In the structural silicone facade system, no aluminum profile is visible from the outside, and there is a 17 mm wide and 15 mm deep gap in the glass joints. Since the sealing between the glass panels is provided with double EPDM wick, no sealing silicone is applied between the panels. Thus, shadow formation between the glass panels is prevented. When desired, any selected glass panel (without revealing which one opens from the outside) can be turned into a hidden wing. Component silicone and silicone-compatible sealing tape are used between the glass and aluminum panel, and between the two glasses in double glazing.
