The first steel windows were manufactured by Francis Henry Crittall, who took over the Braintree based CRITTALL® window business from his brother in 1884. The distinctive steel windows were hugely popular after the First World War when there was a demand for quality, durable windows.
One of the major problems with using steel as the framework for windows and doors can be the prohibitive cost. Compared to using aluminium as the framework, other potential hurdles to overcome when considering steel are thermal compliance to current Building Regulations and very long lead times.
