How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge feature traditional sash window and the homeowners are proud of their appearance. However, sash windows can become stuck and difficult to open or close. This is usually due moisture that can cause the wood to expand.

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

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes and are modular, are able to be restored to their original size. This allows the restoration to meet the current energy standards while complying with conservation regulations for the area. It also gives windows with a more attractive appearance than uPVC alternatives.

Sliding sash windows were originally only used in large structures or public buildings, however this changed when production became cheaper and craftsmen could create larger frames using more glass. In the 18th century, Sash windows were the most popular wooden design in most British properties. As they were easy to open, sash windows let light into rooms without the need for curtains.

The first windows were made of glass that was plain however, by the 17th Century, sash windows began to become more attractive. They started with coloured glazing bars or mullions. These windows were quite expensive at the time, but as glass production became more efficient and less expensive, they were a common feature in numerous period houses.

In  window replacement cambridge , it became possible to make large, sturdy glasses that didn't need supporting bars. This allowed the frame's size to increase further, which meant more of a view from the window. This was a very important innovation.

The introduction of the double-hung sliding sash was another significant improvement that came about at the end of the I920s and at the 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 in older examples and for more prestigious buildings. A split bead divides the two sashes and it is essential that it is well maintained to prevent rattles and drafts. It is also essential that sash pulleys and idler wheels are in good condition as these assist in operating the window.

2. Energy efficiency

Sash windows were replaced by hinged casements as larger and clearer sheets became available. They were made of plate glass, placed within timber frames with rebates and then pinned with glazing sprigs and putty on both sides to make them watertight. This form of glass gradually replaced led lights.

The introduction of sashes led to the need for a greater variety of ironmongery, with the basic fittings being brass pulleys, lead (and later cast iron) weights, sash stops shutter hinges and knobs, and a range of fasteners to hold the sashes to their the right place. These were often decorated with motifs, inscriptions and engraved patterns that identified the maker.

Sash windows can be very energy efficient when they are maintained regularly. Without this maintenance they could become draughty. Paint and putty can cause draughts. It is possible to fix this issue by using wood-to-timber solutions.

The market for replacement windows rests on the perception that older windows are old and beyond repair, while they can be easily maintained with just a little care. However, these repairs are costly and can cause considerable disruption to the home. Many homeowners opt to replace their windows with PVC-u from a "one-stop shop" installation company. They can replace all windows in a house in one day, saving time and avoiding the need for multiple tradesmen to coordinate. These windows can be equipped with energy-saving double glazing to get higher energy ratings than the traditional windows made of sash. These double-glazed windows aren't capable of replicating the proportions or section of sashes from old timber.

3. Security


It is possible to secure windows that are traditional without compromising on their aesthetics. A variety of ironmongery types are available including sash chains mortice bolts and sash locks. They can be fitted in a way so that the window can be open for ventilation and cleaning. These windows are typically unobtrusive as they are designed to complement sash windows. They can be used with traditional sash window catch. These should be replaced with more robust models, such as those that incorporate double screws or sprung levers in order to reduce the possibility of being hit with hammers.

Sash-window frames were typically made from slow-growing deal or, in the more elegant homes made of oak. Where glazing bars have survived they should be preserved, and where possible, the timber of the cill should be replaced by identical wood. Many PVC-u firms offer a one-stop shop installation service. They can take down and replace windows on a complete home in one day, without the need to involve other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a significant amount of light to be absorbed into buildings. At the end of the 18th century they were modified to let more light into rooms, and larger glazing panes began to be produced. The result was a much more streamlined appearance, and windows that had a higher degree of elegance than before.

Sash windows were introduced, which required a new type of ironmongery. The first pulleys were made of wood, later Victorian ones could be made from brass or a combination of lead and wood, and there were various types of shutter hinges and knobs. Ironmongery elements must be retained and cleaned down so that the quality of their design can be appreciated.

Timber windows require regular maintenance to keep them in good shape. Inattention to maintenance routinely could cause:

Sashes that don't slide smoothly.

Holes in the frame which allow water to get in and cause decay and damage.

break down of putty allowing 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 cheap and were in line with the trend for healthy living. Studies have shown that softwood sash windows are as efficient as PVC-u windows and can even be more attractive.

The replacement window industry was able to convince homeowners that their old windows were rotten drafty, noisy and beyond repair. Many older timber windows can be repaired and used for a long time with minor repairs.

The removal of sashes may also result in structural movement within the frame, causing the sash to not close correctly. It is also possible for the sash be snagged or slammed into an open position, which can let water and draughts into the structure.

Moisture penetration is a common cause of damage to timber windows. This can be prevented with thorough painting, periodic repairs and the elimination of the source of dampness. Wet rot can be identified by the wavy look of the paint that can be stripped away to reveal soft, rotting timber. Any timber that is rotting should be cut off and the affected part carefully scarfed or pieced in using replacements made from the same type of timber as the ones remaining. This method of repair maximizes the amount original fabric and is one of most non-invasive methods to treat the rot that occurs between timber and timber.

A resin-based wood condenser is an alternative to traditional sanding or staining. This is brushed on the surface of the wood to protect it and stabilise it. It is particularly beneficial in the treatment of sash cords and pulleys which help stop breakage.

It is important to restore and not replace any historic ironmongery, such as the sash latches and stays. These items are difficult to replace without compromising the the original design. It is recommended that the use of modern aluminium fittings like sash lifts and chain stays is avoided whenever feasible as they could cause corrosion and deterioration to frames and sashes made of timber.
