LP Smart Siding Vs Hardie Board: A Comprehensive Comparison

Choosing between LP Smart Siding vs Hardie Board isn’t easy. Both promise durability, style, and protection. But every home is different, and what works beautifully for one family might not be the best fit for another.

Pick the wrong one for an Auburn siding installation, and you could end up spending more on upkeep or losing the look you love. Homeowners deserve clarity, not confusion.

In this post, we’ll explain how LP SmartSide and Hardie Board differ in durability, cost, and appearance and help you make a confident investment for your home’s exterior.

LP SmartSide vs Hardie Board: The Basics

Before diving into the pros and cons, it’s helpful to understand what makes each product unique.

LP SmartSide (Engineered Wood Siding)

LP SmartSide is made from engineered wood strands coated with resin and zinc borate, then bonded with a water-resistant wax. This formula gives it the natural look of wood with added strength and resilience.

It’s also lighter and easier to work with, which often means faster installation times.

Hardie Board (Fiber Cement Siding)

Hardie Board, manufactured by James Hardie, is a fiber cement product composed of cement, sand, and cellulose fibers.

It’s non-combustible, long-lasting, and extremely resistant to fire, moisture, and pests. Homeowners choose Hardie Board for its solid feel and proven reputation for longevity.

Durability and Weather Resistance

Both LP SmartSide and Hardie Board are designed to stand up to tough conditions, but they perform slightly differently under various climates.

• LP SmartSide offers excellent impact resistance thanks to its engineered wood structure. It’s flexible and can withstand hail or debris better than some rigid materials. However, because it’s wood-based, long-term exposure to moisture without proper maintenance could shorten its lifespan.

• Hardie Board excels in fire resistance and humidity control. Its cement composition makes it highly durable, non-combustible, and impervious to rot, warping, and termites.

In Northern California’s dry, warm climate, both perform exceptionally well. However, if your home is located in an area prone to wildfires or high humidity, Hardie Board offers the best long-term protection.

Maintenance and Longevity

When comparing siding materials, maintenance is a big factor.

• LP SmartSide needs to be repainted or refinished roughly every 5–10 years, depending on exposure and paint type. Regular inspection of joints and caulking is important to prevent water intrusion.

• Hardie Board, especially when paired with ColorPlus® Technology, holds its paint color longer and resists chipping or fading. It can go 15 years or more before needing a repaint.

In terms of warranties:

• LP SmartSide: 50-year limited warranty on substrate, 5-year finish warranty.

• Hardie Board: 30-year limited warranty, 15-year finish warranty on ColorPlus coatings.

With proper care, both materials can last 30–50 years, but Hardie’s lower maintenance schedule can make it more convenient for busy homeowners.

Aesthetic Appeal and Style Options

Both brands offer a wide selection of colors and profiles that fit various architectural styles.

• LP SmartSide is ideal if you love the warm, natural look of real wood. It’s available in lap, panel, board & batten, and shake styles. This is perfect for craftsman, farmhouse, or traditional homes.

• Hardie Board offers a smoother, more uniform appearance, popular for modern or coastal-style homes. The ColorPlus® finish ensures consistent color application straight from the factory.

Cost Comparison

Price is often the deciding factor when choosing between LP SmartSide and Hardie Board.

• LP SmartSide: Typically 10–20% more affordable in material and labor costs. Its lightweight panels make installation faster, which can save on labor expenses.

• Hardie Board: Slightly more expensive due to its heavier weight and need for specialized cutting tools, but it can pay off over time with longer lifespan and less frequent repainting.

While LP SmartSide wins in upfront affordability, Hardie Board delivers better long-term value for homeowners planning to stay in their home for decades.

Environmental Considerations

Eco-conscious homeowners will appreciate that both siding options have sustainable features.

• LP SmartSide is made from fast-growing, renewable wood sources, and its production process produces fewer greenhouse gases compared to fiber cement manufacturing.

• Hardie Board is crafted from natural and durable materials, extending its service life and reducing replacement waste.

Both companies have green certifications and are committed to environmentally responsible manufacturing.

Fire, Pest, and Moisture Resistance

• Fire Resistance: Hardie Board is non-combustible, meaning it won’t ignite even when exposed to direct flame – a big plus for wildfire-prone regions. LP SmartSide is treated wood, so while resistant, it’s not fireproof.

• Pest Resistance: LP SmartSide’s zinc borate treatment protects against termites and fungal decay, but Hardie’s cement composition is entirely pest-proof.

• Moisture Control: Both perform well with proper installation and sealing, but Hardie’s fiber cement structure has the edge in high-moisture environments.

Installation Process

The installation experience differs due to the materials’ weight and cutting requirements.

• LP SmartSide: Lightweight, easy to cut with standard tools, and quicker to install. This is ideal for remodeling projects on a tight timeline.

• Hardie Board: Heavier, requiring diamond-tipped tools and dust control measures. Installation takes longer but results in a highly durable and stable finish.
