Rockwool AFB (Acoustical Fire Batt) is a batt insulation product designed for wall and floor systems where acoustical performance and fire resistance are the primary concerns. Lightweight and noncombustible, it's the kind of product that quietly does the job—no drama, just better sound and safer walls.
