Comfort and Smoke Ventilation for Structural Glazing

Optimise the indoor climate and occupant safety with comfort and smoke ventilation.

The electrically operated openings ensure both optimal comfort and efficient smoke ventilation. Offering natural ventilation through the roof and reduced smoke accumulation inside burning buildings, the ventilating openings are designed to optimise indoor comfort and smoke ventilation in accordance with EN 12101-2.

Louvres can be double-glazed or insulated aluminium panels.
