Rock wool is non-combustible material, so the rock wool panel has good fire-resisting proper.The test shows the temperature of the panle fire-proof is as high as 10001?.The test results obtained by Istituto Giordano S.P.A is as follow:
Roof and Wall panel thickness 100 REI 120
Roof and Wall panel thickness 80 REI 60
Roof and Wall panel thickness 50 REI 30
The roof and wall panels, thickness 50-80-100mm, were classified 0/1 for reaction to fire. (Materials are assigned a class from 0 to 5, the higher the class, the higher the degree of combustion.)

Rock wool panel achieves a notable reduction in air borne sound transfer, particularly when specifying a perforated liner.The impact of rain and hail on the metal sheet, a problem on most standard constructions is greatly reduced when adopting CX-RW panels.The CX-RW panel in thicknesses of 50-100mm with 100kg/m3 rock wool fibre insulation has achieved results of RW=29-30 dB according to UNI 8270/7 and ISO 717/82.
