What Is the HardieZone® System?

James Hardie siding products are Engineered for Climate®. That means that siding has specific performance features relevant to the climate where it is being used. Regardless of your location, you can count on James Hardie siding to be at optimum performance.

The company bases the HardieZone System on eight individual climatic variables, all affecting the long-term performance of the products. With these factors, James Hardie came about 10 distinct climatic zones. While the regions are different, some still have variables in common, which allowed James Hardie to create the HZ5® product line for zones 1 to 5, and the HZ10® product line for zones 6 to 10.

HZ5® vs. HZ10®

Those who live in climates with freezing temperatures, extreme seasonal weather changes and snow and ice can benefit from the HZ5 product line. This line offers superior paint adhesion and moisture resistance. With this product line, you won’t only have siding that stays efficient in cold, harsh climates, but you’re getting an exterior engineered for your location.

Made for areas that experience hurricane-force winds, the HZ10 product is ideal for the salty air of the coast and excessively humid heat of the Deep South. HZ10 boards feature excellent resistance to cracking, splitting, rotting and swelling.
