Rock wool acoustic roll is a professional sound-absorbing rolled product specially developed for noise control scenarios. With high-quality basalt fiber as the core base material, it achieves efficient sound energy absorption and attenuation by optimizing the fiber pore structure. Rock wool acoustic roll is widely used in the field of acoustic renovation. Compliant with the ISO 3744 acoustic standard, the product can effectively reduce environmental noise by 15-30dB. It is suitable for industrial and construction scenarios requiring noise reduction protection, and is an ideal material that balances sound absorption effect and safety performance.
Core Performance
Acoustic Performance: Within the frequency range of 250-4000Hz, the sound absorption coefficient is ≥0.7, showing remarkable absorption effect on various noises such as equipment operation sound and air flow sound. Certified by ISO 3741, the noise reduction can reach 12-25dB.
Fire Resistance Performance: Made of inorganic silicate fiber, it has a fire rating of Euroclass A1, which is non-combustible when exposed to fire and does not release toxic gases. The maximum fire separation time can reach 120 minutes (in line with UL 1043 standard).
Thermal Insulation Performance: With a thermal conductivity as low as 0.040 W/(m・K), it has both sound absorption and thermal insulation functions, realizing "one material for multiple purposes" and reducing comprehensive costs.

Product Advantages
Efficient Sound Absorption: With a porosity of over 90%, sound energy is quickly dissipated through fiber friction, and the sound absorption effect is 30% better than that of traditional sound-absorbing materials.
Flexible Installation: It has strong flexibility, can be bent to fit curved structures, no fiber shedding after cutting, and tight joints without acoustic leakage.
Durable and Reliable: It is resistant to mold and moth, performs stably in the environment of -20℃ to 70℃, and has no attenuation of sound absorption efficiency after long-term use.
FAQ
Q: 1.What is the difference between it and ordinary rock wool rolls?
A: It has a higher fiber density (100-140 kg/m³) and an acoustically optimized pore structure. Under the same thickness, the sound absorption coefficient is increased by 40%, and the high-frequency noise absorption performance is more prominent.
Q: 2.What precautions should be taken during construction?
A: Construction personnel must wear protective masks and gloves to avoid inhaling fibrous dust. After installation, the construction site should be cleaned up in a timely manner, and the remaining materials should be sealed and stored to prevent fiber scattering.
Q: 3.Do you provide after-sales technical support for installation?
A: Absolutely. We offer a detailed installation manual including construction steps and precautions. If you encounter technical problems during installation, our professional team will respond within 72 hours and provide online guidance or on-site assistance if needed. We also provide product quality traceability through batch numbers to ensure accountability for any usage issues.
