Florida Climate Considerations

Brevard County is not in the High Velocity Hurricane Zone (HVHZ) that requires Miami-Dade ratings. Standard Florida Building Code rated impact windows meet all local permit requirements.

Brevard County's combination of 80+ percent summer humidity, intense UV exposure, salt air from the Atlantic, and seasonal storm activity creates conditions that stress building materials differently than most other markets. Homeowners in Melbourne, Viera, Cocoa Beach, Palm Bay, and the beachside communities should factor these environmental conditions into every product decision.
