Acoustic Mats

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.

Performance

SOUND ABSORBING — As a result of the material’s porous structure, Søuld’s Acoustic Mats deliver an exceptional sound absorption across a wide range of frequencies. By heavily dampening noise, Søuld’s products help to create restful and productive atmospheres within residential, industrial and public spaces, contributing to human health and well-being.

As well as reducing ambient noise, Søuld’s products bring calm to interiors through their simple, honest forms.

2.
Derived from the sea, the eelgrass fibres naturally contain high amounts of salt which resists fire.

FIRE PROOFING — Søuld’s Acoustic Mats are crafted from eelgrass which is naturally impregnated with sea salts to result in products with an imbedded fire protection. For increased performance, Søuld combines the eelgrass with a natural and non-toxic flame-retardant. Søuld is currently type-approved as protective cladding with a class C-s1,d1 and will reach class B-s1,d0 by second half of 2022.

CARBON STORING — Søuld is made from a sea plant that reproduces itself annually, washes ashore during autumn storms and is dried on nearby fields by the sun and wind. Eelgrass binds large amounts of CO₂ during its growth and if left to decompose, it would release CO₂ back into the atmosphere. By safely storing this CO₂ in durable building materials, Søuld’s products serve as carbon sinks which result in a highly positive climate impact. Our certified EPD confirms there is more CO₂ bound in eelgrass than what is emitted during Søuld’s production of the final product (A1-A3).

ROBUST & DURABLE — Søuld acoustics are robust and durable. The plants’ growth in salt water adds a natural impregnation to the fibres which impede the growth of mold and bacteria. This enables a long product lifetime and contributes to a healthy indoor climate.

MOISTURE REGULATING — Søuld products act as an effective humidity regulator. They absorb excess indoor humidity and release it when the humidity levels drop, thus maintaining an optimal level. This natural humidity control contributes to a pleasant indoor climate that promotes comfort and health.

6

LOW-EMISSION — Søuld’s products contain no harmful chemicals or additives, and emissions from the products are extremely low. This contributes to improved indoor air quality that supports health and well-being. Additionally, our products are classified as low dust emitting, making them well-suited for sensitive environments.

Søuld’s Acoustic Mats retain the evocative quality of the plant they’re made from to bring nature indoors.

NATURAL CHARACTER — Humans, climate and nature are inseparable and natural materials allow us to slow down and feel at ease. Søuld brings an honest expression of nature inside, imparting warmth and a sense of pre-industrial humanity. As eelgrass is a living material, unique tonal variations are seen each season from muted greens to warm browns. Watch the expression shift as light and weather conditions change and colours take on more character as a subtle patina emerges over time.

FLEXIBLE SOLUTIONS — Søuld is characterized by tactility and simple design solutions that seamlessly integrate with many contexts and needs. The material is heat pressed into flat, uniform mats allowing the products to be cut in various shapes and sizes, making design customizations easy. The products are simple to install using adhesive or screws, and they’re scalable to suit interiors of any size.
