Aluminium has gained itself a place alongside other materials such as brick, concrete, steel and timber as a building material with proven characteristics and behaviour. The unique combination of properties, versatility of form, light weight and durability have made aluminium a building material that is ideal in modern construction. Today’s designs of tall, strong but light-weight commercial buildings make important use of aluminium cladding and curtain walling with its material benefits coupled with the ease and speed of erection. Domestic houses incorporate double-glazed aluminium window frames that offer a lifetime of attractive and efficient service.
