Industrial production processes often generate very high levels of noise, which not only harms the physical health of workers working on site for long hours, but also may cause noise pollution disputes with surrounding residential areas. Many factories face strict local environmental protection requirements that limit the noise level transmitted outside the plant and between different internal work zones. The EPS Cement Sandwich Panel delivers excellent sound insulation performance, becoming the most cost effective solution for noise reduction in factory plants.
The multi layer composite structure of EPS Cement Sandwich Panel is scientifically designed to block different types of industrial noise. The high density double side calcium silicate boards can reflect and isolate most of the high intensity mechanical noise generated by production equipment such as stamping machines, forging equipment and cutting machines. The porous inner core filled with specially treated EPS particles can absorb the residual vibration noise and low frequency rumble that penetrates through the surface layer. A standard 100mm thick EPS Cement Sandwich Panel can achieve a sound insulation performance of over 45 decibels, which is far better than the same thickness of hollow brick or color steel partition wall.
Many machinery manufacturing factories that used EPS Cement Sandwich Panel to build independent sound insulation rooms for their high noise equipment reported that the noise level outside the sound insulation room dropped from over 95 decibels to below 65 decibels after the renovation. This level of noise is low enough for workers in adjacent zones to communicate normally without wearing heavy noise protection equipment. This improvement not only greatly protects the hearing health of workers, but also helps factories meet the local occupational health and safety regulations, avoiding potential fines and labor disputes.
For factories that are located close to residential areas, using EPS Cement Sandwich Panel as the exterior wall or internal partition wall can effectively reduce the total noise level transmitted outside the plant. This helps factories easily pass the local environmental protection noise detection, avoiding the risk of being ordered to suspend production due to excessive noise complaints. Many factory managers said that after installing these panels, they no longer need to worry about being reported by surrounding residents, and their production can run continuously and stably according to the schedule. The panel also has strong impact resistance and will not be easily damaged by flying metal debris or equipment vibration in the production environment, maintaining its sound insulation performance stably for decades.
