Fiber cement siding is a durable and low-maintenance material commonly used to cover the exterior of houses and, in some cases, commercial buildings. It's manufactured with cellulose fibers, cement, and sand, making it long-lasting and durable.

What Is Fiber Cement Siding Made Of?

Certain manufacturers use different ingredients to make fiber cement siding, but most include Portland cement (limestone, clay, and iron), sand or fly ash, water, and cellulose fibers or wood pulp. Some manufacturers add a few proprietary ingredients for binding and durability.

Benefits of Fiber Cement Siding

Durable and low maintenance: Manufacturers offer some warranties lasting up to 50 years, a testament to the material's longevity. It's easy to care for because it holds up against rot, insects, fire, and inclement weather.

Rot-resistant: Since it's water resistant, it resists rot.

Insect and animal resistant: It's inedible to insects and birds, unlike wood, which attracts termites, carpenter ants, beetles, and woodpeckers.

Fireproof: This product replaced asbestos siding due to its fire resistance.

Does not require repainting: It's a fade-resistant material. If you paint over it, you might need to repaint it in five to 10 years. Otherwise, its finish lasts more than 15 years.

Insulating: Fiber cement board is also energy efficient and, to a small degree, contributes to insulating your home.
