1. Aesthetics
Timber sash windows, in contrast to PVC-u windows that are made in imperial sizes that are modular, can be reconstructed to their original size. This allows the restoration to meet modern day energy requirements while ensuring compliance with conservation regulations for the area. It also provides windows that have a more attractive appearance than uPVC alternatives.
Sliding windows with sash were initially intended for large structures or public buildings. However, this changed when production became more affordable and artisans could make larger frames using larger glass. By the end of the 18th century, sash windows had become the most popular wooden design in British homes. Since they were easy to open, sash windows let light into rooms without the need for curtains.
The early windows were made of glass that was plain, but in the 17th century, sash windows began to become more ornamental. They began with colored glazing bars or mullions. They were costly at first, but when glass production became less expensive and more efficient, they were commonplace in many historic homes.

If it is it is possible, the cills of the timber should be replaced with timber that is compatible with. PVC-U companies usually offer a one stop shop installation service, removing and replacing windows on an entire home in one day, without the need to engage other tradespeople or co-ordinate various visits from different suppliers.
4. Ventilation
Sash windows were introduced in the 17th century and allowed for a significant amount of light into buildings.

Sash windows were introduced, which required a new range ironmongery. Early pulleys were made out of wood. Later Victorian ones were made of brass or a mix of leaded and wood. There were also different kinds of knobs and shutter hinges. The ironmongery pieces need to be maintained and cleaned to appreciate their beautiful design.
To ensure they remain in good condition, timber windows require regular maintenance. A lack of regular attention can result in:
Sashes that don't slide smoothly.
Holes in the frame which allow water to get in and cause damage and decay.
break down of putty allowing water penetration that can lead to decay in the frame and cill.

The paint can be removed to expose the soft, rotting wood. The sections that are rotting must be removed with care and the affected area should be scarfed or glued together using replacements of the same nature as the rest of the timber.
