Rock wool sandwich full play to the unique properties of rock wool core material in fire protection, thermal insulation, acoustic insulation and other aspects have a significant effect. Fire performance: rock wool sandwich panel roof fire rock wool board raw materials, production processes and formulations, it has good fire resistance. Tests showed that new fire rock wool board, it has over 1000 ° C fire resistance. Rock wool sandwich has passed GLOROANO SPA Italy authoritative testing organizations 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 91 No. letter and DM30 / 11/83 requirements. Test results were as follows: 1) 50mm thick rock wool sandwich RE130 80mm thick rock wool sandwich REL60 100mm thick rock wool insulation sandwich REL 120: Rock wool sandwich for noise abatement deliver significant role, especially for in a place designated by the flight. After the addition of fire rock wool board, rock wool using a roof, rain, hail on the roof of the building steel interior noise caused by the impact, but also significantly reduced. Through testing, according to UNI 8270/7 and ISO 717/82 standards, the choice of a density of 120kg / m & sup3; sandwich core material for rock wool, sound insulation effect can be achieved RW = 29-30 dB
