Insulation in Florida: What You Need to Know
Florida falls in Climate Zone 2A (Hot-Humid), which keep heat out and manage moisture carefully. Understanding these local factors helps you make better decisions about materials and timing.
Attic Priority
Radiant barrier + adequate insulation. Hot attics (150°F+) radiate heat into living space.
Vapor Control
Vapor barriers go on exterior (opposite of cold climates). Wrong placement causes mold.
Code Requirements
R-38 attic, R-13 walls typical code minimum. Spray foam air sealing adds significant value.
