Rock wool sandwich panels give full play to the unique properties of rock wool core materials, and have significant effects in fire prevention, thermal insulation, sound absorption and sound insulation.
1, excellent fire performance: rock wool sandwich panels using raw materials, production processes and formula, so that it has a good fire performance. Tests have shown that it has a fire resistance of more than 1000°C. Rock wool sandwich panels have passed the test of Italian authoritative testing agency GLOROANOS.PA. According to the standards of the International Organization for Standardization (ISO), British BS, and German DIN, rock wool sandwich panels meet the fire protection standard M.I14/09/61 letter 91 No. and DM30/11/83 requirements. The test results are as follows: 1) 50mm thick rockwool sandwich panel RE13080mm thick rock wool sandwich panel REL60100mm thick rock wool sandwich panel REL120
2) Good thermal insulation: The thermal insulation performance of the rockwool sandwich panel is based on the thermal conductivity of rock wool = 0.043W/m2K, and is obtained by calculating the thickness of the rockwool core material correspondingly.
3) Significant sound absorption and heat insulation effects:
Sound Insulation: Rock wool sandwich panels have a significant reduction effect on noise transmission and are particularly suitable for use by designated flights. In addition, after adopting the rock wool roofing panels, rain and hail impacted the roofing steel plate of the building and caused indoor sound, which was also significantly reduced.
Sound Absorption: The rockwool sandwich panel has excellent suction effect at the same time. It can absorb sound in a wide frequency range. According to ISO35/85 standard, the sound absorption performance of rockwool sandwich panel reaches DELTALA=15.7dB(A)
