Bare Mineral Wool Slab |
Wood Wool Board |
Perforated Acoustic Panel (Composite) |
|---|---|---|---|
|
Acoustic mechanism |
Porous fiber friction only |
Porous wood-cement matrix, mid-band bias |
Tuned perforation + cavity + bonded absorber (Helmholtz + porous) |
|
Typical NRC |
0.85–0.95 as raw core, but drops sharply if exposed to dust/compaction |
0.60–0.85 depending on thickness and binder density |
0.70–0.95 with matched cavity and core density |
|
Frequency tuning |
Fixed by thickness/density, no face tuning |
Limited; biased mid-to-high |
Precise via hole diameter, pitch, open area and cavity depth |
|
Fire classification |
A1 core, but facing/fixings often undefined |
Typically Class B1 / B-s1,d0, not always A1 |
A1/A2 achievable as a sealed composite assembly |
|
Surface integrity |
Open fibrous face, friable edges |
Rigid, textured, impact-tolerant |
Closed metal skin, dust-tight, washable |
|
Fiber/dust release |
Bare mineral wool slab acoustic absorption fiber release — loose fibers migrate into occupied air if unfaced |
Minimal, encapsulated in cement binder |
Zero fiber release due to metal face + non-woven backer |
|
Moisture / washdown |
Absorbs humidity, sags, loses NRC, mold risk in humid zones |
Moderately moisture-tolerant, but wood wool board impact resistance wet cleaning limitation applies — not for steam/VHP/wet scrub |
Powder-coat / PVDF face survives washdown, sweat, condensate |
|
Impact & abrasion |
Fragile, crumbles on contact |
High impact tolerance for ball zones |
Good with 0.5–0.6 mm steel; dent-resistant, not ball-bat proof |
|
Cleaning protocol |
Gentle vacuum only; aggressive wipe shreds fibers |
Dry/vacuum only; saturated mopping stains and swells binder |
Wipe, mild disinfectant, pressure-clean safe |
|
Joint & flanking control |
No integral joint seal; needs separate frame + wrap |
Butt-joint, no acoustic gasket as standard |
Tongue-and-groove + EPDM/acoustic caulk as engineered detail |
|
Decoration / branding |
Utilitarian, grey/brown, rarely client-facing |
Warm, raw-architectural, strong for sports/auditorium looks |
RAL, wood-grain, micro-slot, logo perforation available |
|
Procurement risk |
Bare mineral wool slab acoustic absorption fiber release + hidden fire-file gaps if left unfaced |
Wood wool board impact resistance wet cleaning limitation in food/pharma/equipment-wash zones |
Lowest acoustic-file risk when core density, perforation map and seal certs are enforced |

Wipe, no fiber event, no sag |
15–25 yr service window |
Lowest lifecycle disruption in regulated spaces |
The high NRC composite acoustic panel lifecycle cost case is strongest wherever fire inspection, hygiene audit, equipment washdown or reverberation-spec handover is contractually tied to acceptance.

Exposed fibrous face, cheapest quick fill |
Bare mineral wool slab (exposed) |
Enclosed perforated composite |

Ball impact + raw-architectural look, dry venue |
Bare mineral wool slab |
Wood wool board (zoned, dry only) |

A1 fire + washdown + dust-free + tunable NRC |
Bare mineral wool / most wood wool |
Perforated Acoustic Panel (composite, sealed) |

KTV/cinema low-mid control + finish freedom |
Unfaced foam/loose wool |
Slotted perforated composite + cavity-tuned core |
All three materials absorb. Only the perforated composite converts absorption into a sealed, fire-classed, washable, auditable wall system.
