Characteristics of rock wool sandwich board
Rock wool sandwich board fully exerts the unique properties of rock wool core material, and has remarkable effect in fire protection, insulation and sound insulation, sound absorption and sound insulation.
● excellent fire resistance: raw material, production technology and formula used for rock wool sandwich board, so that it has good fireproof performance. The test shows that it has more than 1000 degree of C fire resistance. Rock wool sandwich panels have been tested by GLOROANO S.P.A, an authoritative inspection institution in Italy. According to the standards of International Standardization Organization (ISO), British BS and German DIN, the rock wool sandwich panels meet the requirements of fire protection standards, M.I14/09/61 91 and D.M.30/11/83. The experimental results are as follows: 1) 50mm thick rock wool sandwich board RE130 80mm thick rock wool sandwich board REL60 100mm thick rock sandwich board REL 120
● good thermal insulation: insulation rockwool sandwich panel is =0.043W/ square meters of K thermal conductivity of rock wool according to the corresponding proportion of the cotton core material thickness calculation.
● the effect of sound absorption and heat insulation is remarkable.
Sound insulation: rock wool sandwich panels have a significant reduction in noise transmission, especially for places where a designated flight is passed. In addition, after using the roof of the rock wool roof, the rain and hail impact on the roof plate of the building, causing the sound of the indoor sound and also obviously weakened. Through the test, according to ISO 717/82 and UNI 8270/7 standard, select the density of 120kg/m³ the core plate of rock wool as core material, the sound insulation effect can reach RW=29-30 dB
Sound absorption: rock wool sandwich panels have excellent attraction at the same time, which can absorb sound in a wide range of frequencies. According to the ISO 35/85 standard
The sound absorption performance level of the rock wool sandwich panel reaches DELTA LA=15.7dB (A)..
The strength is not good enough.
