heroal VB Free
Pre-assembled, self-supporting external venetian blind
The Venetian blind prefabricated element heroal VB Free (Venetian Blind Free) is supplied fully assembled on load-bearing guide rails and is ideal for mullion-transom façades such as heroal C 50. heroal VB Free is used where load transfer is only possible via the guide rails. The self-supporting external venetian blind is suitable not only for new buildings but also for retrofitting, as the box is not fixed to the façade or masonry. You can choose between a visible edge cover, a round cover or a blank structural profile. The external venetian blind is mounted to the façade mullion or window using the guide rails. The reinforced guide rails made of extruded aluminum are mounted on reinforced aluminum spacers. Elements with a height of 4,500 mm and a maximum width of 5,000 mm or a minimum width of 582 mm can be realized. The heroal VB Free is controlled at the touch of a button using a radio remote control or manually using a push-button in the wall. The external venetian blind can also be integrated into smart home systems.
