These windows were quite expensive at the time, but as glass production became more efficient and less expensive, they became a part of many of the period homes.

In the 19th century it was possible to manufacture large, sturdy glass that did not need supporting bars. This allowed the frame size to be enlarged further and this in turn gave a better view out of the window. This was an important innovation.

Another significant improvement was the introduction of the double-hung sliding windows at the end of I920s and at the beginning of I930s. This allowed both the upper and lower sash to be opened simultaneously and also improved the ventilation of a building.

The result was a much lighter appearance, and windows with a greater degree of elegance than before.

The introduction of sash windows also required an entirely new range of ironmongery. Early pulleys were of wood, later Victorian ones were made from brass or a combination of lead and wood, and there were many kinds of shutter hinges and knobs. The ironmongery pieces need to be kept clean and preserved in order to appreciate their exquisite design.

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

sashes that no longer slide smoothly.

Holes in the frame which allow water to get in and cause damage and decay.
