In tropical rainforest climate zones where the annual average relative humidity is higher than 90% and it rains almost every day, mold growth on walls is a very common problem that troubles local residents. Ordinary wall materials will be covered with thick black mold in just 2-3 years, which not only ruins the wall decoration, but also causes respiratory health problems for people living inside. The EPS Cement Sandwich Panel has passed strict long term mold resistance tests, showing excellent performance even in this extreme humid environment.
The inorganic cement material that makes up the panel surface provides no organic nutrient source for mold to grow. Even if the panel surface stays damp for a long time, mold spores cannot get the nutrients they need to reproduce. After 6 months of continuous mold culture test in the lab, the mold growth coverage rate on the EPS Cement Sandwich Panel surface is 0%, far exceeding the highest mold resistance standard. The slots cut for wiring and plumbing, after being filled with cement-based filler, also show zero mold growth. Unlike gypsum walls and wood walls that are quickly covered with mold in tropical areas, this panel can stay completely mold-free for more than 20 years. Local residents can wipe the wall surface easily to remove any accidental water stains, and the wall will never produce any musty smell. Many local residential and public building projects in tropical rainforest regions have adopted this panel, completely solving the long standing wall mold problem that has bothered local people for generations.
