DUCO has a wide range of natural air intake grilles for new buildings and renovation projects. For every building location - installation on glass, intermediate rail (transom mounting), on the top op the window frame or as compact transom mounting - DUCO has the right kind of architectural grille.
When self-regulating ventilation grilles are used, the air flow is naturally supplied by an adjustable damper on the one hand and a self-regulating damper on the other hand. The self-regulating damper works mechanically and ensures that the ventilation volume remains the same as the wind increases. The result: a pleasant comfort!
