Rock wool sandwich board is a kind of sandwich board made of rock wool.
Rock wool sandwich board gives full play to the unique performance of rock wool core material, and has remarkable effect in fire prevention, heat insulation, sound absorption and sound insulation, etc.
1. Excellent fire performance: rock wool sandwich board USES raw materials, production process and formula, so that it has a good fire performance.
Tests show that it has a fire resistance of more than 1000°C.
Rock wool sandwich panels have been tested by GLOROANO S.P.A., an Italian testing authority. In accordance with the standards of the International Organization for Standardization (ISO), BS of the United Kingdom and DIN of Germany, the rock wool sandwich panels meet the requirements of fire protection standards M.I. 14/09/61 Letter 91 and D.M.30/11/83.
The test results are as follows: 1) 50mm thick rock wool sandwich board RE130 80mm thick rock wool sandwich board REL60 100mm thick rock wool sandwich board REL 120.
2. Good thermal insulation: the thermal insulation performance of rock wool sandwich board is calculated based on the thermal conductivity of rock wool = 0.043w /㎡K, and the corresponding thickness of rock wool core material is calculated.
3. Significant sound-absorbing and heat-insulating effect: sound insulation: Rock wool sandwich panel has a significant reduction effect on noise transmission, especially in places with designated flights.
In addition, after the use of rock wool roof board, rain, hail on the building roof steel plate impact caused by indoor sound, also significantly weakened.
The density was 120kg/ M&SUp 3 according to ISO 717/82 and UNI 8270/7.
With rock wool as the core material, the sound insulation effect can reach RW= 29-30dB
Sound absorption: Rock wool sandwich board also has excellent absorption effect, it can absorb sound over a wide frequency range.
In accordance with ISO 35/85
, sound absorption performance of rock wool sandwich board reaches DELTA LA=15.7dB(A)..
