The incredible high strength-to-weight ratio of aluminium makes it possible to design light structures with exceptionally stability. The use of aluminium provides architects with the means to meet required performance specifications, while minimizing expenditure on foundations. Thanks to the metal’s inherent strength, aluminium window and curtain wall frames can be very narrow, maximizing solar gains for given outer dimensions. In addition to which, the material’s light weight makes it cheaper and easier to transport and handle on site and reduces the risk of work-related injury.
