Our rock wool core is specifically designed for interior metal sandwich panel partition systems, serving as the core material for fire compartmentation and acoustic separation. Featuring a high-absorption fiber structure, it delivers excellent acoustic performance, effectively blocking sound transmission between rooms for enhanced privacy. Meeting Class A non-combustible fire standards, it does not burn or emit toxic fumes, meeting building fire compartment requirements. Lightweight and high-strength, it adds minimal floor load, making it ideal for industrial plants, office buildings, and cleanrooms.
