Homes built near the ocean face a unique harsh challenge: salty sea air that corrodes metal, rots wood, and damages traditional wall materials very quickly. A normal drywall or wood frame wall in a coastal area will start to show serious corrosion and damage within 10 years. EPS Cement Sandwich Wall Panel is almost completely immune to salt air corrosion, making it the perfect wall material for seaside homes.

The outer cement layer of a high-quality EPS Cement Sandwich Wall Panel is specially formulated to resist salt erosion. Independent 5-year salt spray tests show that the surface of EPS Cement Sandwich Wall Panel shows zero signs of corrosion or degradation, while regular cement boards develop deep cracks and salt deposits after 2 years of the same test. This means an EPS Cement Sandwich Wall Panel coastal home can easily last 30+ years without any major wall repair work.

Unlike metal siding that rusts quickly in salty air, EPS Cement Sandwich Wall Panel contains no metal parts that can corrode. Even the screws used to install the EPS Cement Sandwich Wall Panel can be replaced with stainless steel screws for extra coastal corrosion protection. Thousands of homeowners in Florida and Southeast Asia have chosen EPS Cement Sandwich Wall Panel to build their seaside homes, and they almost never need to do frequent wall maintenance work.
