HUECK Lambda SA I
Sound-proof windowHueck System GmbH & Co. KG
Conventional sound-proof windows only reduce sound pressure when closed. Moreover, being completely cut off from outdoor noise results in a feeling of isolation for many people and causes noises from the building’s interior to seem more intense. The Lambda SA I from German manufacturer Hueck is a genuine alternative. This innovative window solution achieves sound absorption figures of up to 31 decibels even when partially open for ventilation.
