How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and homeowners are proud of how they appear. Sash windows can get stuck and be difficult to open or shut. This is usually due to moisture that can cause the wood to expand.

Traditionally, window boxes utilised chains or cotton cords and lead weights to operate. Modern sash windows come with hidden springs to address this problem.


1. Aesthetics

Unlike PVC-u windows that are constructed to modular imperial sizes Timber sash windows can be restored to their original dimensions. This allows the restoration of timber sash windows in order to comply with current energy standards and conform to conservation area regulations. It also comes with an option that is superior to the uPVC alternatives.

Sliding windows with sash were initially only used in large buildings or public buildings, however the production process was less expensive and craftsmen were able to make larger frames with more glass. At the end of the 18th century, sash windows had become the most sought-after wooden style in British homes. Sash windows were easy to operate and let light in rooms without the need for curtains.

The early windows were made of clear glass however, in the 17th century the sash windows began to become more ornamental. They began with colored glazing bars or mullions. They were expensive at the time but as glass production improved and less expensive, they were a common feature in numerous period houses.

In the 19th century, it was possible to produce large, sturdy glasses that did not require supporting bars. This allowed the frame to be made larger, which in turn gave a better view. This was an important advancement.

windows and doors cambridge was the introduction of the double-hung sliding window at the end of I920s and the beginning of the I930s. The double-hung sliding sash is another important improvement that came into existence at the end of the I920s, and at the beginning of the I930s.

Oak was used in older examples and more prestigious buildings. A split bead divides the two sashes, and it is important that this is maintained to prevent rattles and draughts. It is also crucial that the idler and sash pulley wheels are in good shape as they aid in operating the window.

2. Energy efficiency

Sash windows replaced hinged casements as clearer and larger sheets were made available. Plate glass was set into frames made of timber, which were secured with glazing sprigs and putty was then sprayed onto both sides of the frame to ensure watertightness. This kind of glazing gradually replaced leaded lights.

The introduction of sashes resulted in the need for a larger variety of ironmongery including the most basic fittings, brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges, knobs and shutters as well as a range of fasteners that secured the sashes into place. These were often decorated with motifs, inscriptions, and designs that were engraved to identify the maker.

With regular maintenance, sash windows can be very energy efficient. If they are not maintained they could become noisy. Paint and putty may cause draughts too. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The market for replacement windows is based heavily on the belief that old windows are beyond repair and therefore cannot be maintained economically. However windows can be easily maintained with a bit of 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 made by one of the many "one-stop shop" installation companies. They can replace all windows in a house in one day, thereby saving time and eliminating the need for multiple tradesmen to coordinate. They can also be supplied with energy-saving double-glazing, which can achieve greater energy efficiency than traditional sash windows. However these double-glazed units are unable to replicate the section and proportions of the sashes made of timber from the past.

3. Security

It is possible to secure traditional windows without compromising their appearance. Ironmongery, such as mortice bolts, sash chain, and sash lock can be used. These can be put in place to ensure that the window is capable of being opened for ventilation or cleaning. They are generally not noticeable, since they are designed to match the sash window. They can be utilized in conjunction with traditional sash-window catchers and should be replaced with more robust versions (such ones that have double screws) or spring-loaded levers to minimize the possibility of them being hammered out.

Sash-window frames are traditionally made of oak or slow-grown deal. If glazing bars have survived, they should be kept, and, if it is possible, the timber of the cill should be replaced by matching wood. PVC-u companies often provide a one-stop shop installation service, removing and replacing windows on an entire house in a day without the need to engage other tradespeople, or coordinate visits from 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 18th century, they were modified so that more light could be let into rooms. Larger glass panes were also made. The result was a more light appearance and windows with more elegance.

The introduction of sash windows also necessitated the creation of a new line of ironmongery. Early pulleys could be made out of wood. Later Victorian ones were made of brass or a combination of wood and leaded. There were also different types of shutter hinges and knobs. The ironmongery components should be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

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

sashes that no longer slide smoothly.

holes in the frame allow water causing damage and decay.

Water can get into the putty and cause decay to the frame or cause cill.

In the I920s and I930s steel casement windows grew in popularity due to their durability slim and affordable, and complemented the vogue for healthy living. However, research has revealed that traditional softwood sash windows are as efficient in thermal efficiency as double-glazed PVC-u windows and are more attractive than the sleek lines of modern casement windows.

The industry of replacement windows was able to convince homeowners that their old windows were decayed, drafty and beyond economical repair. Many old windows made of timber can be fixed and utilized for a longer period with minor repairs.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. If you don't maintain your window's sash, it could cause the sash cords breaking, and the glazing bars wearing out excessively. It can also cause paint and putty degrade. The removal of sashes can also result in structural movements within the frame, causing the sash to not close correctly. The sash can also be stuck in its open position, allowing the water and drafts to enter the building.

Moisture penetration is the most common cause of damage to windows made of timber. This can be avoided by regular repairs as well as thorough painting, and then removing the source of dampness. The paint can be removed to expose the soft, rotting wood. The sections of timber that are rotten should be carefully removed, and the affected area should be scarfed together or pieced together using replacements of the same type as the remaining timber. This method of repair increases the amount of fabric used in the first place and is among the most non-invasive methods to treat the rot that occurs between timber and timber.

A resin-based wood condenser is an alternative to traditional staining or sanding. This is brushed onto the surface of the wood to help stabilize it and protect it from further damage. It is especially useful for treating sash and pulley cords, which can help prevent breakage.

It is important to restore and not replace any old ironmongery, such as the sash latches and stays. It is difficult to replace these items without compromising their original design. It is recommended that the use of modern aluminium fittings such as chain stays and sash lifts is avoided if at all feasible as they could cause corrosion and damage to frames and sashes made from timber.
