Coverage & How Much You Need:

Fit and Compatibility:
Installs as standard lap siding alongside James Hardie fiber cement trim and accessories in the HZ5 climate zone product line. ColorPlus Technology factory-finished options are available in the broader product line if you prefer a baked-on color over field painting.
