Why Is Hardie Considered By Many To Be The #1 Fiber Cement?


You must be considering new Fiber Cement Siding for your home.

It’s a serious investment, where, unfortunately, there can be a ton of unknowns. And this margin for error can end up costing you a ton of money and headaches to get things fixed.

You might not have the time to research a massive national/international industry and get to the bottom of all the science involved in modern fiber cement siding.

When you start searching around online, it’s mainly fluff, pure marketing content, or paid advertorials masquerading as educational material.

You just want to know the best fiber cement product line for your home, your tastes, and your budget.

One of the biggest names you start coming across is, of course, the James Hardie Corporation.

You’ve likely heard the name before, and you’ve probably seen this kind of siding on countless homes but just didn’t know it at the time. How could you?

  • The James Hardie corporation isn’t just in America but employs a diverse global workforce in North America, Europe, Australia, New Zealand, and the Philippines.
  • They are EARTH’S #1 producer of high-performance fiber-cement building materials.

Just A Smidgen Of History

Most homeowners we work with here in the Greater St. Louis Metro area think that Hardie fiber cement is a U.S. company. It isn’t. They’ve just had a huge presence in America for a long time, and their products are literally all over the place in residential areas from sea to shining sea.

Here’s a couple of paragraphs on their history directly from their main website just for good measure, so you can see Scottish-Australian (the company is based in Ireland), roots:

“The predecessor of our modern company was established in 1888, when the enterprising young James Hardie left his family’s tannery business in Scotland and immigrated to Melbourne, Australia, in search of new opportunities. Hardie leveraged his experience to start a business importing oils and animal hide tanning products.”

“Hardie was joined in Melbourne in 1892 by fellow Scotsman Andrew Reid, who became a full partner in the business in 1895. Hardie retired in 1911 and sold his half of the company to Reid, whose family led the expanding business from 1911 until 1995 when his grandson John B. Reid retired.”


A business 133+ years and running.

What does this mean?

It means you’re not getting some rinky-dink product from a new upstart. You’re dealing with a residential construction product that’s been developing for a very long time. And, you’re dealing with a WELL-established company.

For example, while basic fiber cement is made of a few simple ingredients — Portland cement, sand, water, and cellulose fibers — they have a cutting-edge proprietary blend that provides more features for your home:

  • Full Systems: Hardie has a complete line of options, not just siding planks; lap siding, shingle siding, vertical, trim boards, weather barrier, cement board, etc.
  • Non-Combustible: When exposed to flame, fiber cement will not ignite or add fuel to the fire. But, heat can still transfer through it. Fiber cement is typically considered a specialty masonry product similar to materials like brick, stucco, and stone.
  • Long-Lasting Durability: As long as you give it the proper care, which indeed is minimal compared to other forms of siding, your new Hardie siding should easily outlast its warranty. We’re talking around 50 years!
  • Unappealing To The Wildlife: Woodpeckers? Nope, they won’t try and peck the stuff. Termites? Nope How about carpenter ants? Nope. There just aren’t as many critters that want to try and eat cement.
  • Professional Installation: Because it’s not cheap, poorly-made siding, not just anyone can make it look outstanding. We adhere to a strict No-Stone-Unturned Siding Installation approach to ensure it’s perfect every time.
  • Climate Specific: They design siding for our specific area of the country.

They call it the HardieZone System. All this means is that they make adjustments in their blends and features for hotter and colder climates. Here’s what the two core zones look like:

As you can see, here in St Louis Metro, we’re in the HZ5 zone.

Without getting into all the material construction science, it’s designed to fight the cold, snow, and ice we deal with here vs. what someone who lives further to the south or southwest might deal with on a normal basis.

“The HZ5® product line is right at home in climates with freezing temperatures, extreme seasonal temperature variations, snow, and ice… 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.”
