Acoustic treatments are crucial in shaping the atmosphere of a space. Often, poorly integrated tiles disrupt the aesthetic, while omitting them can result in uncomfortable acoustics. Enter Spinneybeck’s Søuld Eelgrass line, offering a solution that celebrates natural materials. This innovative range now features the modular Søuld Fragments.
From shoreline to interior elegance
The Søuld collection, crafted in partnership with Danish manufacturer Søuld, utilizes eelgrass—a sustainable marine plant found along Denmark’s coastlines. After reaching the end of its lifecycle, this green material is collected and processed into acoustic solutions that infuse spaces with warmth and texture.
Søuld Fragments repurposes the offcuts from producing larger mats and boards. These remnants are transformed into modular tiles that boast rich variation and texture, elevating both appearance and function.

Sustainable sound softening
With a Noise Reduction Coefficient (NRC) rating of 0.70, Søuld Fragments effectively diminish sound in various environments—from bustling offices to cozy homes. This sustainable approach rivals conventional acoustic solutions while reducing ecological impact.
The architectural use of eelgrass is not new. Historically, Danish settlers on the island of Læsø used eelgrass to construct thick, durable thatched roofs, known as “seaweed houses.”

A vision for longevity

“Our vision is to extend the lifecycle of eelgrass through thoughtful product design,” states Tobias Øhrstrøm, the project’s founder. “The goal is to create items with longevity, recyclability, and adaptability for repair and reuse.”
The tiles feature soft, rounded edges with chamfered detailing, offering precision in application. Available in two coordinating styles, they allow designers to create a variety of installation patterns, fitting any spatial need.
