This will help you make the most informed decision for your Northeast Wisconsin home.
Material Composition: Fiber Cement vs Engineered Wood
Understanding the materials used in James Hardie and LP SmartSide siding is key to deciding which will offer better protection for your home.
Both options have unique properties that affect their durability, maintenance, and appearance.
James Hardie Material Composition
James Hardie siding is made from fiber cement, a blend of Portland cement, sand, and cellulose fibers.
This combination creates a highly durable material that’s resistant to rot, insects, and extreme weather conditions.
- Fiber cement siding is known for its strength and longevity, making it a top choice for homeowners facing harsh climates.
- The composition also includes ColorPlus® Technology, a factory-applied paint finish that helps protect against fading and UV damage.
This fiber cement siding is heavier and more robust than other options like vinyl siding, giving it a solid, long-lasting presence on any home.
LP SmartSide Material Composition

It’s all about deciding which look aligns better with your design preferences.
Installation Process and Ease

The ease of installation for siding can directly affect both the time and cost of your project.
James Hardie and LP SmartSide differ significantly in how they are installed, impacting labor costs and the time required for completion.
James Hardie Installation
Installing James Hardie siding requires specialized skills and tools due to its fiber cement composition.

For homeowners in Northeast Wisconsin, the choice between James Hardie and LP SmartSide could depend on the availability of experienced contractors and the time and budget available for installation.
While James Hardie offers durability, LP SmartSide shines in terms of installation speed and ease.

Fire and Impact Resistance
When it comes to protecting your home, both fire and impact resistance are crucial, especially in regions like Northeast Wisconsin, where severe weather can bring strong winds and debris.
Let’s take a look at how James Hardie and LP SmartSide compare in these areas.
James Hardie Fire Resistance
James Hardie siding is made from fiber cement, which is naturally non-combustible.
This makes it an excellent choice for homeowners seeking added protection against fire hazards.
- Non-Combustible: Fiber cement siding does not ignite or spread flames, providing peace of mind in areas where fire safety is a concern.
- High Heat Resistance: The cement composition helps the siding withstand high temperatures without warping or breaking down.
LP SmartSide Fire Resistance

While it has been treated to resist moisture and pests, it contains organic materials that make it more susceptible to fire.
- Higher Fire Risk: Due to its wood-based construction, LP SmartSide is more likely to burn if exposed to direct flames.
Impact Resistance
Both James Hardie and LP SmartSide offer protection against impacts, but they perform differently under certain conditions.
- James Hardie Impact Resistance: While fiber cement siding is durable, it can be more brittle than engineered wood. In areas prone to hail or debris, James Hardie siding may chip or crack under heavy impact.

In summary, if fire resistance is your top priority, fiber cement siding from James Hardie is the clear winner.
However, if you live in an area with frequent storms, LP SmartSide’s impact resistance may offer better protection against physical damage.
Warranty Comparison
The warranty offered on siding products is an important factor to consider, as it can provide peace of mind and protect your investment.
Both James Hardie and LP SmartSide offer warranties that cover defects and performance, but there are key differences in how they are structured and the level of coverage provided.
James Hardie Warranty
James Hardie siding comes with one of the most robust warranties in the industry, reflecting the brand’s confidence in its fiber cement products.
The coverage ensures long-term protection and is non-prorated, meaning the value of the warranty doesn’t decrease over time.

- ColorPlus Technology Warranty: The factory-applied ColorPlus finish comes with a 15-year warranty against fading, peeling, or chipping.
- Transferable: The warranty is transferable to new homeowners, adding value if you plan to sell your home.
LP SmartSide Warranty
LP SmartSide siding offers a longer overall warranty period, but it is prorated after the first five years, meaning coverage decreases over time.
While the initial coverage is strong, the prorated structure means less protection as the siding ages.
- 50-Year Limited Warranty: LP SmartSide comes with a 50-year limited warranty, but the coverage decreases after the first five years.
- 5-Year 100% Coverage: During the first five years, LP SmartSide provides 100% coverage for labor and materials in the case of any defects.
- Prorated Coverage: After the first five years, the warranty becomes prorated, reducing in value by 2.2% annually through the end of the warranty period.
Key Differences
- James Hardie: Offers consistent, non-prorated coverage throughout the entire 30-year warranty period, ensuring full protection for homeowners.
- LP SmartSide: While the warranty lasts longer, the prorated structure means coverage decreases over time, offering less value in the long term.
