Product Overview
Rockwool Sound Absorbing Panels use a porous rock-wool fiber layer to absorb sound inside a room or enclosure. Their main job is to control reflected sound and reverberation, rather than simply add mass to a separating wall.
They are used in recording spaces, meeting rooms, classrooms, hospitals, municipal interiors, machinery enclosures, and other rooms with hard finishes where reflected sound needs to be reduced at wall or ceiling surfaces.
Key Advantages
Sound Absorption Coefficient Above 0.8
Product data specifies a sound absorption coefficient above 0.8. In rooms with hard floors, ceilings, glazing, or metal surfaces, the treated panel surface absorbs a large share of incident sound energy and reduces the repeated reflections that build reverberation.
Open Mineral-Fiber Dissipation
The rock-wool core has an interconnected fiber network. As sound moves through it, friction dissipates part of the acoustic energy. In studios, classrooms, and meeting rooms, this helps reduce the repeated reflections that can affect speech clarity.
Mineral Acoustic Core Without Foam Fill
The absorption layer uses rock wool rather than a soft plastic-foam acoustic fill. For public, industrial, and technical spaces that restrict combustible interior materials, this provides an acoustic treatment based on inorganic mineral insulation.

Quality Control
- Rock-wool material and panel facings are checked before production for material identity, fiber-core consistency, sheet thickness, and visible surface damage. Panel dimensions and construction are controlled in accordance with GB/T 23932. Process records, inspection points, and corrective actions are managed in accordance with ISO 9001.
- Production checks cover mineral-fiber uniformity, bond continuity, face alignment, and edge geometry. Inspectors look for local crushing or open voids, and panels with inconsistent core distribution are separated before final inspection because density changes can affect the acoustic response.
- Finished panels are checked for dimensions, flatness, bond integrity, and core consistency. Acoustic sample testing can be used to verify the specified absorption behavior. A 100% visual inspection is completed before packaging, and third-party inspection is accepted when included in the order.
FAQ
Q: How is Rockwool Sound Absorbing Panel packed for export?
A: Panels are wrapped with PE film and protected with L-shaped cardboard or plastic corner guards.
Q: Which shipping terms are available?
A: EXW and DDP are available.
Q: Where should sound-absorbing panels be placed in a room?
A: Place them on the wall or ceiling areas identified by the room-acoustic layout, especially major reflection zones around the sound source and listening area.
Q: Can the active acoustic face be covered with an airtight decorative sheet?
A: No. A dense airtight cover blocks sound from entering the porous mineral-wool layer and reduces absorption at the treated surface.
