About the products
Søuld’s acoustic products are made from eelgrass — a natural, carbon-binding material — to create pleasant indoor environments that support human health and well-being. The material’s organic properties stimulate the senses and bring warmth and tactility to interiors.
Our products deliver high acoustic performance and meet leading fire classifications, combining natural material qualities with documented technical performance. Our collection includes Acoustic Panels and Acoustic Design Solutions ready to be installed in interiors.
Sustainability
A natural product
Søuld’s acoustic panels are made from eelgrass gently collected along the Danish coast after it washes ashore. By removing the eelgrass from the shore, biomass producing climate-damaging greenhouse gases such as CO₂ and methane is removed. At the same time, the carbon captured during growth is stored within the material.
A third-party verified EPD confirms that more carbon is bound in Søuld Acoustic Panels than emitted during production (A1–A3). Søuld has achieved Cradle to Cradle Certified® Gold across Material Health, Circularity and Full Scope (version 4.1).
Built on a legacy
The history from Læsø
Søuld’s acoustic products are rooted in a 400-year-old Danish building tradition, where eelgrass was used to create durable, protective homes. On the island of Læsø, eelgrass washed ashore after storms and was gathered, dried and woven into roofing by local craftspeople. Naturally rich in salt, the material proved highly resistant to fire, moisture and decay—qualities that allowed these structures to last for centuries.
This knowledge has been carefully revisited and refined. Today, Søuld translates this heritage into contemporary acoustic solutions, bringing an abundant natural material into modern architecture.
Biodiversity
A natural product
Biodiversity is central to how we work with eelgrass. By gently collecting eelgrass that washes ashore naturally along the Danish coastline, we reduce the return of nutrients to the sea and support balanced coastal ecosystems. Independent analysis confirms that our activities do not harm local biodiversity, while contributing to maintaining ecological integrity and extending carbon storage in our acoustic panels.
