High-density rock wool panels engineered for thermal insulation, sound control, and fire protection in a single board. Manufactured from natural volcanic rock fibers bonded with a thermosetting binder, these panels are non-combustible (Euroclass A1), water-repellent, and chemically inert. Available rigid (high density), semi-rigid (medium density), or fluffy (low density) with compression strength suited to wall, roof, and HVAC applications, and rated for service up to 750°C.
