Product Advantages
Silica Rock Sandwich Panel provides outstanding fire safety, thanks to its Class A non-combustible core. The core remains stable even at temperatures as high as 1500°C, without melting or releasing toxic smoke. Its thermal conductivity is remarkably low-just 0.035 W/(m·K)-which ensures excellent insulation performance. Unlike traditional rockwool panels, the silica rock core absorbs very little water, giving it superior moisture resistance. The surface is smooth, generating no dust or static electricity, so cleaning becomes effortless. Because the panel is lightweight and easy to cut, construction time and labor costs are significantly reduced.
Main Applications
You will find Silica Rock Sandwich Panel used in a variety of demanding environments. Pharmaceutical factories, food processing workshops, and electronic clean rooms all rely on it for its clean and fire-safe properties. Medical operating rooms and laboratories also benefit from its smooth, dust-free surface. Beyond clean spaces, the panel works well for steel structure workshops, logistics warehouses, and public buildings where fire resistance and insulation matter. Wherever strict cleanliness and safety are required, Silica Rock Sandwich Panel delivers reliable performance.
FAQ
Q1: What is the fire rating of Silica Rock Sandwich Panel?
A1: The panel reaches Class A (non-combustible). The core does not melt or release toxic smoke even at 1500°C, making it a safe choice for fire-sensitive projects.
Q2: How do I choose the right thickness?
A2: For clean room ceilings and partitions, 50–75mm works well. For wall panels, 75–100mm is common. When higher insulation is needed, such as in cold storage or extreme climates, choose 100mm or more.
