Noise pollution has become one of the biggest issues that reduce the quality of life in modern urban environments and EPS Cement Sandwich Wall Panel provides a highly effective solution to create peaceful quiet indoor spaces. The special mass spring mass composite structure of EPS Cement Sandwich Wall Panel uses two dense high mass cement layers separated by the soft flexible EPS core to break the sound transmission path very efficiently. This unique structure avoids the common coincidence effect problem that plagues single layer solid walls which usually causes sudden drops in sound insulation performance at certain specific sound frequencies. Standard 125mm thick EPS Cement Sandwich Wall Panel can easily achieve a weighted sound reduction index of 48 decibels which is better than the acoustic performance of a 120mm thick solid brick wall. For buildings located near busy roads railway lines or airports you can choose the thicker 150mm version of EPS Cement Sandwich Wall Panel that delivers sound insulation performance above 53 decibels to block almost all outside traffic noise. Many residential projects located in busy city centers have reported that after switching to EPS Cement Sandwich Wall Panel the indoor noise level during peak traffic hours drops down to below 35 decibels which is quiet enough for comfortable sleeping and focused work.
