Aluminium's structural strength allows for significantly slimmer frames than UPVC or wood while still safely supporting large glass panels — meaning more visible glass area and better natural light for the same opening size.

Slim sightlines are a defining feature of contemporary architecture — clean, minimal frame lines that let the view and the glazing take center stage rather than the frame itself.
This strength-to-thickness ratio also enables large-span sliding and lift-and-slide systems that would not be structurally practical in bulkier materials.
The trade-off is thermal performance — slim aluminium conducts more heat than UPVC, so thermal-break profiles are recommended for extreme climates or heavily glazed facades.
