Cement boards are building materials made from a mixture of cement and reinforcing fibers. They are commonly used as a backing for tiles in areas like bathrooms and kitchens, providing a stable and moisture-resistant surface. Their durability makes them a popular choice for both residential and commercial construction. These boards are typically available in various sizes and thicknesses, allowing for flexibility in different projects. They are often used in conjunction with other materials, such as drywall and fiberglass, to create a strong and long-lasting structure. Cement boards help prevent mold and water damage, making them ideal for wet environments.
