Aluminium is not only light, but it is incredibly strong, durable and corrosion proof. It does not expand or contract in hot or cold weather and will not rot, rust flake or peel so requires very little maintenance. Because Aluminium is slimmer than some other window materials, it means you get more glass and less frame, which translates to more light into your home and greater views of the outside. It can be coloured to finish and is thermally broken to make sure that it lives up to customers expectations in search of comfort and heat retention within their home.
