One of the most destructive hidden problems in modern building walls is unseen condensation that accumulates inside the wall cavity, slowly rotting materials, feeding mold growth and destroying structural integrity over time. Most people do not realize that even walls that stop liquid rain penetration can still allow warm moist indoor air to condense inside the wall assembly, creating hidden moisture damage that is almost impossible to detect until it is already very severe. EPS Cement Sandwich Panel eliminates this problem completely with its unique monolithic structure.
Unlike traditional framed wall systems that have empty air cavities between separate layers of sheathing and insulation, EPS Cement Sandwich Panel has zero empty air gaps anywhere inside its structure. The entire space between the two cement facings is 100 percent filled with solid closed cell EPS foam, so there is literally no empty space for water vapor to accumulate and condense. The closed cell structure of the EPS material is also completely non-absorbent, so even if any tiny amount of moisture somehow found its way into the panel, the foam would not absorb or hold that moisture.
This characteristic has major long term health benefits for building occupants. Because there is no hidden moisture trapped inside the walls, there is no possible environment for toxic black mold to grow behind wall surfaces. Independent indoor air quality testing of buildings that have used EPS Cement Sandwich Panel for more than 10 years has consistently found zero traces of hidden mold growth inside the wall assemblies, even in regions with extremely high humidity. This eliminates one of the most common causes of poor indoor air quality and chronic respiratory issues in modern residential and commercial buildings.
