Aluminium system
Cortizo
Contemporary, architectural, strong in large sliding and minimal-frame work.
Overview
About Cortizo
Cortizo is frequently specified where the brief is large glass and slim frames. It appears on contemporary extensions, rear elevations and architect-led projects.
Aluminium suits these applications because the frames can stay slim while carrying large, heavy glass units.
Ownership: Spanish aluminium systems group supplying windows and doors across Europe and the UK.
