Many architects and interior designers are very concerned about the actual sound insulation performance of Ceramsite Panel Expanded Clay Cement Panel, because this index directly affects the usage experience of the building space. The official third party acoustic performance test data can help you clearly understand the real noise reduction effect of this material. According to the national authoritative building material test center’s test report, the 90mm thick single layer standard Ceramsite Panel has a weighted sound insulation Rw value of 42dB. This means that this single layer panel can effectively isolate the normal speaking voice volume. The people in adjacent rooms can not hear the conversation clearly. If you use two layers of 90mm Ceramsite Panel with 50mm thick sound insulation cotton filled in the middle of the air gap, the weighted sound insulation Rw value can reach more than 53dB. This performance has exceeded the sound insulation effect of the 240mm thick traditional solid clay brick wall. This level of sound insulation can completely meet the highest sound insulation requirements of hotel guest rooms school classrooms office partitions and recording studios. The unique porous internal structure of expanded clay particles in the panel is the core reason for its excellent sound insulation performance. A large number of tiny independent pores inside the material can convert the sound wave energy into tiny heat energy through continuous reflection and consumption, so as to achieve very ideal sound absorption and noise reduction effect. The test data also shows that the sound insulation performance of Ceramsite Panel will not decrease with the change of service time. Even after 30 years of long term use, its sound insulation effect can still remain more than 98 percent of the initial performance. In the actual engineering test, after using the double layer Ceramsite Panel partition wall between two hotel guest rooms, the background noise interference from the adjacent room is almost completely eliminated. The guest satisfaction score for quietness increased by more than 40 percent. These real test data prove that Expanded Clay Cement Panel is not only a lightweight fast construction wall material, but also a very excellent high performance sound insulation building material.
