Feature:Rock wool sandwich panel has a good feature in noise reduction,specially suitable for the place where is high requirment in the sound-insulation.Via testing according to ISO 717/82 and UNI 18270/7 standards,selecting the rock wool which with the density 105kg/m3 and the thickness 50-100mm as the core,the sound coefficient will achieve RW=29-30dB
Excellent fire resistance:The ability of the fire-proofing of the rock wool sandwich panel is over 1000℃ for the rock wool is the non-fire material.According to the test of the Italy  authority organization Istituto Giordano S.P.A,the fireproofing margin of rock wool sandwich panel is as bellow:(take the wall panel as the example)
Thickness:100mm(REI)120 mins
                 75mm(REI)60 minutes
                 50mm(REI)30 minutes
The fireproof degree of rock wool panels of 50-75-100mm are 0/1(with their fire-proofdegrees from high to low is 0,1,2,3,4,5)
