Engineered for Climate®
James Hardie provides siding products that are Engineered for Climate®. We call this The Hardie®Zone System. It provides siding with specific performance attributes relative to the climate where the product is being used. As a result, James Hardie gives you the ability to put the optimum siding on a project regardless of your location.HZ5® Fights Cold, Snow, Ice and Worry
The HZ5® product line is right at home in climates with freezing temperatures, extreme seasonal temperature variations, and snow and ice. To ensure its beauty matches its durability, we've engineered the surface for higher performance, giving it superior paint adhesion and moisture resistance. In addition, we've added a drip edge to provide improved water management. So you are not only getting an exterior that performs well in cold, nasty climates. You're getting an exterior engineered just for it.
HZ10® Defies Blistering Sun, Hurricane-Force Winds and Sheets of Rain
Even when Mother Nature isn't very motherly, the HZ10® product line delivers legendary James Hardie durability. 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 hot, humid, tropical storm season.
