Huamei Jingyi Glass Wool Sound Insulation Board
Glass wool sound insulation sheet is used for building floor, based on the increasing demand of consumers for theliving environment, Huamei Group has developed a sound insulation sheet using a special formula process, whichcan effectively reduce the transmission of noise.lt can suppress the impact noise in the whole frequency rangeeffectively isolate the impact noise and the airborne noise, and the sound insulation board has excellent propertiessuch as thermal insulation,environmental protection and flame retardancy
Product Description
1.HUAlMEl jingyi glass wool sound insulation board will be laid on the concrete floor of the building. The edges of twoneighbors boards should be attached closely,. 3-5mm gaps should be ensured between the four edges of the panel and thebuilding wall.
2.The gap between the panels should be sealed by soundproofing sealant. 3-5mm gaps should be ensured between thefour edges of the panel and the building wall and sealed by soundproofing sealant.3.To lay pea gravel concrete on the soundproofing panel, make it level, then lay decoration materials on it.
