1. Aesthetics

Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes and are modular, can be reconstructed to their original dimensions. This allows for the restoration of timber sash windows to meet the current energy requirements and to comply with conservation regulations for areas. It also offers a window with a far more attractive appearance than uPVC alternatives.

Sliding windows with sash were initially only used in large buildings or public buildings, though this changed as production became less expensive and craftsmen could produce larger frames with more glass. By the end of the 18th century, sash windows were the most sought-after wooden style in British homes. Sash windows were easy to operate and let light into rooms without the use of curtains.

Early windows were simple glass, but in the 17th century, sash windows were becoming more decorative, with coloured glazing bars and moulded mullions. They were costly at first, but as glass production became less expensive and more efficient, they were a common feature in many historic homes.

In the 19th century, it was possible to manufacture large, sturdy glass that did not need support bars. This allowed the frame to be made larger, which in turn gave a better view. This was a significant innovation.

The introduction of the double-hung sliding sash was another important improvement that was made at the end of the 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.

Glass plates were set in rebated timber frames, secured with glazing sprigs and putty was applied to the frame's sides to ensure watertightness. This type of glazing gradually replaced leaded lights.

The introduction of sashes created the need for a greater variety of ironmongery, with the basic fittings being brass pulleys and 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. These were often decorated in patterns, inscriptions and engraved patterns to identify the maker.

These can remove and replace all windows in a home in just one day, eliminating the need to co-ordinate different tradesmen, making the whole process much more efficient. These windows can be fitted with 'energy-saving' double glazing to achieve higher energy ratings than the traditional windows made of sash. However these double-glazed units are unable to replicate the section and proportions of historic timber sashes.

3. Security

Traditional windows can be made more secure without compromising their appearance. There are many types of ironmongery that are available including sash chains mortice bolts and locks for sash. These can be installed in a way so that the window is able to be opened for ventilation and cleaning. These are typically not noticeable, since they are designed to complement the sash window.

Sash-window frames are typically made from oak or slow-grown deal. If the glazing bars are still intact and are not damaged, they should be left. If feasible, the cills made of timber should be replaced by wood that matches. PVC-u companies often offer a one stop shop installation service, removing and replacing windows across a home in a single 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 huge amount of light to be absorbed into buildings. By the end of the 18th century, they were modified to let more light into rooms, and larger glass panes began to be manufactured. The result was a lighter appearance and windows with a higher degree of elegance than before.

Sash windows were introduced, which required a new type of ironmongery. Early pulleys were made from wood, while later Victorian ones could be made from brass or a mixture of lead and wood, and there were many kinds of shutter hinges and knobs. Ironmongery elements must be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

To keep them in good shape, timber windows must be maintained. Lack of regular attention may lead to:

Sashes that do not move effortlessly.

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

The removal of sashes can also result in structural shifts within the frame, which causes the sash to move out of alignment and in a position that it is not able to close properly. The sash can also be stuck in an open position, which allows water and draughts to enter the building.

Damage to windows made of timber is usually caused by moisture penetration. This can be avoided by regular repairs by thorough painting and eliminating the source of dampness. The paint can be removed to reveal the soft, decaying wood. Any timber that is rotting should be cut out and the affected area carefully cut or pieced with replacements made from the same type of timber as the ones that remain. This repair method increases the amount original fabric and is among the most non-invasive methods to treat the rot that occurs between timber and timber.

The use of a resin-based wood consolidant is an alternative to traditional sanding and staining. This is brushed onto the surface of the wood to help stabilize it and protect it from further damage.
