Sash Windows in Cambridge

Many homes in Cambridge have sash windows with traditional designs and homeowners are proud of the way they appear. Sash windows can become stuck and are difficult to open or close. This is typically due to moisture which can cause the wood to expand.

Traditionally, window boxes used chains or cotton cord and weights made of lead to operate. Modern sash windows feature hidden springs to address this problem.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes that are modular, are able to be restored to their original dimensions. This allows the restoration of timber sash windows in order to meet the current energy requirements and comply with conservation area regulations. It also provides upvc windows cambridge that have a superior appearance than upvc windows cambridge alternatives.

Sliding sash window frames were initially only used for large buildings or public buildings. However the production became more affordable and artisans could make larger frames using greater glass. By the late 18th century Sash windows were the most popular wooden style in a 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 by the 17th Century sash windows started to become more ornamental. They started with coloured glazing bars or mullions. They were expensive at first, but as glass production became cheaper and more efficient, they were a common feature in many homes of the period.

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

Another significant improvement was the introduction of the double-hung sliding window at the end of I920s and at the beginning of the I930s. The double-hung sliding sash was a important improvement that was made at the end of the I920s and beginning of the I930s.

Oak was used in older examples and more prestigious buildings. A split bead divides the two sashes. It is essential that it is maintained in order to avoid rattles and draughts. The idler wheels, sash pulleys and sash rollers also are essential to the functioning of the window.

2. Energy efficiency

Sash windows replaced hinged cases as larger and clearer sheets were made available. They were coated with plate glass that was set within rebated timber frames and secured with glazing sprigs and putty on both sides to ensure they were watertight. This form of glazing gradually replaced led lights.

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

Sash windows are energy-efficient with regular maintenance. However, without this maintenance they may become drafty and let in cold air. Draughts can also be caused by the breakdown of paint and putty. This issue can be fixed with wood-to-timber products.

The market for replacement windows is based heavily on the notion that older windows are beyond repair and therefore cannot be maintained economically. However windows can be easily maintained with a little attention. Repairs can be expensive and cause many disruptions in the home. To avoid this, many homeowners prefer to replace their windows with PVC-u windows from one the many "one stop shop" installation companies. They can replace all windows in a home in one day, thereby saving time and eliminating the need for different tradesmen to coordinate. These windows can be fitted with energy-saving double glazing to get higher energy ratings than traditional windows made of sash. These double glazing seal repairs-glazed units are not capable of replicating the proportions and section of the sashes made of timber from the past.

They can be used alongside traditional sash-window catchers, which are required to be replaced with more robust versions (such ones with double screws) or spring levers to decrease the chance of them being hammered open.

Sash-window frames were constructed from slow-growing deal or, in more elegant homes made of oak. If the glazing bars are in good condition and are not damaged, they should be left. Where possible, the timber cills should be replaced with timber that is compatible with. Many PVC-U companies offer a one-stop shop installation service. They can take out and replace windows on a complete home in a single day, without involving other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a significant amount of light into buildings. At the end of the 18th century, they had been modified so that more light could be let into rooms. Larger glass panes were also created. The result was a more streamlined appearance, and windows with a greater level of elegance than they had before.

Sash windows were introduced, which required a new type of ironmongery. Early pulleys were made from wood, whereas later Victorian ones could be 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 maintained and cleaned to appreciate their fine design.

To ensure they remain in good shape, timber windows must be maintained. Inattention to maintenance routinely could result in:

sashes that no longer slide easily.

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

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

In the I920s and the I930s steel casement windows grew in popularity due to their strength slim and affordable, and complemented the vogue for healthy living. Studies have shown that softwood sash windows are just as efficient as PVC-u windows and can even be more attractive.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. If you fail to maintain your sash window, it can cause the sash cords breaking and the glazing bars deteriorating excessively. It can also cause paint and putty to deteriorate. The removal of sashes could also cause structural movement in the frame, which can cause the sash to not close properly. It is also possible for the sash be stuck or slammed into an open position, which can let water and draughts into the structure.

Moisture penetration is the most common cause of damage to windows made of timber. This can be prevented by regular repairs as well as thorough painting, and then removing the source of dampness. The paint can be removed to reveal the soft, rotting wood. 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 nature as the rest of the timber. This method of repair maximizes the amount of fabric left, 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 process of sanding or staining. This is brushed onto the surface of the timber to stabilise and protect it from further damage. It is particularly beneficial in the treatment of pulleys and sash cords which can help prevent breakage.

It is essential to preserve and not replace any historic ironmongery, like sash latches and stays. These items are difficult to replace without compromising the the original design. It is recommended that the use of modern aluminum fittings like chain stays and sash lifts is avoided if at all feasible as they could cause corrosion and deterioration to frames and sashes made from timber.
