Rock wool sandwich panel is a sandwich board made of rock wool. Rock wool sandwich panels give full play to the unique properties of rock wool core materials, in fire prevention, thermal insulation, sound insulation and other aspects have a significant effect.
The disadvantage of rock wool sandwich panel is that its strength is not strong enough, but it is suitable for steel structure workshop, roof of simple movable room, wall, ceiling and partition of air cleaning room, etc. Advantage
Rock wool sandwich panels give full play to the unique properties of rock wool core materials, in fire prevention, thermal insulation, sound insulation and other aspects have a significant effect.
1. Excellent fire-proof performance: Rock wool sandwich board used raw materials, production technology and formula, so that it has a good fire-proof performance. Tests show that it has a fire resistance of more than 1000 degrees C. Rock wool sandwich panels have passed the tests of GLOROANO S.P.A, an authoritative testing agency in Italy. According to the standards of ISO, BS and DIN in Germany, rock wool sandwich panels meet the requirements of fire protection standards M.I14/09/61, letters 91 and D.M.30/11/83. The results are as follows: 1) 50 mm thick rock wool sandwich board RE130 80 mm thick rock wool sandwich board REL60 100 mm thick rock wool sandwich board REL 120
2) Good thermal insulation: The thermal insulation performance of rock wool sandwich board is based on the thermal conductivity of rock wool = 0.043W / K, and calculated by the thickness of rock wool core material in the corresponding proportion.
3) sound absorption and heat insulation effect is remarkable.
Sound insulation: Rock wool sandwich panels have a significant effect on reducing noise transmission, especially suitable for places with designated flights through. In addition, the use of rock wool roof, rain, hail on the roof of the building steel plate impact caused by indoor sound, but also significantly weakened. According to ISO 717/82 and UNI 8270/7 standards, the sandwich panel with density of 120 kg/m & sup3 and rock wool as core material is selected, and the sound insulation effect can reach RW=29-30 dB.
Sound Absorption: Rock wool sandwich board also has an excellent attraction effect, it can absorb a wide range of frequencies within the sound. According to ISO 35/85 standard
The level of sound absorption of rock wool sandwich panels reaches DELTA LA=15.7dB (A).
