System Overview 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: Absorbs Noise: Perforated face plus mineral core cuts reverberation and lowers room noise levels. Cleanroom-Safe: Acoustic fleece behind the perforations stops fibre release — dust-free and A-grade non-combustible. Insulates Too: The rock wool core adds thermal insulation in a single board.
