Fiber Cement vs. Engineered Wood Siding

White James Hardie Fiber Cement Siding
When it comes to selecting the perfect siding for your home, two popular choices stand out: fiber cement and engineered wood. Both offer durability and aesthetic appeal, but they differ in several key areas, including warranty length, weight, material composition, and appearance. Let’s dive into the details of LP SmartSide and James Hardie siding to help you make an informed decision for your home improvement project.

Material Composition

LP SmartSide

LP SmartSide siding is made from engineered wood, specifically a blend of wood strands or fibers combined with resin binders and wax. This composition enhances its strength and resistance to moisture, termites and pests, and fungal decay. For this reason, it was our choice when a customer was battling issues with woodpeckers burrowing holes in his cedar siding: feel free to read more about Cedar vs. LP SmartSide.
Additionally, LP SmartSide features a SmartGuard® process, adding zinc borate to further protect against the elements.

James Hardie

James Hardie siding is crafted from a mix of cement, sand, and cellulose fibers. This combination results in a highly durable material that resists fire, rot, and pests. Fiber cement siding is renowned for its ability to withstand harsh weather conditions, including intense heat and freezing temperatures.

Appearance

LP SmartSide

LP SmartSide offers a wide range of styles and textures, allowing homeowners to achieve a customized look. Engineered wood siding typically has fewer seams, providing a more seamless appearance. While it offers a pleasing aesthetic, some homeowners find that it lacks the authentic wood-like texture that fiber cement can provide. We think it was the perfect choice for a complete home renovation of this gorgeous home in Palatine, IL.

Warranty Length

LP SmartSide

One of the standout features of LP SmartSide is its lightweight nature. Engineered wood siding is significantly lighter than fiber cement, making it easier to handle and install. This can reduce labor costs and installation time, providing an overall smoother construction process.

James Hardie

James Hardie fiber cement siding also boasts an impressive warranty. Most James Hardie products come with a 30-year non-prorated limited warranty. This means the warranty remains robust throughout its duration, offering consistent protection. Additionally, James Hardie provides a 15-year warranty on the finish, ensuring the siding’s appearance remains intact over time.

Weight

LP SmartSide

One of the standout features of LP SmartSide is its lightweight nature. Engineered wood siding is significantly lighter than fiber cement, making it easier to handle and install. This can reduce labor costs and installation time, providing an overall smoother construction process.

James Hardie

Fiber cement siding, such as James Hardie, is notably heavier. The added weight can pose challenges during installation, requiring more manpower and potentially increasing labor costs. However, this weight contributes to the siding’s durability and resistance to extreme weather conditions.

Fire Resistance

LP SmartSide

While engineered wood siding offers many benefits, fire resistance is not its strongest suit. Wood-based materials can ignite and contribute fuel to a fire, making them less ideal for areas prone to wildfires.

James Hardie

James Hardie fiber cement siding excels in fire resistance. It will not ignite when exposed to direct flames, nor will it contribute fuel to a fire. This makes fiber cement an excellent choice for homeowners seeking added protection against fire hazards.

Moisture Resistance

LP SmartSide

Engineered wood siding is designed to resist moisture, but it can still swell and expand when exposed to excessive water and humidity. Proper installation and maintenance are crucial to ensure its longevity in wet climates.

James Hardie

James Hardie products are engineered to resist water and humidity exceptionally well. They stand up to rain, sleet, and snow better than wood-based siding, making them a reliable choice for areas with high moisture levels.

Weather Resistance

LP SmartSide

Engineered wood siding provides good weather resistance but may not perform as well as fiber cement in extreme conditions. It is crucial to consider the local climate when choosing this type of siding.

James Hardie

James Hardie siding is built to withstand the harshest weather conditions, including hurricanes, strong winds, extreme heat, UV rays, snow, and freezing temperatures. Its exceptional durability makes it suitable for virtually any climate.

Pest Defense

LP SmartSide

Engineered wood siding is treated to resist pests, but it can still be vulnerable to woodpeckers and other insects over time. Regular inspections and maintenance can help mitigate these issues.

James Hardie

James Hardie fiber cement siding offers superior pest resistance. It holds no appeal for termites or woodpeckers, ensuring long-lasting protection against pests that can damage traditional wood siding.

Additional Considerations

History and Popularity

Fiber cement siding has been around since the early 20th century and started gaining popularity in the U.S. in the mid-1980s. On the other hand, engineered wood siding was introduced later, in the latter part of the 20th century. Both materials have proven to be superior to traditional wood in terms of durability and appearance.

Installation

Engineered wood, like LP SmartSide, is praised for its ease of installation. It cuts like real wood, accepts nails and screws, and requires only standard woodworking tools. In contrast, fiber cement siding, such as James Hardie, needs specialized tools for cutting and is more prone to breaking or cracking, which can lead to increased material waste.

Panel Length

Fiber cement lap boards typically come in 12-foot lengths. Engineered wood siding, however, can be manufactured in 16-foot lengths, resulting in fewer seams and a faster installation process.

Pricing

Generally, engineered wood siding tends to be less expensive than fiber cement siding. This can make it an attractive option for homeowners looking to balance quality with cost-effectiveness.

Common Installation Issues Found in Both Types of Siding

Incorrect Nailing Practices

  • Wrong Nail Type and Size: A common mistake is using the wrong type and size of nails. It is essential to use 6d (2-inch) or 8d (2 1/2-inch) corrosion-resistant nails. Stainless steel nails are preferred because they do not rust, while galvanized nails are recommended only in areas where they are not exposed, such as under siding overlaps.
  • Improper Nail Placement: Nails should be placed correctly—not too high, too low, or too close to the edges. Incorrect placement can cause the siding to loosen or crack over time.
  • Visible Nail Heads: Exposed nails not only spoil the look but can also compromise the siding’s integrity. A well-done installation should hide nails to maintain a smooth, clean finish.
  • Use of Galvanized Nails in Exposed Areas

Improper Cutting and Sealing

Using inappropriate tools or dull blades can lead to uneven cuts and siding gaps, exposing your home to potential damage. It’s crucial to use the right tools and take accurate measurements for a perfect fit. Additionally, ensure that all cut edges are painted or sealed to prevent moisture infiltration and decay.

Improper Caulking

Many installations fail because of improper caulking around edges and fixtures. Ensure there is a small gap between the siding and metal flashings to allow water to drain away, preventing water damage. Caulking should be applied correctly to allow water to drain away. There should be a small gap between the siding and metal flashings to prevent water from getting trapped behind the siding, which can cause damage over time.

Insufficient Clearance

Siding installed too close to the ground or other surfaces can trap moisture. Ensure there is at least six inches of clearance from the ground and two inches from steps or paths. This helps avoid moisture damage and ensures warranty compliance.

Poor Flashing

Flashing directs water away from the siding. Incorrectly installed flashing can lead to water damage. Properly installed Z, L, and kickout flashings are crucial for preventing leaks. Siding is durable but can be fragile if mishandled. It should be transported and installed carefully to avoid cracks or chips.

Inappropriate Storage and Transportation

Siding materials should always be stored flat, off the ground, and under cover. Exposure to rain or moisture before installation can cause warping or damage to the material, leading to future installation issues. When transporting, ensure that the siding is properly secured and protected from weather elements. Rough handling or exposure to rain during transport can affect the quality and durability of the siding.
Ensuring that your siding is installed by experienced professionals who follow best practices can make a significant difference in its performance and longevity. Taking shortcuts during installation can negate many of the benefits that come with high-quality siding products.
