Sliding windows with sash were initially only used in large buildings or public buildings. However, this changed when production became cheaper and artisans could make larger frames using greater glass. By the end of the 18th century, sash windows had become the most popular wooden style in British homes. Since they were easy to open, sash windows let light into rooms without curtains.

Sash windows replaced hinged cases as larger and clearer sheets were made available. They were glazed with plate glass placed within timber frames with rebates and pinned in place using glazing sprigs and putty on both sides to make them watertight. This kind of glazing gradually replaced the leaded light bulbs.

The introduction of sashes resulted in the need for a greater variety of ironmongery, including the most basic fittings, brass pulleys as well as lead (and later cast iron) weights, sash stops shutter hinges and knobs, and a range of fasteners used to keep the sashes into place. These were often decorated with motifs, inscriptions, and designs that were engraved to identify the maker.

4. Ventilation

When sash windows were first introduced in the 17th century they allowed a significant amount of light into structures. At the end of the 18th century, they were altered to allow even more light into rooms, and larger glass panes began to be produced. The result was a lighter appearance and windows with more elegance.

Sash windows were introduced, which required a new range ironmongery. The first pulleys were made of wood, whereas later Victorian ones could be made from brass or a mixture of wood and lead, and there were various types of shutter hinges and knobs.

Damage to timber windows is often caused by moisture entry. This can be avoided by thorough painting, regular repairs and elimination of 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 part carefully wrapped or pieced back using replacements made from the same type of wood as the ones that remain. This repair method increases the amount of fabric used in the first place and is among the least invasive ways to treat wood-to-timber rot.

A resin-based wood condenser is an alternative to traditional staining or sanding. This is brushed on the surface of the wood to protect it and strengthen it. It is particularly beneficial for the treatment of sash cords and pulleys where it can help to stop breakage.
