Double-sided PVDF galvalume and marine aluminum standing seam roof sheets engineered for oceanfront salt spray, with optional 100% PFAS-free formulations for rainwater harvesting.
“Standard galvanized metal roofs in Guanacaste begin rusting at the screw holes within 3-4 years. We specify Marine Kynar 500 with concealed clips because it lasts 30+ years right on the Pacific high-tide line.”
Double-sided 70% fluoropolymer Kynar 500 PVDF resin coating will not chalk, peel, or rust under Pacific salt air spray.
Zero exposed penetration screws. Thermal expansion clips allow movement without tearing or leaks.
Mechanically seamed interlocking ribs tested to withstand extreme tropical storm wind shear.
Infrared reflective pigments keep attic cavities up to 18°C cooler during blistering dry season sun.
