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.
