Introducing the HardieZone® System
James Hardie is unveiling a new concept — siding that's engineered for climate. We call it The HardieZone System. It provides siding with specific performance attributes relative to the climate where the product is being used. So say goodbye to the days of one-siding-fits-all. James Hardie now gives you the ability to put the optimum siding on a project regardless of your location.
The Science Behind the Siding
We based The HardieZone System on the eight individual climatic variables that primarily affect long-term performance of siding. Using these factors we arrived at ten distinct climatic zones. Though different, we found common variables in certain regions, allowing us to engineer the HZ5® product line for zones 1 through 5 and the HZ10® product line for zones 6 through 10.
