Fiber cement board is a durable, low-maintenance building material used for a wide range of interior and exterior construction projects. Composed of a mixture of cement, sand, and cellulose fibers, it’s known for its resistance to fire, water, rot, and pests.

Exterior Applications

Fiber cement board is most commonly used for a building’s exterior due to its strength and ability to withstand harsh weather conditions.

• Siding and Cladding: This is arguably the most popular use for fiber cement. It comes in planks that mimic the look of wood, as well as in other styles like shingles and large panels. It’s a great, low-maintenance alternative to traditional wood or vinyl siding.
• Trim Boards: Fiber cement is also used for trim around windows, doors, and other exterior features. It provides a durable, non-combustible finishing touch that resists rot and moisture.
• Soffits and Eaves: The material’s moisture and fire resistance make it ideal for protecting the underside of a roof’s overhangs

Interior Applications

The water and mold resistance of fiber cement board make it perfect for rooms with high humidity.

• Tile Backer Board: It’s an excellent underlayment for tile in kitchens, bathrooms, and showers. It provides a stable, rigid surface that prevents the tiles from cracking and keeps moisture from seeping into the walls or subfloor.
• Drywall Partitions: As an alternative to gypsum drywall, fiber cement is used for non-load-bearing interior walls, especially in wet areas.
• Flooring: Thicker sheets can be used as a substrate for flooring, providing a sturdy, rot-resistant base for various floor coverings.
• False Ceilings: Fiber cement boards are used to create false ceilings in both residential and commercial settings, offering fire resistance and a variety of textural finishes.
