The first windows were made of clear glass, but in the 17th century the sash windows began to become more attractive. They started with coloured glazing bars, also known as mullions. They were costly initially, but as glass production became less expensive and more efficient, they were an integral feature in many period houses.

In the 19th century, it became possible to produce large, sturdy glasses that did not require support bars. This allowed the frame size to increase further and this in turn meant more of a view out of the window. This was an important innovation.

2. Energy efficiency

Sash windows replaced hinged casements as clearer and larger sheets were made available.

This type of glazing gradually replaced the leaded light bulbs.

Sashes were introduced, which led to an increase in demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights and stoppers for sashes, shutter hinges and handles as well as various fasteners used to secure the sashes. These were usually decorated with patterns, inscriptions and engravings to identify the maker.

With regular maintenance, sash windows can be extremely energy efficient. Without this maintenance they can get noisy. Paint and putty may cause draughts too. You can fix this problem with wood-to-timber products.

The industry of replacement windows relies heavily on the belief that old windows are damaged beyond repair and are not able to be maintained economically. However, they can easily be maintained with a little attention. Repairs can be costly and cause many disruptions in the home. Many homeowners decide to replace their windows using PVC-u from a large "one-stop shop" company for installation. These can remove and replace all the windows in an entire house in just one day, avoiding the need to coordinate different tradesmen and making the entire process much quicker.

The result was a lighter look and windows that were more elegant.
