Rock wool sandwich full play to the unique properties of mineral wool core material in fire protection, thermal insulation, acoustic insulation and other aspects have a significant effect. 1, fire performance: rock wool sandwich panel used in raw materials, production processes and formulas, it has good fire resistance. Tests showed that it has more than 1000 ° C fire resistance. Rock wool sandwich panel has passed the Italian authoritative testing organizations GLOROANO SPA test, according to the International Organization for Standardization (ISO), the British BS and German DIN standards, rock wool sandwich panels meet fire safety standards M.I14/09/61 Letter No. 91 and DM30/11/83 requirements. Test results are as follows: 1) 50mm thick rock wool sandwich panel RE130 80mm thick rock wool sandwich panel REL60 100mm thick rock wool sandwich panel REL 120 2) insulation resistance: rock wool sandwich panel insulation properties are with rock wool thermal conductivity = 0.043W / m K as the basis, the corresponding proportion of mineral wool core material thickness calculation obtained. 3) acoustic insulation effect is remarkable: insulation: rock wool sandwich panel for noise abatement passed a significant role, especially for a designated route through the place. In addition, the use of rock wool roof after the rain, hail impact on the building roof plate caused by indoor sound, but also significantly reduced. Tested in accordance with ISO 717/82 and UNI 8270/7 standard, the choice of a density of 120kg / m? Wool as core material for sandwich panel, sound insulation effect can be achieved RW = 29-30 dB acoustic: rock wool sandwich panel also has excellent suction effect, can absorb relatively wide frequency range sound. In accordance with ISO 35/85 standard, rock wool sandwich panel acoustic performance level reached DELTA LA = 15.7dB (A) ..
