What to Compare
James Hardie HardiePlank (fiber cement) is the premium choice for Florida — particularly coastal and hurricane-zone homes. It's inorganic at its core (no wood fiber at the surface), resists moisture and salt air excellently, and carries Miami-Dade NOA approval. For Florida, James Hardie is worth the premium in most cases.
