An Insulated Cleanroom Panel is a perforated, sound-absorbing acoustic wall and ceiling panel — a micro-perforated metal facing over a high-density rock wool core that absorbs noise while it insulates, built to a ≤ 2 mm/2 m flatness tolerance. Key advantages:
An insulated cleanroom panel in this configuration is an acoustic sound-absorbing board: a micro-perforated metal facing bonded to a high-density rock wool core. Sound waves pass through the perforations and are dissipated inside the porous mineral core, so the panel absorbs noise and reduces reverberation instead of simply reflecting it — while the same core delivers thermal insulation and an A-grade non-combustible rating.
To keep it suitable for controlled environments, the perforated face is backed with an acoustic fleece that prevents fibre release, so the surface stays dust-free, anti-static and wipe-clean. It is the panel to use when a cleanroom or technical space is too noisy — a sound-absorbing complement to the solid-faced rock wool panel used for the airtight, sound-blocking shell.
Part of Wonclean's cleanroom sandwich panel family, it integrates with matching ceiling systems and cleanroom wall systems for full noise control without losing cleanliness.

It absorbs noise. The perforated face lets sound into the rock wool core where the energy is dissipated, lowering reverberation and noise level inside the room. To block sound between rooms you need a solid, sealed wall — pair this with the airtight rock wool panel as the enclosing shell.
No. The perforated face is backed with an acoustic fleece that lets sound through but keeps the mineral fibres contained, so the surface stays dust-free and anti-static. This is what makes a perforated absorber suitable for controlled environments.
Depending on thickness, core density and open area, the panel reaches an NRC / αw of about 0.85–0.95 (Class A absorber). Send us the room size and noise issue and we will recommend the perforation pattern and thickness, with the absorption curve.
The rock wool core is A-grade non-combustible and also provides thermal insulation, so one board handles acoustics, fire safety and heat control. Third-party reports to ISO 354 (absorption), EN 13501-1 (fire), ISO 9001 and CE are available on request.
Yes. Hole diameter, spacing and open area can be tuned to the target absorption, and the facing is available in RAL or custom colors. One-side perforated with a solid back is standard; double-sided perforation is available where needed.
Sample/small orders typically ship in 10–15 days and a full container in about 20–25 days from Shanghai. Perforation, color, thickness and certificates are made to order — send your panel schedule and we will confirm exact MOQ, lead time and FOB/CIF/DDP pricing.
Send us your noise problem, target absorption, thickness, color and area. Our engineers return a perforation spec, absorption curve, test reports and a factory-direct quotation — typically within 24 hours.
