We develop the Acoustic Partition Rock Wool Board to address noise control in buildings, using high-quality basalt fibers processed into a porous structure. This board leverages the sound-absorbing properties of interconnected fiber gaps, converting sound energy into heat energy to reduce noise transmission. It is designed for partition walls, ceilings, and sound barriers, balancing acoustic performance with fire safety and environmental friendliness. Every board is tested for sound absorption coefficient and fire resistance, ensuring it meets the strict requirements of commercial and public buildings.

FAQ
Q: What thickness of Acoustic Partition Rock Wool Board is needed for a 45dB noise reduction requirement?
A: For partition walls, a 50mm thick board (density 140 kg/m³) paired with double gypsum boards can achieve 40-45dB noise reduction. For higher requirements, we recommend 60mm thick boards.
Q: Can this board be used in wet areas like bathrooms?
A: Yes. With a hydrophobicity rate of ≥95.0% and volumetric moisture absorption rate ≤0.2%, it resists mold growth. However, we suggest installing a moisture barrier on the surface to prevent direct water contact.
Q: Is the board easy to cut and install on-site?
A: Absolutely. It can be cut with a utility knife, and weighs only 7.2-11.5 kg per square meter (for 50mm thickness), making on-site installation labor-saving. We recommend using self-tapping screws with washers for fixation.
