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 can become stuck and 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 or cotton cords as well as lead weights. Modern windows with sash springs are concealed to avoid this issue.

1. Aesthetics

Timber sash windows, unlike PVC-u windows which are manufactured in imperial sizes, which are modular, can be reconstructed to original dimensions. This permits the re-installation of timber sash windows in order to comply with current energy standards and to comply with conservation area regulations. It also provides an option that is superior to uPVC options.

Sliding windows with sash were initially only used in large structures or public buildings, however this changed when production became cheaper and craftsmen could create larger frames using more glass. At the close of the 18th century, sash windows had become the most sought-after wooden style in British homes. As they were easy to open, sash windows let light into rooms without the need for curtains.

The first windows were made of plain glass however, in the 17th century, sash windows began to be more decorative. They began with colored glazing bars or mullions. They were costly at the beginning but as glass production became cheaper and more efficient, they became a common feature in many homes of the period.

In the 19th century, it became possible to produce large, sturdy glasses that did not require supporting bars. This allowed the frame's size to increase further, which meant more of a view out of the window. This was a significant advancement.

The introduction of the double-hung sliding sash was another important improvement that occurred 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. A parting bead separates the two sashes and it is essential that it is maintained to prevent rattles and draughts. The idler wheels, sash pulleys and sash rollers are essential for the proper operation of the window.

2. Energy efficiency

As larger and clearer sheets of glass became available, sash window began to replace hinged casements. Plate glass was set into rebated timber frames, pinned with glazing sprigs and putty was applied to the frame's sides to ensure watertightness. This kind of glazing gradually replaced the leaded light bulbs.

The introduction of sashes created the need for a wider range of ironmongery, with the basic fittings being brass pulleys, lead (and later cast iron) weights, sash stops, shutter hinges and knobs as well as a range of fasteners used to keep the sashes in the right place. They were often decorated with motifs, inscriptions, and patterns engraved to identify the maker.

With regular maintenance, sash windows are very energy efficient. Without this maintenance they could become noisy. Draughts can also be caused by the deterioration of putty and paint. It is possible to fix this issue with wood-to-timber products.

The industry of replacement windows relies heavily on the perception that old windows are damaged beyond repair and are not able to be maintained economically. However windows can be easily maintained with a little attention. However, these repairs can be costly and cause considerable disruption to the home. To prevent this homeowners, many choose to replace their windows with PVC-u windows from one the large 'one stop shop' installation companies. They can replace and remove all windows in a house in a single day, avoiding the need to coordinate different tradesmen and making the whole process much faster. They can also be fitted with 'energy-saving' double glazing cambridge-glazing to get higher energy efficiency ratings than traditional windows made of sash. However double-glazed windows cannot duplicate the proportions and section of traditional timber sashes.

3. Security

It is possible to secure traditional windows without compromising their style. There are many types of ironmongery that are available including sash chains mortice bolts, and sash locks. These can be put in place in a way that the window is still open to allow ventilation or cleaning. These products are usually minimal in appearance, as they are designed to fit the sash window. They can be used alongside traditional sash-window catches, which must be replaced by more robust models (such ones that have double screws) or spring levers to decrease the risk of them being hammered out.

Sash-window frames were made from slow-growing deal or, in more elegant homes, from oak. If the glazing bars remain intact and in good condition, they should be kept. If feasible, the cills made of timber should be replaced with wood that matches. PVC-u companies typically 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 large amount of light to be absorbed into buildings. At the end of the 18th century, they were modified to let even more light into rooms and bigger glazing panes started to be made. The result was a lighter look and windows that were more elegant.

Sash windows were introduced and required a new type of ironmongery. Early pulleys could be made from wood. Later Victorian ones were made of brass or a mixture of wood and leaded. There were also different kinds of knobs and shutter hinges. These ironmongery pieces should be maintained and cleaned to appreciate their fine design.

Timber windows require regular maintenance to ensure they remain in good condition. Inattention to maintenance routinely could cause:

Sashes that no longer slide smoothly.

Holes in the frame which allow water to get in 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 revealed that traditional softwood sash windows are just as thermally efficient as double-glazed PVC-u windows and are more attractive than the sleek lines of contemporary casement windows.

The window replacement industry has done a lot to persuade house owners that their windows are dirty, noisy and beyond repair. The reality is that many older windows made of wood are in good condition and, with minor repairs, could easily be maintained for years to come.

5. Maintenance

Traditional sash windows require regular maintenance and inspection. If you don't maintain your sash window, it can cause the sash cords breaking, and the glazing bars wearing out excessively. It can also cause paint and putty to deteriorate. The removal of sashes may also cause structural shifts within the frame, which causes the sash to move out of alignment and unable to close correctly. It is also possible for the sash to be stuck or fixed in an open position, which can let water and draughts into the structure.

Moisture penetration is a common cause of damage to windows made of timber. This can be avoided by careful painting, regular repairs to Upvc doors and the elimination of the source of dampness. The paint can be removed to reveal the soft, rotting wood. The sections of timber that are rotten should be carefully cut out and the affected part should be scarfed together or pieced together by using replacements of the same kind as the timber that remains. This method of repair increases the amount of fabric left, and is among the least invasive methods of treating decay caused by timber.

The use of a resin-based wood consolidant is a different option to the traditional method of staining and sanding. The product is brushed on to the surface of the wood to help stabilize it and shield it from further damage. It is especially beneficial for the treatment of pulley cords and sash which can help prevent breakage.

It is important to restore and not replace any old ironmongery such as sash latches and stays. It is difficult to replace these items without altering their original design. It is also recommended that modern aluminium fittings, such as sashlifts and chainstays, be avoided as they could cause corrosion and deterioration of timber frames and sashes.Window-Repairs.-150x150.jpg
