The History of Steel Windows

Steel windows have long been an architectural staple and for good reason. They’re not only sleek and versatile, but have always been on the cutting-edge of design. As a modern look that stands the test of time it’s hard to believe they can be traced back to the medieval era. As purveyors of steel windows and doors, it only made sense that we paid homage to the history of this beautiful product. 

Enter the Blacksmith. A craftsman who started working with iron before steel came along. Using their skills to create iron windows for churches or the well-off their craft became a staple in luxury buildings and homes. The windows were works of art that flaunted a distinct look but the energy and thermal insulation was terrible. During this period, glass was expensive and clear glass could only be crafted in smaller panes. These fabrication limitations led to the creation of a window frame that could hold multiple planes of glass, and glazing bars were born. 

As time went on, iron windows became old news to the wealthy. They had their eyes set on timber frames since they were viewed as more elegant. This change in taste opened the metal windows market to a wider group of builders who started using them in more modest homes. During the mid-18th century, another rise in metal window popularity began. More precise casting methods were developed and allowed for iron to be used in the construction of the sash window. Factories began to sprout up as humans entered the Industrial Revolution. Metal windows could now be produced in a controlled factory environment which allowed for a greater choice of style and design.

Because of the new innovations, metal windows were incorporated into commercial buildings.  Smaller builds like cottages also started using them in their builds because of the security and ventilation abilities.

Fast forward to the end of the Industrial Revolution when our beloved steel windows became a possibility. A man by the name of Sir Henry Bessemer developed a process for hot rolling steel opening up the doors to a new metal window. With this new technique, Great Britain became a mass supplier of steel and steel windows exploded in popularity.

In modern times, steel windows have seen another resurgence and their gain in popularity is no surprise. We’re huge fans of the medium and love the possibilities that innovations in thermally broken systems have created in the world of design.
