Feed-through vents

Fresh air must be able to circulate freely between the different rooms indoors. So Duco developed the DoorVent, an acoustic feed-through vent that is installed in the internal doors.

A controlled air flow contributes greatly to the optimum functioning of the ventilation system. DoorVent provides the desired amount of air flow between the different rooms of a building or dwelling. Unlike cracks under the door, DoorVent thereby avoids draughts and attenuates intrusive noise.
