Performance and Durability
Bad weather can strike at any time. So James Hardie tests their products to face the worst case scenarios such as: hurricanes, UV rays, snowstorms, and more. But it’s not only extremes that break down siding; the change of seasons does a number on materials such as vinyl (which may crack in the cold) and wood products (which expand and contract with changes in moisture and humidity). Only James Hardie products are Engineered for Climate. After studying the long-term effects that different climates have on siding, James Hardie created the HardieZone system, to ensure that you get the right product for your region. HZ5 products are made to resist wet, freezing conditions. HZ10 products protect homes from heat, humidity, blistering sun and more.
