The raw material of outer wall rock wool sandwich panel is natural volcanic rock, which is non-flammable building material and fireproof material.

Main fire protection characteristics of rock wool sandwich panel:
It has the highest fire protection level A1, which can effectively prevent the fire spreading.
The size is very stable and will not stretch, shrink or deform in the fire.
High temperature resistance, melting point higher than 1000 ℃.
No smoke or combustion droplets / debris will be generated in the fire.
Substances and gases harmful to the environment will not be released in the fire.

Applications:
Rock wool insulated panels are factory-assembled with a fire resistant mineral fiber core bonded with metal facings, suitable for fire rated wall applications, such as: wall insulation, roof insulation, door insulation and floor insulation,wall insulation is its main usage.
In certain light duty structures, unique hidden fastener details may be available depending on spans, structural loads and climatic conditions.
