Rock Wool Sandwich Panel - A1 Fire-Rated Cleanroom Panel

The rock wool sandwich panel is the industry-standard wall and ceiling system for cleanrooms with strict fire codes. A high-density mineral wool core is bonded between galvanized, stainless, or coated steel facings, delivering non-combustible performance with excellent thermal and acoustic insulation.

As a professional cleanroom panel manufacturer, we produce rock wool panels in thicknesses of 50, 75, and 100 mm with male–female (cam-lock or tongue-and-groove) joints for fast, airtight installation.
