Complete guide to coastal and oceanfront window requirements, salt spray resistance standards, and HVHZ compliance for Palm Beach County beachfront and waterfront properties.
Side-by-side specifications for FBC-compliant coastal windows in Palm Beach County.
Basic protection
Enhanced protection
Maximum protection
Coastal windows in Palm Beach County must meet HVHZ wind load requirements (+/-60 to +/-90 PSF), impact rating per ASTM E1996, corrosion resistance for salt spray exposure, and enhanced water infiltration resistance. All glazing within the Wind-Borne Debris Region requires impact certification.
Marine-grade finishes are recommended within 1,500 feet of the ocean and required by many manufacturers for warranty coverage within 1,000 feet. Salt spray can travel several miles inland during storms, so premium finishes benefit properties up to 3 miles from the coast.
Standard coastal windows use basic impact glass and standard finishes suited for inland areas. Marine-grade windows feature enhanced corrosion protection with AAMA 2605 finishes and improved seals. Premium oceanfront systems add heavy-duty frames, triple-laminated glass, and lifetime corrosion warranties.
Standard coastal impact windows cost $55-80 per square foot installed. Marine-grade systems range from $75-110/SF. Premium oceanfront systems cost $100-160/SF. A typical beachfront home window package runs $40,000-$100,000 depending on size and specifications required.
