Hardie Board vs. Vinyl Siding: Florida Homeowner Guide

A&E Remodeling has been protecting Tampa Bay homes since 1995, and one of the most common questions our St. Petersburg siding experts hear is: “What’s the difference between Hardie board and vinyl siding?” This comprehensive guide will help Florida homeowners understand which type of siding to use for our unique climate challenges.

The Florida Siding Challenge

Florida’s climate creates exceptional demands on your home’s siding. From scorching UV exposure and high humidity to high winds during hurricane season and salt air corrosion near coastal areas, your siding choice directly impacts both your home’s protection and your long-term maintenance costs.

Many homeowners initially focus only on upfront costs, but in Florida’s harsh environment, the true value of your siding investment must consider:

• Long-term durability in extreme weather conditions
• Resistance to moisture and humidity damage
• Hurricane performance and wind ratings
• Maintenance requirements in our climate
• Energy efficiency in our hot environment
• Overall lifetime value and ROI

Let’s examine how James Hardie fiber cement siding (commonly called Hardie board, HardiePlank, or Hardie siding) and vinyl siding compare across these critical factors for Florida homes.

Hardie Board vs. Vinyl: Material Composition

James Hardie Fiber Cement Composition

Hardie siding is a fiber cement product made from:

• Portland cement
• Cellulose fibers (wood pulp)
• Sand
• Water
• Proprietary additives

This combination creates a remarkably stable, durable material specifically engineered for residential exteriors. James Hardie offers products from their HardieZone® System, with formulations specifically designed for Florida’s high-humidity, high-heat environment. Fiber cement siding is typically about 5/16 inches thick, making it substantially thicker than vinyl siding.

Vinyl Siding Composition

Vinyl siding is made primarily from:

• Polyvinyl chloride (PVC)
• UV stabilizers
• Impact modifiers
• Colorants

Modern vinyl siding has significantly improved from earlier generations, with better stabilizers to resist fading and improved impact resistance. However, its fundamental properties as a plastic-based product remain unchanged. Vinyl siding can be backed with foam insulation to improve its insulating properties and durability.
