How to choose rock wool wall panel as thickness?

Project Reference

This 3,800 m² electronics workshop in Mexico adopted our 75 mm rock wool wall panels. It achieves 30 dB sound insulation with 60% shorter construction time. Installation finished in only 12 days, and panels passed fire inspection at the first trial. Compared with traditional walls, the system ensures reliable fire & acoustic performance and cuts total cost by 28%.
