Hardiplank and Hardipanel fiber-cement exterior sidings are durable, attractive alternatives to traditional wood composite, cedar, vinyl, brick or stucco sidings.

Combining the look and warmth of natural wood with the durability of fiber-cement, Hardiplank and Hardipanel resist damage from extended exposure to humidity, rain, snow, salt air and termites. They are dimensionally stable and under normal conditions will not crack, rot or delaminate.

Hardiplank and Hardipanel install just as easily as natural wood siding - but offer a lifetime of low maintenance backed by a 50-year product warranty.

Ideal for residential and light commercial applications, Hardiplank lap siding is available factory primed in four attractive profiles. A variety of widths provide regional design flexibility.

Hardipanel vertical siding has excellent structural and impact properties and can be used as a shear panel. It is available in three sheet sizes and four distinct textures.

James Hardie also offers finishing touches like Hardisoffit and Harditrim in textures to complement the siding of your choice.
