Building in coastal environments presents unique challenges including high humidity, constant salt air exposure, and strong seasonal wind loads, and the EPS Cement Sandwich Panel is well equipped to handle these demanding conditions when specified and installed correctly. The non metallic cement facings of the EPS Cement Sandwich Panel do not rust or corrode when exposed to salty coastal air, unlike metal siding and metal wall panels that will start to show unsightly rust stains and structural degradation after just a few years of coastal exposure. The closed cell EPS foam core inside the panel does not absorb salt water or hold moisture, which prevents the kind of hidden water damage that can rot out traditional wood frame walls in coastal locations. To maximize performance in coastal areas, it is important to select a high quality exterior paint finish that is specifically formulated to resist UV damage and salt spray erosion, and to pay extra attention to fully sealing every panel joint and fastener penetration point with a marine grade weatherproof sealant. When these simple extra steps are followed, the EPS Cement Sandwich Panel will deliver many decades of reliable, low maintenance performance in even the harshest coastal construction environments.
