Architectural aluminium re-invented for Surrey and South West London homes

Original metal windows date back to medieval times, made from wrought iron by blacksmiths. It wasn’t until 1856 that a new production process for hot-rolled steel was introduced. Steel windows were widely used in construction from 1912 to 1964, where the window manufacturer ‘Crittall’ became the most well-known ‘classic’ steel casement window manufacturers of their time. The drawbacks of steel windows came in the form of their weight and cost. Aluminium was only considered and utilised for window manufacturing in the 1950s, as it had become relatively cost-effective as well as being lightweight yet strong, low maintenance and incredibly recyclable.
