Sirpa

Our bio-foam with acoustic properties.

For a quieter, greener future

Our lightweight acoustic foam delivers top-of-the-line acoustic absorbance and good fire resistance properties with environmental responsibility at its core. By combining Finnish pine fiber with bio-based agents and our material science expertise, we have developed a versatile bio-based foam material that can be utilized in a range of applications.

A customized solution

Our acoustic bio-foam can be cut into different shapes and sizes, and painted or covered with fabric to achieve the look you’re going for. Better moisture resistance and improved mechanical strength can be achieved by modifying material composition. Contact our team to discuss how the material can enhance your products while supporting your sustainability objectives.


Why our foam?

  • Sustainably Sourced – Made from renewable wood pulp fibers, supporting a circular and low-impact materials cycle.
  • Biodegradable & Recyclable – At end-of-life, panels can be safely composted or recycled, unlike synthetic acoustic foams.
  • High Acoustic Performance – Excellent sound absorption and noise reduction, ideal for offices, schools, studios, and homes.
  • Lightweight Yet Durable – Strong fiber structure provides rigidity and stability while remaining easy to handle and install.
  • Aesthetic Versatility – Can be molded, dyed, or textured to fit architectural and interior design needs.
  • Low VOC & Non-Toxic – Safe for indoor air quality, with no harmful off-gassing often associated with synthetic materials.
  • Carbon Smart – Wood pulp stores carbon during its lifecycle, helping reduce the overall carbon footprint of buildings.
  • Cost-Effective – Competitive with conventional acoustic materials while offering superior sustainability credentials.
  • Customizable – Can be engineered into different densities, thicknesses, and finishes for tailored acoustic and design solutions.

Acoustic Applications

Our acoustic bio-foam made of wood-based materials can be utilized as standing room dividers, wall and ceiling acoustic panels, furniture and even building insulation.
