What Is Fiber Cement Siding? A Guide to Costs, Pros, and Cons

Are you comparing siding options for a new build, replacement project, or exterior remodeling job? There are several choices on the market, and fiber cement is a popular one. But what is fiber cement siding? It’s a type of engineered siding with a strong reputation for durability, fire resistance, and the ability to mimic the look of wood without the same vulnerabilities of traditional wood siding. 

For many homeowners, fiber cement siding sits in the middle ground between cost-effective materials and premium exterior finishes. Below, we’ll break down what you should know before choosing fiber cement or another type of siding for your home’s exterior. We’ll explore what it’s made of, the different styles available, benefits of fiber cement siding, key drawbacks to be aware of, and how it stacks up against other siding options.

What Is Fiber Cement Siding?

Fiber cement siding is a composite building material composed of a blend of Portland cement, sand, water, and cellulose fibers (which are typically derived from wood pulp). Manufacturers combine these ingredients to create a dense, durable material that can be formed into siding and other products. Most fiber cement products are produced by mixing the ingredients, forming them into sheets or planks, applying a texture, and then curing them in a high-pressure steam autoclave.

Fiber cement siding is designed to offer the appearance of more traditional materials, like wood siding, while improving versatility and performance in areas such as moisture, pest, and fire resistance. Homeowners often choose it when they want a high-quality type of siding with strong visual appeal and a longer lifespan than wood. There are several brand names available, with Hardie Board among the most well-known. 

Some homeowners have concerns about asbestos in fiber cement, but not to worry. Modern fiber cement products do not contain asbestos, although that rumor does circulate from time to time because some older cement-based materials similar to fiber cement used to be made with asbestos. 

Types of Fiber Cement Siding

Fiber cement siding isn’t a single product but rather a category that includes several popular siding styles. Since each style is suited to different looks and applications, we’ll explore some of the most popular options below.

Lap Siding

Lap siding is one of the most common forms of fiber cement. These long, horizontal planks overlap one another to create a classic residential siding look. If you picture the traditional exterior on many American homes, lap siding is probably what comes to mind.  Fiber cement lap products often feature texturing designed to resemble a painted wood finish, offering the warmth of the natural grain with less vulnerability to termites, rot, and weather-related wear. 

Siding Panels

Siding panels are larger sheets of fiber cement board that can be used to create a variety of looks. For example, homeowners sometimes use them to create a sleek, flat siding look for modern homes. Fiber cement panels are also a popular choice for creating the board-and-batten look when paired with smaller planks used as battens. Either way, panels offer a clean architectural look that’s flexible enough to work with modern and traditional exteriors alike.

Shingles

Fiber cement shingles are often used on accent walls, gables, and homes that aim for cottage, Cape Cod, or other historic styles. They add texture and visual interest to homes while still offering the same core material benefits as other fiber-cement products: fire, pest, and moisture resistance.

What Are the Benefits of Fiber Cement Siding?

There’s a reason why fiber cement siding is popular among contractors, builders, and homeowners. It offers many advantages over some other popular types of siding, such as wood and vinyl. We’ll explore each of these next.

Durability

Durability is one of the biggest selling points of fiber cement. It’s made to hold up well against harsh weather, including wind, rain, and fluctuating temperatures. It generally outperforms wood against moisture and pests, and surpasses vinyl siding against wind, hail, impact damage, and extreme temperatures, which can cause vinyl to warp. In fact, where durability is concerned, steel siding is among the few that can outmatch fiber cement with even better resistance to moisture, temperature extremes, wind, impact damage, and pest damage.

Fire Resistance

Like metal siding, fiber cement siding is one of the very few options that is non-combustible. This is a good perk to have since it can protect your home from errant sparks from your grill or fire pit. In wildfire-prone areas, fire-resistant siding can improve a home’s resistance to fire exposure, especially when combined with other fire-safe building practices. Since insurance adjusters factor fire risk into your homeowner’s insurance rate, it can also help you reduce insurance costs.

Appearance

Fiber cement is valued for its aesthetic appeal, especially when manufactured with realistic wood-grain texturing. For many people, achieving these looks while also gaining the benefits of a durable material is a major advantage. In fact, that’s why TruLog’s steel siding also offers hyper-realistic wood grain textures and finishes — so that homeowners can get the curb appeal of real wood without the headaches.

Maintenance

Fiber cement siding also requires less maintenance than some other types of siding — especially wood. While fiber cement siding can be damaged by moisture, that damage is relatively rare so long as you keep up with routine maintenance like caulking or repainting when you spot chipping paint. It resists rot and warping better than wood, though improper installation or prolonged moisture exposure can still cause damage.

While fiber cement siding is a low-maintenance option, some options require even less maintenance. Steel siding, like TruLog, stands out as the strongest alternative. Whereas fiber cement siding should be cleaned regularly and repainted every 10 to 15 years, TruLog steel only needs to be rinsed off once or twice a year, and it never needs to be repainted.

What Are the Drawbacks of Fiber Cement Siding?

No type of siding is perfect. Fiber cement siding has a few trade-offs to consider before you commit. We’ll explore those next.

Weight

The biggest disadvantage of fiber cement siding is its weight, especially compared to vinyl siding or durable alternatives like steel. The extra weight affects everything from the installation process to shipping, handling, and labor, making your project more expensive overall. That’s doubly true if your home needs extra structural reinforcement to support the weight of fiber cement, which can skyrocket your siding installation costs. 

Installation

Fiber cement siding also requires a more specialized installation process than many other siding materials. The planks and sheets are harder to cut, requiring specialized saws and drill bits, and they’re less forgiving of small mistakes. Installing fiber cement siding improperly can lead to moisture management, performance, and even warranty problems.

Edge Damage

Fiber cement siding is much more moisture-resistant than wood siding. While all siding systems depend on proper installation to prevent water intrusion, both steel and vinyl siding are made from completely water-resistant materials. The trouble with fiber cement is that moisture can seep in when the surface coating or board itself gets nicked around the edges. Installers must take care to avoid damaging those areas, and you’ll need to routinely check for breaks in the paint since the coating protects the materials from moisture.

Maintenance

Fiber cement siding does have a reputation for being low maintenance, but unlike steel siding, it isn’t completely maintenance-free. If you have vertical board and batten siding, you should routinely inspect caulking around the battens to ensure moisture can’t get behind them. While it’s available pre-painted, fiber cement should also be repainted every 10 to 15 years, and you’ll need to keep an eye on edges to touch up paint to ensure the material stays sealed against moisture.

How Does Fiber Cement Siding Compare to Other Types of Siding?

Choosing a siding material usually comes down to priorities. Some homeowners care more about upfront cost, while others prioritize durability, energy efficiency, fire performance, maintenance needs, or longevity. To see how fiber cement siding compares to other siding options in these areas, check the chart below.
