Core sandwich panel of mineral wool is applicable for the project of high request firing prevention. Mineral wool perpendicular to metal panel, high density strip mineral-wool assign along the panel interleaving, which guarantee core sandwich panel of mineral wool has good bearing capacity. Result of insulating against sound is remarkable. Mineral-wool Core sandwich panel have remarkable effect in cutting down the transmittal of noise. This function is very suitable for the place of high request of sound insulation. In addition, after adopting the mineral-wool roof panel, the indoor sound caused by the rainwater and hail assaulting the building roof panel, will be obviously weaken too. Through tests, according to ISO717/82 and UNI18270/7 standard , the result of sound insulation can reach RW=29-30dB while choosing 50-100mm thick splint which is cored by mineral-wool whose density is 100kg/one cubic meter. Excellent performance in fireproofing. The mineral-wool core is not the alkene burns materials. It has the fire-resistant ability with over 1000 degrees Centigrade. Determine according to Italy authoritative organization Istituto Giordano S.P.A, the panel and wallboard’s limit of fire-resistant is 120 minutes for 100mm thick (REL), 60 minutes for 75mm thick(REL), 30 minutes for 50mm thick(REL). The fire-resistant grade for 50-70-100mm thick panel is 0/1 grade (Its fire-resistant grade is divided into 0 , 1 , 2 , 3 , 4 , 5 grades sequentially from high to low)
