Fiber-Cement Siding Information

Composed of sand, cement, and cellulose fiber, fiber cement is an excellent option for homeowners who appreciate the look of wood but who may not have the time and money required to maintain it. Fiber-cement siding is available from a number of manufacturers— James Hardie and CertainTeed are among the most popular—and provides the appearance of wood in a material that is termite resistant, non-combustible, and warranted by most of its manufacturers for 30 to 50 years. Fiber cement does not swell in warm climates and will not decay or rot. It is extremely stable and does not attract insects because, unlike wood, the material is not digestible. Most fiber cement is sold pre-painted and comes in a variety of colors. Fiber-cement sheets are also sold unpainted, which the industry recommends should be factory primed and then painted at installation; a topcoat that is 100 percent acrylic is the favored paint. And while the siding will need to be repainted at approximately 15-year intervals, the paint on fiber-cement generally lasts longer than on natural wood products because cement expands and contracts less than wood does.
