Form of the spans of rock wool sandwich panel house (Deformation controlled under L/200)

Via testing according to ISO 717/82 and UNI18270/7 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:
According to the test of the Italy authority organization Istituto Giordano S.P.A, the fireproofing margin of rock wool sandwich panel is as below: (take the wall panel as the example)
Thickness: 100mm (REI) 120 minutes
          75mm (REI) 60 minutes
          50mm (REI) 30 minutes
