A mechanical threshold that is milled into the bottom edge of the door leaf. When the door closes, the button on the automatic threshold is pressed against the side jamb of the frame, so that the sealing lip closes tightly against the floor.
The automatic threshold provides sound reduction of up to 48 dB and also works as a smoke seal. See the European approval for smoke sealing and sound reduction, as well as the installation instructions, under related files.
