Weibel Mauerkasten

From the jury's assessment

The Weibel wall vent is a loss-free wall vent that implements the principle of burst ventilation consistently. Its multi-chamber construction suits the thermal insulation of modern buildings. The wall vent closes airtight, watertight and sound-insulating thanks to its flexible lid seal. The electric drive sits inside the housing and can be controlled automatically, manually or by relay.
