What is Hardyboard?
Hardyboard, also known as cement board or fiber cement siding, is a type of exterior cladding material increasingly popular in construction for its durability and versatility. It’s a composite material consisting primarily of Portland cement, cellulose fibers, and silica sand. These ingredients are combined and formed into large sheets, then cured and finished for installation. The resulting product offers a robust and weather-resistant alternative to traditional materials like wood and vinyl.
Hardyboard Composition and Manufacturing
Hardyboard’s strength and longevity stem from its specific composition. Portland cement provides the binding agent and contributes significantly to the material’s compressive strength. Cellulose fibers, often derived from recycled paper, add tensile strength and flexibility, preventing cracking and brittleness. Silica sand acts as a filler, contributing to the overall bulk and density of the board. The manufacturing process involves mixing these components with water, forming the mixture into large sheets under high pressure, and then curing them in a controlled environment to allow the cement to fully hydrate and harden. This process results in a dense, non-porous board resistant to moisture, rot, and insect infestation. The final product is often treated with a surface coating to enhance its aesthetic appeal and weather resistance.
