heroal C 50 GD is a system solution which represents a true highlight when it comes to curtain walls. The system benefits from the idea of reflection in two ways: the view width of the mullion is visually reduced on the inside while the installation depth of the mullion is decreased on the outside. This effect is possible thanks to the use of a glass fin which takes on the static tasks of the traditional aluminium mullion. Architects and planners gain access to a world of new possibilities for creating maximum transparency – even on large surface areas up to a height of 5 metres. Almost limitless design choices are created by the optional lighting of the glass fin with LED, the design of the fin with individually decorated panels, the coating of the aluminium components with especially durable and highly weather-resistant heroal hwr powder coating in all RAL colour shades, the colours of Les Couleurs® Le Corbusier and heroal SD surface finishing.
