Noise disturbance has become one of the most common complaints in modern urban residential areas. Traffic noise from nearby roads, talking sound from next door neighbors, children playing sound from the corridor and even television sound from the upstairs can easily penetrate ordinary thin partition walls and destroy the quiet indoor environment. EPS Cement Sandwich Wall Panel provides a highly effective and affordable solution to these annoying noise problems with its professional acoustic design.

The unique layered structure of EPS Cement Sandwich Wall Panel combines two dense cement surface layers and a porous EPS core layer, forming a gradient noise reduction system. When sound waves hit the wall, the first cement layer will reflect most of the high-frequency noise such as car horn and people's loud talking. The remaining sound energy will enter the porous EPS core, where countless tiny closed cells will continuously absorb and consume the sound vibration. Finally, the second cement layer will block the remaining low-frequency noise that tries to pass through.

Actual acoustic laboratory test shows that a 120mm thick EPS Cement Sandwich Wall Panel can achieve a sound reduction index of 48dB. This means that even if the people next door are talking at normal volume, the sound can not be heard clearly in your room. The noise from a busy main road 50 meters away can be reduced to a very faint background sound level that will not affect rest and work at all.

Many old community renovation projects have adopted this wall panel to replace the original thin and poor sound insulation partition walls. After the renovation, the number of noise complaints between neighbors dropped by more than 90%. Residents can enjoy watching movies at home, playing musical instruments or working from home without worrying about disturbing others or being disturbed by outside noise. This greatly improves the overall living happiness of the whole community.
