隔声:岩棉夹芯板对噪声传递有显著的消减作用,特别适用于有指定航班通过的地方。另外,采用了岩棉屋面板后,雨水、冰雹对建筑物的屋面钢板冲击而引起室内声响,也明显减弱。通过测试,按照ISO 717/82和UNI 8270/7标准,选用密度为120kg/m³岩棉作芯材的夹芯板,隔声效果可达到RW=29-30 dB
Sound insulation: rock wool sandwich panels can significantly reduce noise transmission, especially for places with designated flights. 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.
吸音:岩棉夹芯板同时具有较好的吸引效果,它能吸收比较广频率范围内的声音。按照ISO 35/85标准,岩棉夹芯板吸音性能水准达到DELTA LA=15.7dB(A)..
