Performance & Durability
Siding is exposed to Mother Nature all day, every day, for years. Weather, water, time, fire and pests—all can lead to trouble. That’s why James Hardie’s hardworking products are engineered to stand up beautifully, whatever the elements.
Bad weather can strike at any time. So we test our products to better withstand worst-case scenarios: 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®.
A HARDIEZONE® FOR EVERYONE
After studying the long-term effects that different climates have on siding, we 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.
Your region has significant seasonal temperature variations and year-round precipitation. Our HZ5 products are formulated with the highest quality raw materials and proprietary additives to reduce moisture intrusion. This helps prevent your siding from growing mold, shrinking, swelling and cracking.
The things we value most should last the longest. That's why we invented fiber cement and remain committed to continually raising the bar for the rest of the industry. For decades, James Hardie has made the most beautiful, durable fiber cement products on the market.
