Sandwich board Rock Wool Plate is with the prominent performance for reducing the noise, especially suitable for the area of low noise requirement. And using rook wood plate construction will reduce the sound from raining and hail hitting the building. After testing, based on ISO717/82 and UNI18270/7 standard, using density of 100KG/m3 and thickness of 50-100mm rock wood plate effect of Soundproof can be RW=29-30db.
Sandwich board And rock wood core material is non-flammable materials, with the fire resistance rate of 1000 degree. According the testing result of Italy Istitutogiodano S.P.A testing, rock wool core fire endurance is as below:
100mm thickness (REI): 120min
75mm thickness (REI): 60min
50mm thickness (REI): 30min
