Fiber Cement

In Plain English

A durable exterior siding material that looks like wood but resists rot, insects, and fire.

Definition

Fiber cement is a composite exterior cladding material made from Portland cement, sand, and cellulose fibers, designed to mimic the appearance of wood siding, stucco, or masonry while providing superior resistance to moisture, insects, fire, and rot. It is one of the most popular exterior siding materials in residential and light commercial construction. Fiber cement requires factory or field painting and proper installation to perform as intended.

Example

The architect specified fiber cement lap siding to match the historic neighborhood character while meeting the 30-year material warranty requirement.
