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.
