Buildings located close to subway lines, intercity railways or heavy industrial zones face long term continuous low frequency vibration that ordinary wall materials cannot withstand. Traditional brick walls often develop staggered cracks after a few years of constant vibration, and the slots cut for wiring will gradually loosen, leading to hidden safety hazards. The EPS Cement Sandwich Panel’s unique composite structure provides excellent anti-vibration performance, solving this long-standing problem perfectly.
The high-density EPS core inside the panel acts as a natural vibration damping layer, absorbing and dispersing the low frequency vibration energy transmitted from the building’s structure, instead of letting it accumulate and damage the wall. Long term simulation vibration tests that replicate 30 years of train passing vibration show that the EPS Cement Sandwich Panel has no structural cracks, no loose screws and no deformation after the test. The slots cut for electrical wires and water pipes stay completely intact, the filling material in the slots never cracks or falls off. Even if you install the panel in a residential building 20 meters away from a subway line, residents will not hear the low frequency rumble transmitted through the wall, and there will be no wall cracks appearing after years of use. Many new residential projects built near urban subway lines now use this panel as their standard interior wall material, completely eliminating the homeowner complaint problem of wall cracks caused by long term train vibration.
