Acoustic Ventilation Grille
Silendo door grille is used when the gap between the bottom of the door and the floor closed or sealed, for example by a drop seal, but ventilation remains necessary. Apartments and houses with a recirculation system usually have a wide openings or gaps between the floor and the door to eliminate overpressure in rooms. This opening composes a sound leak that optimally is covered by means of a drop down seal. The Silendo door grille prevents overpressure and prevents a sound leak.
