Modern room concepts are becoming increasingly larger and are designed to be open. The resulting background noise has a very detrimental effect. High rooms, smooth concrete walls and exposed ceilings may appear airy and light, but they lead to a growing need for acoustic improvements. With the design of walls made of real preserved mosses and plants, completely new possibilities open up for a design-oriented room layout. With a sound absorption coefficient of up to 60 %, our wall coverings made of moss provide noticeably improved room acoustics with an unmistakable natural character. Thanks to its natural properties, the prepared moss also stores moisture and releases it again when the air is too dry. This creates a pleasant and constant room climate.
