Why Aluminium? Aluminium has many design advantages over standard PVC allowing larger glazed areas with reduced sight lines to take full advantage of views. It is durable and light weight with a lifecycle measured in decades rather than years. Aluminium is 100% recyclable and loses none of its material qualities in the process. Marco uses suppliers such as Smart Architectural Aluminium who are fully committed to working towards a greener, more sustainable environment and 100% carbon neutral production.
