Rock wool panel
Updated: Apr 28
Rock wool sandwich panel is made from rock wool with significant effects in fire prevention, thermal insulation, sound absorption, and other aspects.
The disadvantage of rock wool sandwich panels is that their strength is not strong enough, but they are suitable for the roofs, walls, and suspended ceilings and partitions of steel structure workshops, simple activity rooms, and air clean rooms.
The colored steel rock wool sandwich panel and its production process have achieved the goal of combining rock wool and steel plate into a whole through automated equipment in the factory, thereby changing the previous way in which rock wool panels need to be composite on construction site. On the premise of meeting the requirements for thermal insulation, sound insulation, and fire prevention of buildings, the goal of high-quality, efficient, reliable, and safe has been achieved. This product has been widely used in Europe and has matured.
1. Excellent fireproof performance: The raw materials, production process, and formula used for the rock wool sandwich panel make it have excellent fireproof performance. Tests have shown that it has a fire resistance of over 1000 ° C. The rock wool sandwich panel has passed the testing conducted by the Italian authoritative testing agency GLOROANO S.P.A. 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 requirements of the fire protection standards M.I14/09/61 Letter 91 and D.M.30/11/83. The test results are as follows: 1) 50 mm thick rock wool sandwich board RE 130, 80 mm thick rock wool sandwich board REL 60 , 100 mm thick rock wool sandwich board REL 120.
2. Good thermal insulation: The thermal insulation performance of the rock wool sandwich panel is calculated based on the thermal conductivity of rock wool=0.043 W/㎡K and the thickness of the corresponding proportion of rock wool core material.
3. Significant sound absorption and heat insulation effects:
Sound insulation: Rock wool sandwich panels have a significant reduction effect on noise transmission, especially suitable for places where designated flights pass. In addition, after the use of rock wool roof panels, the impact of rain and hail on the roof steel plates of the building caused indoor noise, which was also significantly reduced. Through testing, according to ISO 717/82 and UNI 8270/7 standards, select a density of 120 kg/m³ Sandwich board with rock wool as core material can achieve a sound insulation effect of RW=29-30 dB.
Sound absorption: Rock wool sandwich panels also have excellent attractive effects, which can absorb sound in a relatively wide frequency range. According to ISO 35/85 standard, the sound absorption performance level of rock wool sandwich board reaches DELTA LA=15.7 dB (A).
But there is a shortcoming that rock wool panel is not good strong enough.
