Our acoustic fireproof rock wool is designed for interior partition walls in residential buildings, offices, and conference rooms where both acoustic comfort and fire safety are critical. Featuring a high-porosity rock wool fiber structure, it delivers excellent sound absorption, reducing reverberation time and enhancing speech clarity. Meeting the Class A1 non-combustible material standard, it does not burn or emit toxic smoke during fire, providing reliable fire protection for occupied spaces.
It is the ideal partition material for modern offices, premium residences, and business meeting rooms.

Rock wool fibers form 3D microporous structure with sound absorption coefficient up to 0.7, effectively absorbing indoor noise and preventing sound interference.
Meets the highest Class A1 non-combustible standard: no burning, no molten droplets, no toxic fumes, providing reliable fire protection for occupied spaces.
Low thermal conductivity effectively blocks heat transfer, reducing HVAC energy consumption and improving indoor comfort.
Lightweight boards are easy to cut and install, perfectly compatible with light-gauge steel framing systems for high construction efficiency.
Inorganic mineral material does not promote mold growth or release harmful gases, ensuring indoor air quality.
