The internal porous clay sound-absorbing core layer has a noise reduction coefficient NRC≥0.75, which can effectively absorb medium and high frequency noise and reduce indoor reverberation time. At the same time, it retains the natural texture and texture of rammed earth materials. Compared with traditional sound-absorbing materials such as glass wool and rock wool, the appearance is more beautiful and natural, meeting the aesthetic requirements of modern spaces. The panel has Class A fire rating and E0 environmental protection standards, no odor release, and the installation method is dry hanging, without additional sound-absorbing decorative layers, simplifying the construction process.
The standard size is 1220mm×2440mm, with a thickness of 20mm. The density is 1750 kg/m³, the water absorption rate is ≤9%, the surface adopts microporous matte treatment, which has both sound absorption and anti-slip properties. Customized textures and colors are available to meet the needs of different acoustic spaces, and the service life is ≥20 years.
It is mainly used for cinema screening halls, recording studios, school classrooms, open office areas, libraries, hotel guest rooms and other indoor spaces requiring acoustic optimization.
