Fiber cement siding (also widely known as James Hardie siding) is designed to enhance the exterior of a home while recreating the appearance of traditional wood or vinyl siding.
Developed over a century ago, this type of cement siding was created to protect buildings from extreme weather conditions while maintaining long-lasting visual appeal.
Seattle’s wet, mild climate—featuring frequent rainfall, moisture, and changing seasonal conditions—can be especially demanding on exterior materials. For homeowners seeking durability, cost-effectiveness, and a wide range of colours and textures, James Hardie fiber cement siding remains an unbeatable choice. Today, it is widely used throughout the world, including in Seattle and across the United States, particularly in regions exposed to harsh and unpredictable weather conditions.
What Is Fiber Cement Siding Made Of?
Fiber cement (James Hardie®) siding is a composite exterior material made from cement, sand, and cellulose fibers. Cement provides compression strength, while cellulose fibers act as a reinforcing component, improving durability and flexibility.
As a result, the siding is strong, long-lasting, and free of toxic substances. During manufacturing, the surface is formed with the desired texture and then painted, giving the material its finished appearance and long-term protection for Seattle homes.
Advantages of James Hardie Siding
Exceptional durability
James Hardie® siding is engineered to withstand Seattle’s hot, humid climate, including intense sun, heavy rainfall, moisture, insects, and fire. Its multi-material fiber cement composition makes it far more durable than siding made from a single material;
Long lifespan
James Hardie® fiber cement boards are significantly thicker than traditional vinyl siding. While vinyl siding typically measures about 0.05 inches thick, James Hardie® siding averages around 0.5 inches, allowing it to last for decades—often 50 years or more;
Low maintenance
Fiber cement siding requires very little upkeep. Occasional cleaning is typically sufficient, and repainting is usually only needed every 15 years or longer, especially when factory-finished products are selected;
Attractive and versatile design
James Hardie® siding offers a wide range of colours, textures, and profiles that accurately replicate the appearance of wood lapboards, cedar shingles, and shakes—without the maintenance challenges of natural materials;
Fire and weather resistance
Unlike vinyl or wood siding, James Hardie® siding will not warp, melt, or burn when exposed to high heat. Its fire-resistant properties make it a safer option for homes in Seattle.
Environmentally responsible
James Hardie® products are manufactured using sustainable practices and durable materials that reduce the need for frequent replacement, making them an environmentally friendly siding option.
