1. Excellent fire resistance: The raw materials, production technology and formula used in the rock wool sandwich panel make it have good fire resistance. Tests show that it has a fire resistance over 1000°C. The rock wool sandwich panel has passed the test of the authoritative Italian testing organization GLOROANO SPA. According to the standards of the International Organization for Standardization (ISO), the British BS and the German DIN, the rock wool sandwich panel meets the fire protection standard M.I14/09/61 letter 91 And the requirements of DM30/11/83. The 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) Good thermal insulation: The thermal insulation performance of the rock wool sandwich panel is calculated based on the thermal conductivity of the rock wool=0.043W/㎡K and the thickness of the rock wool core material in the corresponding proportion.
3) The effect of sound absorption and heat insulation is remarkable:
Sound insulation: Rock wool sandwich panels can significantly reduce noise transmission, especially suitable for places where designated flights pass. In addition, after the use of rock wool roof panels, rain and hail impact on the roof steel plates of the building and cause indoor noise, which is also significantly weakened. Through the test, in accordance with ISO 717/82 and UNI 8270/7 standards, a sandwich panel with a density of 120kg/m³ rock wool as the core material is selected, and the sound insulation effect can reach RW=29-30 dB
Sound absorption: The rock wool sandwich panel also has an excellent attracting effect, and it can absorb sound in a relatively wide frequency range.
