Cement Boards: What You Need To Know

Cement Boards: What You Need To Know

Cement boards, also known as fiber cement panels, backer boards, or cementitious backer units (CBUs), are essential for construction projects requiring exceptional durability and moisture resistance. These boards are made from a mixture of cement, sand, and reinforcing fibers, making them highly durable and suitable for challenging environments. With their strength and versatility, cement boards are ideal for a range of indoor and outdoor applications.

Key Features:

  • Moisture Resistance: Cement boards are engineered to withstand water exposure without swelling, rotting, or warping, making them perfect for areas prone to humidity, such as bathrooms, kitchens, and basements.
  • Mold and Mildew Prevention: Thanks to their inorganic composition, cement boards resist mold and mildew growth, ensuring long-term durability and hygiene in damp environments.
  • Impact Resistance: The dense, durable structure of cement boards allows them to withstand heavy impacts, making them ideal for high-traffic areas or applications requiring added durability.

Variants:

  • Fiber Cement Boards: Lightweight and easy to cut, these are perfect for walls, ceilings, and countertops.
  • Reinforced Cement Boards: Stronger and denser, they are used for flooring, exterior cladding, and other heavy-duty applications.

Applications:

  • Tile Backing: Provides a stable, moisture-resistant base for ceramic or stone tiles in showers, tubs, and backsplashes.
  • Exterior Siding: Used as cladding to create durable, weather-resistant exteriors.
  • Underlayment: Strengthens flooring systems, preventing cracks and adding stability for tile or hardwood installations.
  • Fireproofing: Ideal for building areas requiring fire-resistant materials, such as fireplaces or stove surrounds.

Advantages Over Drywall and Wood Panels:

Unlike drywall or wood panels, cement boards do not absorb moisture or swell over time. They provide a reliable, long-lasting solution for construction projects in wet or high-impact areas, offering better resistance to environmental stressors.

FAQ

What are cement boards, and how are they different from drywall?

The cement-based mixture with cellulose or fiberglass fibers in cement board creates a material which offers exceptional resistance to water damage and decay. The lightweight drywall material consists of gypsum plaster between paper layers but lacks the moisture-resistance of cement boards. Los Angeles homeowners select cement boards as their preferred substrate for tile, stone installations in bathrooms, kitchens, and outdoor spaces because they resist water.

What are the advantages of using cement board in Los Angeles homes?

Cement board stands out as the perfect choice for applications with moisture risks or fire dangers because it provides non-flammable properties with water protection and termite defense. The material maintains stability through its durability which enables it to support tile, natural stone, and stucco installations. Cement board's water-resistant properties enable Los Angeles homeowners to use it in shower walls, exterior cladding, and backsplash applications because drywall would fail when exposed to moisture.

What’s the best delivery option for heavy cement boards?

For heavy items like cement boards, we recommend Curbside delivery if you have someone on site to move them into place, or White Gloves service if you need our team to carry them indoors. If you already have a crew to unload, Truck Bed delivery would be the most reasonable choice. All options ensure safe unloading without damaging the product.

When should you choose cement board over drywall in Los Angeles construction?

Cement board should be used in areas that face water exposure or tile or stone installation. Its combination of moisture resistance and stability makes it suitable for bathrooms, laundry rooms, kitchen backsplashes, and exterior walls. Los Angeles homeowners select cement board for stucco installation and patio tile backer because it withstands degradation from rain and humidity.

Can cement board be used on ceilings or walls for general interior applications?

The installation of cement board proves possible for interior walls and ceilings, yet its weight and insufficient insulation capabilities prevent its use for full room construction. The product functions optimally as a base material for tile and stone installations. Standard walls and ceilings require ½-inch drywall because it serves as a cost-effective solution that is also lighter in weight. Cement board is applied by Los Angeles contractors exclusively in wet areas but gypsum boards serve all other construction needs.
