Glass Design Curtain Wall for Maximum Transparency

Glass posts for a visual reduction of the face width of curtain walls

heroal C 50 GD is a design study which represents a true highlight when it comes to curtain walls. The concept 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.

Advantages for fabricators using glass posts for curtain walls

For fabricators, the advantage lies in the system’s reliability: heroal C 50 GD is based on the established curtain wall system heroal C 50. The fabricator orders the modular glass to measure, which heroal delivers to ensure that fabricator can continue working with the products as usual. Consequently, a seal certification is no longer required for the fabricator. The glass fin can be reversibly removed through the clear separation plane, for example in order to change the design. Apart from advantages of design due to optimized interior views, there is also the advantage of being able to integrate textile sun protection.

Unlike other comparable systems, a controlled ordering process is planned for heroal C 50 GD. No individual production for provided dimensions are required for single construction projects, which significantly reduces delivery times.
