Sliding sash window frames were initially only used in large buildings or public buildings. However this changed as production became cheaper and artisans could make larger frames using greater glass.

The first windows were made of clear glass however, by the 17th Century sash windows started to become more attractive. They began with colored glazing bars or mullions. They were expensive at the beginning but as glass production became less expensive and more efficient, they were a common feature in many homes of the period.
In the 19th century it was possible to make large, strong glass that did not need supporting bars. This allowed the frame's size to increase further, which meant more of a view from the window. This was an important innovation.
Another important improvement was the introduction of the double-hung sliding window repair specialists (similar web-site) at the end of the I920s and beginning of the I930s. 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.

A split bead divides the two sashes. It is essential that it is maintained to prevent rattles and drafts. The sash pulleys, idler wheels and sash rollers are also vital to the operation of the window.
2. Energy efficiency
As clearer and larger glass sheets were made available, sash windows began to replace hinged casements. Glass plates were set in rebated timber frames, which were pinned with glazing sprigs, and putty was sprayed on the frame's two sides for watertightness. This kind of glazing gradually replaced leaded lights.
Sashes were introduced, which resulted in increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers, shutter hinges and handles and various fasteners used to fix the sashes.

They can replace all windows in a house in one day, saving time and eliminating the need for different tradesmen to coordinate. They can also be fitted with 'energy-saving' double-glazing to get more energy efficient ratings than are possible with traditional windows with sash. However double-glazed windows cannot reproduce the proportions and section of traditional timber sashes.
3. Security
Traditional windows can be secured without compromising their aesthetics. Many types of ironmongery are available with sash chains, mortice bolts and locks for sash. These can be installed in a way so that the window is able to be open for ventilation and cleaning. These are typically unobtrusive, as they are designed to complement the sash window. They can be used with traditional sash window catch.

If it is possible, the cills of the timber should be replaced by wood that is in line with. PVC-U companies usually provide a one-stop shop installation service, removing and replacing windows on a complete 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 introduced in the 17th Century and allowed for a large 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 created. The result was a lighter appearance, and windows with a higher quality of design than before.
The introduction of sash windows also required an entirely new range of ironmongery. Early pulleys were made of wood. Later Victorian ones were made of brass or a mixture of wood and lead. There were also a variety of types of shutter hinges and knobs. These ironmongery elements should always be retained and cleaned down so that the fine quality of their design can be appreciated.
Timber windows require careful maintenance to keep them in good order. Inattention to maintenance routinely could result in:
Sashes that don't slide easily.
holes in the frame that allow water, which can cause damage and decay.
The putty can be soaked by water and cause decay to the frame or cause cill.
Steel casement windows became popular in the I920s & I930s because they were strong and slim, cost-effective and complemented the trend for healthy living.

It is also possible for the sash to be stuck or fixed in the open position, which can let water and draughts into the structure.
Moisture penetration is the most common cause of damage to timber windows. This can be avoided with regular repairs as well as thorough painting, and then removing the source of dampness. The paint can be removed to expose the soft, decaying wood. The rotten timber sections should be carefully cut out and the affected area should be scarfed together or glued together with replacements of the exact type as the remaining timber.
