Hardiplank is more expensive than nearly any other siding. However, it is comparatively much more durable than vinyl or traditional wood boards, as it is resistant to insects, fire, rot, and harsh weather. James Hardie, the company that produces HardiPlank, provides 50-year warranties on its siding.
HardiPlank is fiber-cement siding composed of a combination of cellulose fibers and cement particles. Hardie boards are extremely durable and long-lasting. They are resistant to both fire and insects and can withstand the salt spray of coastal environments. HardiPlank siding is customizable for the buyer's climate and weather conditions. By contrast, vinyl siding is fairly durable but lacks the customization aspect, and wood options are vulnerable to rotting and weather. Brick is comparable in terms of durability.
HardiPlank is fire-resistant thanks to its composition, which includes not only cement but also sand. Home insurance companies often offer sizable discounts on homes with Hardie boards because they are less vulnerable to fire. Vinyl and wood are both highly combustible, but brick is also fire-resistant.
Hardie boards usually need to be repainted every 15 years. Vinyl cannot be repainted, wood usually requires painting more frequently, and brick is usually not painted.
The cost of a Hardie board is higher than that of other siding products because of the quality of the board and because installation is comparatively more difficult. Typically, a homeowner spends 40 percent more on HardiPlank than he would on vinyl siding.
