What Are Rockwool Sandwich Panels?
Composition and Structure
Rockwool Sandwich Panels are made of three main parts. The top and bottom layers are strong steel sheets that are pre-painted and galvanized. Between these layers is a core made of rock wool, which comes from volcanic rock. The rock wool is placed upright to give the best insulation. These panels come in different thicknesses, like 50mm to 150mm, and fixed widths of 1150mm or 950mm. They can be as long as 12 meters, making them useful for many building projects.
The panels also have special coatings, like aluminum or zinc, to make them last longer. Machines build these panels to ensure they are always high quality. This design makes them great for walls, roofs, and ceilings in factories, cold storage, and public buildings.
Part | Details |
---|---|
Outer Layers | Pre-painted galvanized steel |
Core Material | Rock wool with density of 100 or 120 kg/m³, placed upright |
Insulation Features | Stops fire, keeps heat in, and blocks noise |
Uses | Perfect for walls, roofs, and ceilings in factories and cold storage |
Options include 50mm, 75mm, 100mm, 125mm, and 150mm | |
Steel Sheet Thickness | Between 0.326mm and 0.6mm |
Panel Widths | Fixed at 1150mm or 950mm, lengths up to 12 meters |
Coating Choices | Aluminum, zinc, or color-coated steel |
Unique Properties of Rockwool Panels
Rockwool Panels are special because of their strong features. They do not burn and can handle heat up to 1000°C, making them safer than other panels. They also absorb sound well, which helps reduce noise in busy places. These panels resist water, so they last longer even in wet areas.
Unlike panels made from plastics, Rockwool Panels use natural basalt rock and recycled steel. This makes them better at stopping fires and keeping heat inside. They also block noise and resist water, making them useful for homes and factories.
Feature | Rockwool Panels | Other Panels (e.g., PUF) |
---|---|---|
Materials | Made from basalt rock and recycled steel | Often made from synthetic materials |
Fire Safety | Do not burn, handle heat up to 1000°C | Treated to resist fire, but may melt |
Sound Absorption | Excellent at reducing noise | Good, but not designed for sound absorption |
Water Resistance | Very resistant to water and moisture | Less resistant to water |
Comparison with Other Panel Types
Rockwool Panels perform better than other panels in saving energy and reducing noise. They are great at absorbing sound, which makes them perfect for noisy places. Other materials, like fiberglass, block sound but don’t absorb it as well.
Rockwool Panels also save energy by keeping heat in. Their thermal conductivity is as low as 0.043 W/mK, which lowers energy bills. They are rated highly for fire safety under the Euroclass system (A1, A2, B), meaning they don’t burn or burn very little.

Tip: Panels that are 80mm thick can resist fire for one hour. Panels that are 100mm thick can last two hours. This makes them a safe choice for buildings.
