The core technical highlight lies in the high-density porous structure design. A large number of porous mineral fibers are added inside the board to form a multi-layer sound insulation barrier, which can effectively block air sound transmission above 45dB, and the sound insulation performance is increased by more than 30% compared with ordinary calcium silicate boards. At the same time, the board density is as high as 1300kg/m³, which has excellent impact resistance and can effectively block solid sound transmission, solving the problem of noise interference between upstairs and downstairs. In addition, the product has A1 fire rating and reaches E0 environmental protection grade, and will not release toxic and harmful substances. It is suitable for all kinds of sound insulation partitions and ceiling scenarios, providing long-term sound insulation and fire protection guarantee for the space.
The standard size is 1220mm×2440mm, with three thickness specifications of 12mm, 15mm and 20mm available. The board density is stable at 1300kg/m³, the bending strength is ≥16MPa, the impact strength is ≥4.0kJ/m², the thermal conductivity is 0.021W/(m·K), the sound insulation rating reaches ASTM E90 45dB standard, the water absorption is ≤7%, the environmental protection grade is E0, the formaldehyde emission is ≤0.05mg/m³, the surface is flat and smooth, and it is suitable for light steel keel installation system, and can be used with sound insulation cotton to further improve the sound insulation effect.
It is mainly used for sound insulation partitions and sound insulation ceilings of cinemas, KTVs, recording studios, school classrooms, hospital wards, office offices and other places that require quiet environment, as well as sound insulation walls for bedrooms and study rooms in family homes. This product has both sound insulation and fire resistance performance, complies with national building sound insulation and fire protection standards, and provides a quiet and safe environment for the space, reducing noise interference and improving the space use experience.
