Hidden condensation inside wall cavities is a very dangerous problem that many building owners do not notice until it causes serious structural damage, mold growth and rotten internal structures. Traditional multi-layer wall systems often trap moisture inside the cavity, which cannot escape, leading to long term hidden problems that are extremely expensive to repair. The monolithic composite structure of EPS Cement Sandwich Panel completely eliminates this hidden condensation risk.
Unlike traditional walls that are assembled from multiple separate layers, the EPS Cement Sandwich Panel is manufactured as one unified piece. The cement facing layer and the inner EPS core are bonded together under high pressure in the factory, with zero tiny gaps between different layers. There is no empty cavity inside the panel for moist air to circulate and accumulate. When you cut slots on the panel for wiring and pipes, after you fill the slots completely with cement-based filler, the repaired area also forms a solid continuous structure with no hidden gaps. The panel’s vapor permeability is carefully calibrated to allow small amount of water vapor to pass through slowly, without trapping any moisture inside. Actual long term monitoring data shows that after 10 years of use, there is zero moisture accumulation inside the EPS Cement Sandwich Panel, even in high humidity tropical coastal regions. This completely eliminates the hidden condensation problem that plagues many traditional wall systems, removing a major hidden danger that can reduce a building’s service life by decades.
