For people living near busy roads, working in open offices, or running home music studios, noise pollution can seriously reduce quality of life, and the EPS Cement Sandwich Wall Panel delivers surprisingly excellent sound insulation performance that solves this problem effectively. Independent acoustic lab tests show that a standard 120mm thick EPS Cement Sandwich Wall Panel can achieve a sound transmission class (STC) rating of 45, which is enough to block 90% of normal street traffic noise, loud conversations, and TV sound from adjacent rooms.

If you need even higher sound insulation performance for a recording studio or hotel room, you can choose a 150mm thick EPS Cement Sandwich Wall Panel with an additional layer of sound-absorbing rock wool inside, which can push the STC rating up to 55. This level of performance means you can play music at normal volume inside the room without disturbing people in the next unit. Unlike thin plasterboard partition walls that let almost all low-frequency noise pass through, the dense fiber cement surface of the EPS Cement Sandwich Wall Panel effectively blocks deep bass sounds, creating a truly quiet indoor space.

Many hotel operators that switched to the EPS Cement Sandwich Wall Panel for guest rooms reported a 30% increase in positive guest reviews related to room quietness after renovation.
