Sanded surface, through-color fiber cement board is a type of architectural panel used for building facades and other exterior and interior wall applications. It's known for its unique aesthetic and durability, offering a timeless and modern look.
Key Characteristics
Through-Color: Unlike traditional fiber cement boards that are coated with a surface color, these boards have a consistent pigment throughout the entire material. This means the color is the same on the surface as it is on the core, and it won't fade or show a different color if it's scratched or chipped.
Sanded Surface: The manufacturing process includes a sanding step that exposes the natural texture and aggregates of the fiber cement, creating a unique, subtle, and raw finish. The fine sanding lines give the material a dry and lively appearance.
Composition: The boards are typically made from a mixture of natural materials, including Portland cement, cellulose fibers (often from wood), quartz sand, and water. These are combined, cured in a high-temperature autoclave, and then sanded.
Durability: These panels are highly durable and are resistant to various environmental factors, including fire, water, rot, insects, and extreme weather conditions. They are also known for their high strength and long service life.
Uses and Brands
Common Applications
The combination of through-color and a sanded surface makes these boards popular for a variety of building projects where a high-end, contemporary aesthetic is desired. They're often used for:
Exterior Cladding: As a facade material for homes, villas, public buildings, and industrial structures.
Interior Walls: For creating unique accent walls or panels in both residential and commercial spaces.
Rainscreen Systems: They are frequently used in ventilated rainscreen facade systems, which provide both weather protection and improved thermal performance.
Notable Brands
While many companies produce through-color fiber cement boards, some brands are more widely recognized for this specific type of product.
EQUITONE: The EQUITONE [tectiva] line is a well-known example of a through-color facade material with a sanded surface.
James Hardie: A leading brand in fiber cement siding, they offer a wide range of products, including their Hardie Architectural Collection which features modern paneling options.
Allura: Another top brand that offers various textures and colors in their fiber cement siding product line.
Maintenance and Finishing
A key benefit of through-color fiber cement is its low maintenance. Since the color is inherent to the material, you don't have to worry about the paint chipping or fading. However, to maintain the boards' appearance and longevity, it's still important to follow some best practices:
Cleaning: Regular cleaning with a soft brush and a garden hose is usually sufficient to remove dirt and debris.
Finishing: While the boards are pre-finished and require no further treatment after installation, some manufacturers may apply a clear, waterproof shield to protect and enhance the natural finish.
Sealing: Applying a sealant can add an extra layer of protection against moisture penetration and UV rays, which helps to extend the lifespan of the panels. This is particularly useful for exterior applications.
