HardieTrim® Boards

What Are Hardie® Trim Boards?

Durable Trim for a Beautiful, Low-Maintenance Finish

Hardie® Trim Boards are made from fiber cement, a strong, weather-resistant material engineered to outlast wood and other traditional options. Each board comes primed and ready for paint, giving homeowners the flexibility to customize their exterior color palette.

These trim boards are the ideal complement to Hardie® siding but are also a great upgrade for homes using other siding materials.

Key Features of Hardie® Trim Boards

Built for Strength, Style, and Long-Term Performance

• Moisture and Rot Resistance
  Hardie® Trim Boards are specially engineered to resist water absorption. Unlike wood, they won’t swell, warp, crack, or rot when exposed to moisture—making them ideal for humid climates or areas with frequent rain and snow.

• Non-Combustible
  Made from fiber cement, Hardie® Trim is fire-resistant and will not ignite when exposed to direct flame. This adds an extra layer of safety and makes it a smart choice for homes in wildfire-prone regions or those looking for fire-rated materials.

• Pest Resistant
  The dense composition of fiber cement makes it virtually impenetrable to termites, carpenter ants, and other wood-destroying insects. You won’t have to worry about pests compromising your home’s structure or finish.

• Primed and Ready for Paint
  Each trim board comes pre-primed with a high-quality sealer that promotes strong paint adhesion. This means your chosen paint color will go on smoothly, last longer, and require fewer touch-ups over the years.

• Long-Lasting Curb Appeal
  Hardie® Trim holds its shape and appearance far better than traditional wood. It resists shrinking and expanding due to temperature changes, helping your exterior maintain clean lines and a finished look for decades.

• Versatile Applications
  Suitable for use around windows, doors, corners, columns, and fascia, Hardie® Trim adds architectural detail and definition to any home style—from traditional to modern.

• 15-Year Limited Warranty
  Backed by a James Hardie 15-year limited warranty, these trim boards are a long-term investment that delivers peace of mind and proven performance.
