Søuld Acoustic Boards

Made from eelgrass—a natural, non-toxic and CO₂-binding material—Søuld’s acoustics enhance the sensory experience of interior wall and ceiling cladding whilst providing exceptional acoustic performance, health and well-being benefits.

ENGINEERED EELGRASS — The raw material is collected sustainably by Danish farmers and engineered by Søuld into Acoustic Mats that offer exceptional results within indoor environments including restful acoustics, thermal comfort, air humidity stabilization as well as an appealing aesthetic expression.

The mats are approved for safety indoors with high fire resistance, zero harmful chemicals or additives and extremely low emissions—ultimately creating healthy interior atmospheres that support mental and physical well-being. The natural beauty of the eelgrass forges a serene connection to nature indoors and invites a sense of calm and comfort. The material is resilient yet soft to touch—imparting texture, warmth, and a subtle scent that recalls the sea.


Søuld’s acoustics represent a sustainable alternative to help architects, designers and builders reduce the environmental impacts of construction. Søuld’s engineering of the CO₂-binding eelgrass fibres results in building 
materials that act as a carbon sink by locking CO₂ in the material over the building’s lifetime. Søuld’s products are responsibly produced in Denmark and designed to be be fully circular with the lowest environmental impact possible.

With their simple, modern aesthetics, Søuld’s Acoustic Mats are proportioned for easy interior application and are fully customizable to suit residential or commercial spaces of all natures and scales. The mats are convenient and fast to install, and their superior quality provides lasting comfort.
