Product Introduction
Rockwool Sandwich Wall Roof Panel
This panel uses two corrosion resistant steel sheets as outer layers. The core is high density rockwool. This structure delivers A2 fireproof protection, excellent thermal insulation, and strong sound absorption. The steel faces provide mechanical strength and impact resistance. It works perfectly for industrial walls, warehouse roofs, and prefab buildings. The rockwool core does not burn or release toxic smoke. This panel keeps your building safe, warm, and quiet.
