The use of wrought iron dates back to ancient civilizations. Initially valued for its utility in tools and weapons, it became increasingly popular for decorative purposes during the Middle Ages. Blacksmiths began to showcase their skills by crafting exquisite ironwork that highlighted the beauty of this malleable material. During the Renaissance, wrought iron saw a revival as artists and craftsmen embraced its capacity for intricate designs and embellishments. This period marked the transition of wrought iron from a mere crafting material to a significant art form.
It is worth mentioning that aluminium window joinery has not always been so popular. Until recently, it was regarded as cold joinery, and there was a lot of truth in that. Therefore, whilst aluminium was used in warehouses, offices and shops, it was not used in single-family homes. Nowadays, the situation is quite different – of course, aluminium does not feel as ‘warm’ as wood and, when the frame comes into contact with a warm hand, it will feel cooler than, say, pine. This is all due to the fact that aluminium does not have as much ability to absorb heat. However, we should add that in reality its temperature will often be the same as that of the aforementioned wood.
