fecodoor Air

Sound-insulated ventilation function integrated directly into the door leaf

In buildings with structurally active concrete ceilings (BKT), door elements are increasingly taking on additional functions relating to building physics. Where suspended ceilings for ventilation ductwork are absent, the door area ensures the necessary air exchange between the room and the corridor without compromising acoustic privacy within the room.

The fecotür Air airflow door element relocates this ventilation technology entirely into the wooden door leaf. This offers a decisive design advantage: all adjacent fixed glazing and solid wall surfaces remain unaffected by ventilation fittings. Instead, the flow-optimised air exchange takes place concealed via discreet, front-facing slotted joints directly in the door.

fecotür Air reliably meets the requirements of sound insulation class 2. When the air flow rate is reduced by the ventilation system, the door unit achieves sound insulation of up to R_w,P = 40 dB – ideal for undisturbed work in confidential offices and meeting rooms.
