Description
Our micro-perforated rock wool roof sandwich panel is a roofing solution specifically engineered for environments requiring high levels of sound absorption. Featuring a rock wool core—a material with inherent sound insulation properties far superior to traditional options like polyurethane or cork—the panel incorporates a micro-perforated surface or perforated inner strips. This design delivers a dual effect of sound absorption and insulation, effectively eliminating echoes and reverberation to create a cleaner acoustic environment.
Whether exposed to heavy rain, strong winds, extreme heat, or freezing cold, this sandwich panel offers stable, reliable thermal insulation, maintaining a comfortable indoor temperature across diverse outdoor settings and challenging climates. A range of surface coating options is available to resist environmental erosion and extend the product’s service life.
Thanks to its exceptional sound-absorbing and noise-reducing capabilities, this rock wool roof panel—featuring micro-perforations or internal perforated strips—is an ideal choice for high-noise venues such as sports centers; it absorbs internal noise while preventing sound leakage to the outside. The exterior features a “triple-rib” profile paired with specialized trim accessories, ensuring excellent acoustic performance alongside a refined, aesthetically pleasing finish for both interior and exterior surfaces.
Beyond sports arenas, this Rock Wool Acoustic Roof Panel is widely used in churches, bars, nightclubs, concert halls, performance venues, and event spaces. It also serves as an ideal sound-insulating roofing solution for mechanical rooms, compressor rooms, outdoor sawing areas, and sites housing high-noise machinery.
In addition to its superior sound-absorbing qualities, the Rock Wool Acoustic Roof Sandwich Panel offers excellent fire resistance, serving as a reliable fire barrier. It is, in essence, a comprehensive rock wool roof sandwich panel solution that combines noise control with fire safety.
Key Performance Features
This Rock Wool Insulated Acoustic Roof Panel utilizes high-density rock wool as its core material, leveraging its natural porous structure to achieve excellent sound insulation. Combined with a micro-perforated or perforated strip design on the inner panel, it significantly boosts the sound absorption coefficient and effectively controls indoor reverberation time.
Technical Advantages:
- Weather Resistance: Compatible with various high-standard coatings; UV-resistant and corrosion-resistant, making it suitable for harsh outdoor climates.
- Structural Mechanics: The external triple-rib profile enhances the roof’s load-bearing capacity and drainage performance.
- Thermal Performance: Low thermal conductivity provides superior thermal insulation compared to traditional materials.
- Fire Rating: Meets Class A non-combustible standards, making it an ideal architectural panel that combines acoustic functionality with fire-resistant properties.

Frequently Asked Questions
What is the fire rating of your Rock Wool Insulated Acoustic Roof Panels?
Our rock wool roof panels achieve an A1 Non-Combustible rating under European EN 13501-1 standards. Made from high-density basalt fibers with a melting point exceeding 1000°C, the core material does not emit toxic fumes, melt, or produce flaming droplets during a fire.
How does the panel achieve high sound absorption and sound insulation at the same time?
The panel utilizes a dual-action acoustic architecture:
- Sound Absorption (NRC up to 0.85): The inner metal liner is micro-perforated. Sound waves pass through these micro-holes directly into the porous rock wool fiber matrix, converting acoustic energy into thermal energy via internal friction.
- Sound Transmission Loss (Rw / STC up to 35 dB): The solid, high-gauge outer metal sheet combined with the high-density rock wool core acts as a barrier, preventing external noise (such as rain impact or traffic) from entering the building envelope.
How do you prevent water leaks at the roof panel joints?
Can these panels be installed using standard roofing tools and purlins?
Yes. The panels arrive cut-to-length according to your structural layout and are designed to mount directly onto standard steel purlins. Installation requires standard power tools, lifting clamps, and self-drilling screws. Detailed shop drawings and installation guidelines are provided with every shipment.
What routine maintenance is required after installation?
Outer Roof surface: Inspect twice annually to clear accumulated leaves or debris from gutters and check flashings around roof penetrations.
Inner Perforated liner: Occasional dry dusting or light compressed air blowdown is sufficient to keep the micro-perforations clear in dusty industrial environments. Avoid high-pressure water spraying directly onto the inner perforated liner.
