Rock wool sandwich panel is applicable to project with fairly high demand upon fire protection. The rock wool fibres plum to color steel plates. High density strip rock wool crisscross with the length of the color steel plates. All of these guaranteed the rock wool sandwich panels have good bearing capability.
Feature :
Rock wool sandwich panel has a good feature in noise reduction, especially suitable for the place where is high requirement in the sound-insulation. Via testing accordingly to ISO 717/82 and UNII 8270/7 standards, selecting the rock wool which with the density 105 kg/m2 and the thickness 50-100mm as the core, the sound coefficient will achieve RW=29-30 dB.
Excellent fire resistance :
The ability of the fire-proofing of the rock wool sandwich panel is over 1000 ͦC for the rock wool is the non-fire material.
According to the test of the Italy authority organization Institution Giordano S.P.A the fireproofing margin of rock wool sandwich panel is as below : ( using wall panel as sample )
Thickness  : 100mm ( REI ) – 120mins
                      75mm ( REI ) – 60 mins
                      50mm ( REI ) – 30 mins
The fireproof degree of rock wool panels of 50, 75, & 100mm are 0/1 ( with their fire-proof degree from high to low is 0, 1, 2, 3, 4, 5 )
