Reclaimed materials for acoustic B2B solutions
CIRAMAT manufactures high-performance composite mineral acoustic boards SonoBloc™ made from reclaimed construction materials. Calibrated for Class A2 fire protection and superior acoustic damping in doors or architectural systems.
Engineered for acoustics, safety, and circularity
Our innovative mineral composite panels combine reclaimed construction mineral resources with state-of-the-art composite engineering to match the highest in class acoustic and fire performance, providing manufacturers high-value acoustic solutions for doors and wall partitions.
Acoustic door fillers
Functions as both sound remitter and spring board in one system, delivering exceptional sound transmission loss inside acoustic doors.
Circular mineral feed
Manufactured using mineral by-products recovered directly from construction projects, dramatically decreasing embodied carbon.
Class A2 fire rating
Engineered to satisfy stringent non-combustibility requirements, ensuring reliable fire safety across demanding commercial builds.
Swiss engineering
CIRAMAT emerged to rethink how building materials can be reused and upgraded. Based in Delémont, Jura Canton, Switzerland, our team transforms demolition debris into certified, high-grade mineral acoustic panels that empower builders to reach both net-zero and acoustic goals without compromise.
A dual-action acoustic core
Unlike traditional single-purpose acoustic insulation, SonoBloc™ acts as a sound blocker and resilient spring board simultaneously. This unique mechanical damping profile maximizes acoustic isolation within slim, lightweight door profiles.
"Integrating SonoBloc™ into our certified door lines allowed us to boost our acoustic ratings while significantly reducing our product line's carbon footprint."
Door manufacturing partner
"Finding a Class A2 fire-resistant core that is sourced directly from recycled building rubble represents a monumental leap forward for circular architecture."
Acoustic engineering consultant
"SonoBloc's consistency and calibrated tolerances streamline our lamination process and ensure dependable decibel ratings every time."
