1. Aesthetics

Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes that are modular, are able to be restored to original dimensions. This lets the restoration meet modern day energy requirements while complying with conservation area regulations. It also offers windows that have a superior appearance than the uPVC alternatives.

Sliding frames for windows made of sash were originally only used for large buildings or public buildings. However, this changed when production became cheaper and artisans could produce larger frames with greater glass. By the late 18th century windows made of sash were the predominant design of wood in the majority of British homes. Since they were easy to open, sash windows let light into rooms without the need for curtains.

Early windows were plain glass, but in the 17th century sash windows began to become more decorative, with coloured glazing bars and moulded mullions. They were expensive at first, but as glass production became less expensive and more efficient, they became an integral feature in many period houses.

In the 19th century, it became possible to make large, sturdy glasses that did not require support bars. This allowed the frame to be made bigger and, in turn, gave an improved view. This was an important innovation.

Another important improvement was the introduction of the double-hung sliding window at the end of I920s and the beginning of the I930s. This allowed both the upper and lower sash to be opened at the same time and gave improved ventilation to buildings.

Sash windows replaced hinged cases as clearer and larger sheets became available. Plate glass was set into frames of timber that were rebated, then pinned with glazing sprigs and putty was sprayed on both sides of the frame to ensure watertightness. This form of glazing gradually superseded led lights.

The introduction of sashes resulted in an need for a greater variety of ironmongery, including the most basic fittings, 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 place. They were often decorated with motifs, inscriptions, and engraved patterns to identify the maker.

The industry of replacement windows is based on the perception that old windows are damaged and beyond repair, whereas they are able to be maintained with just a little care. Repairs can be costly and cause lots of disruption to the home. Many homeowners opt to replace their windows using PVC-u from a 'one-stop shop' installation company. They can replace all windows in a home in a single day, saving time and avoiding the need for different tradesmen to coordinate. They are also available with 'energy saving' double-glazing to achieve higher energy efficiency ratings than those offered by traditional windows made of sash. These double-glazed windows aren't capable of resembling the proportions and sections of historic timber sashes.

3. Security

Traditional windows can be secured without compromising their style. A variety of ironmongery types can be installed, including sash chains, mortice bolts and sash locks.

If glazing bars have survived, they should be kept and if it is possible, the timber of the cill should be replaced by the same wood. PVC-U companies usually provide a one-stop shop installation service, removing and replacing windows on an entire house in a day without the need to involve other tradespeople or coordinate visits from a number of different suppliers.

4. Ventilation

Sash windows were first introduced in the 17th century and allowed for a huge amount of light into buildings. In the 18th century, they were modified to allow more light could be let into the rooms. Larger glass panes were also made. The result was a more light appearance and windows that were more elegant.

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

Timber windows require regular maintenance to ensure they remain in good condition. Lack of attention to them regularly could lead to:

Sashes that no longer slide easily.

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

break down of putty allowing water to penetrate, which can lead to decay in the frame and cill.

Steel casement windows were popular in the I920s and I930s because they were strong and slim, cost-effective and matched the trend of healthy living. Studies have shown that softwood sash window are just as efficient as PVC-u windows and can even be more attractive.

Wet rot is recognisable due to the wavy appearance of the existing paint which can be stripped to reveal rotting, soft timber. Any rotten timber sections must be removed and the affected part carefully cut or pieced with replacements made from the same type of wood as those remaining. This method of repair maximizes the amount of fabric that was originally used and is one of most minimally invasive methods of treating the rot that occurs between timber and timber.
