What Freud Can Teach Us About Sash Windows Cambridge
How to Restore Timber Sash Windows in Cambridge

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

Traditionally, box sash windows used chains or cotton cords and lead weights to operate. Modern sash window springs are hidden to solve this problem.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows that are made in imperial sizes and are modular, can be reconstructed to their original size. This allows the restoration to be in line with modern energy requirements while ensuring compliance with conservation areas regulations. It also provides windows that have a more attractive appearance than uPVC alternatives.

Sliding frames for windows made of sash were originally only used for large buildings or public buildings. However this changed as production became less expensive and craftsmen could produce larger frames with greater glass. In the 18th century, sash windows were the dominant wooden design in most British homes. Since they were easy to open sash windows allowed light into rooms without curtains.

Early windows were plain glass but by the 17th century sash windows began to become more decorative, with coloured glazing bars and moulded 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 produce large, strong glasses that didn't need support bars. This allowed the frame to be enlarged, which in turn gave the viewer a better view. This was an important advancement.

The introduction of the double-hung sliding sash is another important improvement that was made 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 examples and more prestigious buildings. A parting bead is used to separate the two sashes and it is important that this is maintained to prevent rattles and drafts. It is also essential that sash pulleys and idler wheels are kept in good working order as they help to operate the window.


2. Energy efficiency

Sash windows were replaced by hinged casements as larger and clearer sheets were made available. Glass plates were set in frames made of timber, which were pinned with glazing sprigs and putty was sprayed on the frame's two sides to ensure watertightness. wooden windows cambridge of glass gradually replaced led lights.

Sashes were introduced, which led to a greater demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges, handles and shutter hinges and various fasteners used to fix the sashes. These were often decorated in designs, inscriptions, and engravings to identify the maker.

Sash windows can be very energy-efficient with regular maintenance. However, if they are not maintained, they can become draughty and let in cold air. Draughts can also result from the degeneration of paint and putty. This can be fixed by using proprietary wood-to-timber repair products.

The industry of replacement windows relies heavily on the belief that old windows are beyond repair and are not able to be maintained economically. However, they can easily be maintained with a little attention. Repairs can be expensive and cause lots of disruption to the home. To avoid this homeowners, many choose to replace their windows with PVC-u windows made by one of the large 'one stop shop' installation companies. They can take down and replace all windows in an entire house in just one day, eliminating the need to co-ordinate different tradesmen, making the whole process much faster. These windows can be equipped with energy-saving' double glazing to achieve higher energy ratings than traditional windows made of sash. These double-glazed units are not able to replicate the proportions and section of sashes from old timber.

3. Security

Traditional windows can be made more secure without compromising their aesthetics. Many types of ironmongery can be fitted including sash chains mortice bolts, and locks for sash. They can be fitted in such a way that the window can still be opened to allow ventilation and cleaning. These windows are typically discrete since they are made to work with sash windows. They can be used with traditional sash window catches. These should be replaced with more robust versions like ones that have double screws or spring levers to decrease the possibility of being struck by hammers.

Sash-window frames were constructed from slow grown deal or, in more elegant homes made of oak. When glazing bars have survived they should be kept, and where feasible, the wood of the cill should be replaced by the same wood. PVC-u companies typically offer a one stop shop installation service that can remove 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 into buildings. By the end of the 18th century, they were adapted to allow even more light into rooms, and larger glazing panes began to be produced. The result was a much lighter appearance and windows with a greater level of elegance than they had before.

Sash windows were introduced and required a new range ironmongery. Early pulleys were made from wood, later Victorian ones could be made from brass or a combination of wood and lead, and there were many kinds of shutter hinges and knobs. These ironmongery elements should always be maintained and cleaned so that the fine quality of their design can be appreciated.

To keep them in good condition, wooden windows need to be maintained. Inattention to maintenance routinely could lead to:

Sashes that don't slide easily.

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

break down of the putty and allow water to penetrate, which could lead to decay of the frame and cill.

Steel casement windows gained popularity in the I920s & I930s due to their strength and slim, cheap and matched the trend of healthy living. Research has proven that softwood sash window are as efficient as PVC-u windows, and may even be more attractive.

The replacement window industry did a lot to convince homeowners that their old windows were rotten drafty, noisy and beyond repair. The reality is that many old timber windows are in good condition and with minor repairs can easily be serviceable for many years to be.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. Inability to keep up with this could result in the sash cords breaking, a lot of wear on the glazing bars, and deterioration of paint and putty. The removal of the sashes could also result in structural movement within the frame that causes the sash to be misaligned and not closing properly. It is also possible for the sash to be snagged or fixed in an open position, which can let water and draughts into the property.

The damage to timber windows is usually caused by moisture infiltration. This can be avoided with regular maintenance, thorough painting and removing the cause of dampness. The paint can be removed to expose the soft, decaying wood. The sections of timber that are rotten must be removed with care and the affected part should be scarfed or pieced together using replacements of the same type as the remaining timber. This method of repair maximises the amount of original fabric retained and is among the least invasive ways of treating timber-to-timber decay.

The use of a resin-based wood consolidant is another alternative to traditional sanding and staining. This is brushed onto the surface of the timber to stabilise and shield it from further damage. It is particularly useful for the treatment of pulley cords and sash where it can prevent 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 damaging the the original design. It is also recommended that the use of modern aluminium fittings such as sash lifts and chain stays is avoided if at all possible since they can cause corrosion and deterioration to frames and sashes made from timber.
