Sappa Panels are CO₂-negative acoustic panels made from industrial hemp shives and an ecological mineral binder. Developed as a circular alternative to conventional acoustic systems, Sappa combines high-performance sound absorption with a radically reduced environmental footprint.

The panels are manufactured without cement, synthetic resins, or fossil-based additives. During growth, hemp absorbs significant amounts of CO₂, which remains stored within the material. The binder mineralizes over time, creating a durable yet fully recyclable composite. At the end of their life cycle, Sappa Panels can be crushed and returned to the biological or mineral cycle.

Beyond sustainability, Sappa offers a distinctive, natural aesthetic. The visible hemp texture creates warm, tactile surfaces that improve interior atmosphere while enhancing acoustic comfort. The panels regulate humidity, are vapor-permeable, and contribute to healthy indoor climates. Sappa is designed for architects and designers seeking materials that unite performance, material honesty, and ecological responsibility. It represents a shift from technical acoustic products toward regenerative building components – proving that climate-positive materials can also deliver architectural quality and refined design.
