Design perk: Premium vinyl siding is 5/100 of an inch thick, but James Hardie fiber cement siding is five times thicker and can withstand winds up to 150 mph.
Our engineers hit the books hard, for years. After studying the long-term effects that climate has on siding—hurricane winds, extreme droughts, extreme temperatures, golf ball-size hail and flooding—we engineered our products to help resist distinct, regional weather conditions. Since inventing fiber cement siding more than 30 years ago, we’ve spent millions to advance our products, especially when it comes to withstanding environmental issues. Both our siding and trim are engineered for climate—sorry Mother Nature, you’re not going to win this one.
Within the United States, there are two distinct HardieZone climates—HZ5® and HZ10® product zones. The HZ5 product line caters to areas where snow and ice are all too common and require withstanding cold, wet winters, which can take a toll on any home. The HZ10 product line resists the effects of heat, humidity, sun and rain. James Hardie siding is the ideal choice when considering the harsh effects of your region’s weather. No matter where you live, we’ve formulated an exterior home product that is right for your particular zone in a style and color that fits your aesthetic.
