System Overview A Rockwool Cleanroom Panel bonds two corrosion-resistant color-steel facings to a high-density rock wool core — an A-grade fireproof, sound-insulating cleanroom wall and ceiling panel made to a ≤ 2 mm/2 m flatness tolerance. Key advantages: A-Grade Fireproof: Non-combustible mineral-wool core with up to 1–2 h fire resistance. Durable Steel Facing: Top-brand coated steel — corrosion-resistant, anti-static, no dust accumulation. Thermal & Acoustic: Dense rock wool damps noise and stabilizes temperature for HVAC.
