Rock wool sandwich panels are suitable for projects with high requirements for fire prevention. Rock wool fibers are perpendicular to the metal panel, and high-density strip-shaped rock wool is arranged in a staggered manner along the length direction of the panel, ensuring that the rock wool sandwich panel has good load-bearing capacity.
Rock wool sandwich panels have a significant reduction effect on noise transmission, especially suitable for places with high requirements for sound insulation. In addition, after using rock wool roof panels, the indoor sound caused by rainwater and hail on the roof impact surface of the building is also significantly reduced. Through testing, according to ISO717/82 and UNI18270/7 standards, using a 50-100mm thick sandwich panel with a density of 105kg/M3 rock wool core material can achieve a sound insulation effect of RW=29-30dB
The rock wool core material is a non combustible material, so the rock wool sandwich panel has a fire resistance capacity of over 1000 ℃. According to the Italian authoritative institution Istituto Giordano S.P.A, the fire resistance limit of rock wool sandwich panels and wall panels is 60 minutes.
