Full Answer

HardiePlank siding is a board siding made of fiber cement. This composition makes the siding heavier compared to other types of siding materials and requires the use of special saws to cut the boards. Also, the board needs to be handled carefully as it's brittle and susceptible to splitting. As a result, installing a HardiePlank siding is more labor and time intensive.

Additionally, HardiePlank siding must be periodically repainted, and the finish of the siding comes with only a 15-year guarantee. The cost per square foot of the siding is nearly double the cost of other siding types.

Since the fiber cement absorbs moisture and dries slowly, it encourages mold growth over time. Moisture in the boards can also cause the latter to crack in cold weather conditions. The material, with its low thermal resistance, is a poor insulator and does little to keep the street noises away.

Silica dust released when the HardiePlank siding is cut can cause respiratory problems. Installers control the release of silica dust by wetting the planks before cutting.
