Protect everything inside, from everything outside.
James Hardie fiber cement siding is engineered to stand up to the elements, and stand out in your neighborhood.
Siding Performance and 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®.
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 a semi-arid to arid climate with mild winters and hot summers with extreme UV exposure. Our HZ10 products are formulated with the highest quality raw materials to help resist cracking, splitting, rotting and swelling.
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 siding and trim products on the market.
Moisture & Rot Resistance
| Water can damage your home like nothing else can. It may be gradual, but it is relentless, and can cause siding to swell and crack, lose paint and lead to mold if not properly managed. This is where James Hardie stands out from its competitors. |  |
 |
Wood-based siding has a tendency to expand, buckle or crack when repeatedly exposed to cycles of precipitation and drying. James Hardie products are specifically engineered to withstand damage from moisture and rot, and will hold their own, come rain, sleet, or snow. |
Durable Over Time
| One thing’s for sure: As the years go on, we all show signs of aging. But since James Hardie products are created to stand up to the demands of your specific climate, they will look great for years, potentially saving you time and money. |  |

This photo of wood siding shows how it can be susceptible to moisture and harsh weather conditions and tends to expand and peel over time. With the James Hardie's added benefit of ColorPlus® Technology—a baked-on color option that resists fading—your siding will look great without excessive maintenance. |
Fire Protection
| In case of a fire, you want to know that walls of your house will protect you while your family seeks safety. Fire feasts on wood, and it melts vinyl almost instantly. But James Hardie siding will not ignite when exposed to a direct flame, nor will it contribute fuel to a fire. |  |

Shown here, HardiePlank® lap siding holds up during a home fire and the home's interior is not penetrated. No wonder James Hardie siding is recognized by fire departments nationwide.* *James Hardie siding complies with ASTM E136 as a noncombustible cladding and is recognized by fire departments across the U.S. including Marietta, GA, Flagstaff, AZ and Orange County, CA. Fiber cement fire resistance does not extend to applied paints or coatings, which may be damaged or char when exposed to flames. Because James Hardie products are non-combustible, many insurance companies offer a discount. We recommend sharing fiber-cement siding's fire-resistance qualities with your insurance carrier. |
Insusceptible to pests
| Mother Nature’s creatures can wreak havoc on some types of siding. Because it’s wood, OSB or wood-composite siding can be pecked by birds and damaged by insects. |  |

Weather Withstanding
| Severe weather will test the strength of your home. Hail and blizzards hit hard and fast. Extreme droughts and relentless heat can go on and on. Your choice of siding, along with proper installation, can help your home stand up to these unpredictable elements. |  |
