James Hardie cement lap siding gives the durability needed against the harshest weather climates.  This siding was engineered for areas with hurricane-force winds, salty sea air of the coast, and the brutal, humid heat of the Deep South. Engineered specifically for these climates, HZ10™ boards resist cracking, splitting, rotting and swelling season after season.

Choose this siding for its smooth sleek lines and bead.  Stocked in 8-1/4″ width only.
