Sliding frames for windows made of sash were originally intended for large structures or public buildings. However, this changed when production became cheaper and artisans could create larger frames using more glass. By the late 18th century Sash windows were the most popular design of wood in the majority of British homes. Since they were easy to open sash windows allowed light into rooms without curtains.
The early windows were made of clear glass, but in the 17th century, sash windows began to be more decorative. They began with colored glazing bars or mullions. These were very expensive at the time but as glass production improved and cheaper they became a part of many of the period homes.
In the 19th century, it became possible to produce large, strong glasses that did not require support bars. This allowed the frame to be enlarged, which in turn gave the viewer a better view. This was a significant innovation.
Another significant improvement was the introduction of the double-hung sliding window at the end of I920s and the beginning of the I930s. The double-hung sliding sash was a important improvement that was made at the end of the I920s, and at the beginning of the I930s.

2. Energy efficiency
Sash windows were replaced by hinged casements as larger and clearer sheets were made available. Glass plates were set in frames of timber that were rebated, then secured with glazing sprigs and putty was then sprayed onto the frame’s two sides for watertightness. This type of glass gradually replaced the use of leaded lights.
Sashes were introduced, which resulted in increased demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights and stoppers for sashes shutter hinges and handles, and various fasteners used to fix the sashes. These were often decorated in motifs, inscriptions, and engravings to identify the maker.

3. Security
It is possible to secure windows that are traditional without compromising on their aesthetics. Many types of ironmongery can be fitted with sash chains, mortice bolts and locks for sash. These can be installed to ensure that the window is capable of being opened for ventilation or for cleaning. These products are often unobtrusive as they are designed to complement sash windows. They can be used alongside traditional sash-window catches that are required to be replaced with more robust versions (such ones with double screws) or spring levers to decrease the risk of them being hammered out.

Where possible, the timber cills should be replaced with wood that is in line with. PVC-u companies typically provide a one-stop shop installation service that can remove and replacing windows across a house in a day without the need to engage other tradespeople or coordinate visits from a number of different suppliers.
4. Ventilation
When sash windows were first introduced in the 17th century they allowed a substantial amount of light to flood into buildings. In the 18th century, they had been adapted so that even more light could be let into the rooms. Larger glazing panes were also produced. The result was a much lighter appearance and windows with a greater quality of design than before.
Sash windows were introduced and required a new type of ironmongery. Early pulleys were made of wood. Later Victorian ones were made of brass or a mixture of leaded and wood. There were also different kinds of knobs and shutter hinges. These ironmongery elements should always be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.
Timber windows require careful maintenance to ensure they remain in good order. Lack of regular attention may result in:
Sashes that do not slide easily.
Holes in the frame which allow water to enter and cause decay and damage.
break down of the putty and allow water penetration, which can lead to decay in the frame and cill.

The removal of sashes could also cause structural movement in the frame, which can cause the sash to not close properly. The sash may also become stuck in its open position, allowing the water and drafts to enter the property.
Moisture penetration is a common cause of damage to windows made of timber. This can be prevented with thorough painting, periodic repairs to upvc doors and the elimination of the cause of dampness. The paint can be removed to expose the soft, decaying wood. The sections that are rotting should be carefully cut out and the affected part should be scarfed or pieced together with replacements of the exact kind as the timber that remains.
