Aluminium Series

Slim-Line Windows

Narrow sightline aluminium profiles, thermally broken, engineered for a minimal facade with maximum glass.

Slim-Line Windows
Aluminium Series

Frames that get out of the way of the view.

Slim-line windows use a thermally-broken 6063-T5 aluminium profile to hold a narrow sightline without giving up thermal performance or structural strength.

This system is specified where the architectural intent calls for maximum glass area — floor-to-ceiling openings, corner windows, and modern facades.
