Windows

Wood Frame Windows

By the 1800’s wooden casement windows were commonplace in both residential and commercial building.  When we think of these windows today, if they have survived, it conjures images of rotting wood, peeling paint, broken glass, and general decay.

In the 19th century fire codes became commonly adopted to protect buildings and their inhabitants. With fire codes and the Industrial Revolution, wooden windows in commercial buildings began to be replaced with rolled steel windows. Although commercial applications were moving to steel windows, residential homes kept the wooden windows. After WWII, wooden windows would begin to see their demise in the residential world with the introduction of aluminum windows. Towards the end of the 20th century the wooden window would fall victim to the introduction of vinyl windows.

Vinyl and aluminum windows were promised to be more energy efficient, cheaper, and offered minimal maintenance. While some of these claims were true in the short term, in the long term, it is not always the case. Aluminum windows were not as strong and needed a bulkier frame. Vinyl windows would often discolor and begin to degrade over time. Both aluminum and vinyl options would often need to change the buildings original façade to make room for the new window. Often, changing the façade resulted in a loss of historic charm and architectural character.

Metal Frame Windows

In the beginning metal framed windows were constructed by artists and typically adorned churches. Only having access to small panes of glass created the necessity for glazing bars/mutins. During the Industrial Revolution Sir Henry Bessemer developed the process for rolled steel windows in 1856. This led to steel windows being readily available by the 1890’s and gained favor in commercial the world. Commercial buildings benefitted to the security, size, and flexibility in design. In 1953 hot dip galvanizing was introduced to the steel window further adding to their ability to stand the test of time. Due to the customization of steel windows, there were many manufacturers making many different styles. In 1964, however, a set of profiles were standardized in the market. Today you can see many of these historic rolled steel windows still in place. If steel windows are regularly maintained, they can last another 100 years into the future.
While commercial windows continued their success in the commercial world, the residential world went a different direction. After wrought iron was fazed out Wooden windows became the favorable style in many homes.
“In it’s heyday, the steel window wasn’t a trend or fashion, it was a window of necessity.”
