The combination of mineral wool or rock wool fibers contains a large amount of free air space, and even if it is compressed by rolls or sheets,it has excellent sound insulation properties.

Rockwool panels Sound damping value

Core material thickness(mm)

Sound reduction index(dB)

Spectrum adaptation factors



















Note:These data is based on steel thickness 0.40-0.50mm and rock wool density 100KG/M³.

C) Insulation performance:

Rock wool products have thermal conductivity with K value between 0.03-0.04 W/m·K,which ensure they could be available in high temperature industrial buildings.

6. Sandwich panel storage:

10 rockwool-sandwich-panel-stacking 

A, The stacking location must be flat, strong, clean, and ventilated. The yard should be as close as possible to the area where the siding is installed to avoid long-distance secondary transportation.

B,When stacking, please pay attention to adjust the height with the sleepers, and make wall sandwich panel has a tilt angle of 2"'50C after stacking,so that even if water flows between the external steel composite panels,the water will not stay on wall/roof panel.If wall/roof panels are placed outdoors, it must be covered by tarpaulin. And it must be completely covered,especially when core material is rock wool or grass wool,the exposed part should be strengthened to avoid damage to the core material due to rain.

C,Wall sandwich panels stacking should be kept away from other exposed steel materials,in order to prevent the rust on these steel materials from falling and adhering to the outer wall sandwich panels. It is difficult to remove,and will cause rust spots and penetrate into the steel sheet.

D,When wall panels are stacked one on another, please dont place more than two piles per stack. Heavy objects and pedals cannot be placed on wall sandwich panels to avoid damage to the top coating or even the steel sheet.

E,The sandwich wall panel is wrapped with a polyethylene protective film. The film cannot be exposed to direct sunlight for a long time, otherwise the protective film will be difficult to tear off.

F,Regarding flashings,they must also be stacked neatly. If it is placed outdoors, it must be completely covered with a tarpaulin.

7. Insulated panel carrying at site:


Protective gloves and goggles must be used throughout the manual handling. For the handling of a single façade, the length of the slab should be lifted by 3" '5 people, so as not to deform the siding. To prevent the interface from being damaged, the flat can not be picked up at the interface. When transporting, do not drag wall panels on the surface of the object, and do not drag wall sandwich panels to each other to avoid damage to the topcoat. Avoid bending when handling. Bending will rupture the core of the panel and permanently deform the inner and outer surfaces.
