LP SmartSide Siding: 7 Benefits, Durability & Style Options

LP SmartSide is one of the most popular engineered wood siding options available to Pittsburgh homeowners, delivering the authentic look of traditional wood with the durability, moisture resistance, and warranty backing that natural wood cannot match. Designed and manufactured by Louisiana-Pacific Corporation using their proprietary SmartGuard process, LP SmartSide combines treated wood strands with waxes, resins, and zinc borate to create a siding product that stands up to hail, wind, termites, and Pittsburgh’s freeze-thaw climate. This guide walks Pittsburgh homeowners through the seven core benefits, style options, and how LP SmartSide compares to other siding materials.

• 7 core benefits: From engineered wood durability to the industry-leading 5/50 year warranty.
• Style options and product collections: Lap, panel, vertical, trim, and ExpertFinish prefinished options.
• Comparisons and cost: How LP SmartSide compares to fiber cement and vinyl, plus current Pittsburgh pricing.

What Is LP SmartSide?

LP SmartSide is an engineered wood siding product made from precisely sized wood strands (typically from sustainably harvested aspen) bonded with waxes and resins, then treated with the SmartGuard process for enhanced protection against moisture, termites, and fungal decay. The material is finished with a resin-saturated overlay that resists impact and weather, and comes in 16-foot lengths for fewer seams and faster installation than shorter siding boards.

Unlike traditional wood siding, LP SmartSide is engineered to resist warping, cupping, splitting, and rotting under normal service conditions. Unlike fiber cement, it can be cut with standard woodworking tools and installed with common carpentry techniques, which broadens the pool of qualified installers.

7 Benefits of LP SmartSide Siding

LP SmartSide delivers a distinctive combination of aesthetic and functional advantages that make it one of the most popular engineered wood siding choices for Pittsburgh homes. Each of the seven benefits below explains why it belongs on your consideration list.

1. Engineered Wood Durability

LP SmartSide combines the natural strength of wood strands with proprietary manufacturing that overcomes wood’s traditional weaknesses. The SmartGuard process treats every wood strand with binders, water-resistant waxes, and zinc borate to create a product that resists the moisture absorption and biological decay that limits natural wood siding’s service life. This engineered approach delivers a lifespan approaching 40 to 50 years with proper installation and maintenance.

• Wood strand composition: Precisely sized aspen strands bonded with resins and waxes.
• SmartGuard treatment: Multi-layer protection process integrated into manufacturing.
• Expected lifespan: 40 to 50 years with proper installation and maintenance.
• Structural integrity: Resists warping, cupping, and splitting under normal service conditions.

2. Impact and Weather Resistance

LP SmartSide is engineered to withstand significant impact and weather stress that would damage lesser siding materials. LP rates SmartSide for wind gusts up to 200 mph when correctly installed and impacts from hail up to 1.75 inches in diameter. For Pittsburgh homes exposed to strong summer thunderstorms and occasional hail events, this impact resistance provides meaningful long-term protection.

• Wind resistance: Rated for gusts up to 200 mph with correct installation.
• Hail resistance: Withstands hail impact up to 1.75 inches in diameter.
• Freeze-thaw performance: Engineered to resist freeze-thaw cycle damage.
• Full weather protection: Resin-saturated overlay adds an additional weather barrier.

3. Moisture, Termite, and Fungal Decay Resistance

The SmartGuard process includes zinc borate treatment that protects LP SmartSide against termite damage and fungal decay, two of the leading causes of natural wood siding failure. The water-resistant waxes and resin overlay also prevent the moisture absorption that leads to swelling, warping, and biological breakdown. This engineering approach lets LP SmartSide perform in wet climates where traditional wood siding would fail within a decade.

• Zinc borate treatment: Multi-layer defense against termites and fungal decay.
• Moisture-resistant waxes: Prevent water absorption into the wood strands.
• Resin overlay: Additional weather barrier on the exposed surface.
• Suitable for wet climates: Performs well in humid or freeze-thaw environments.

4. Industry-Leading Warranty Coverage

LP SmartSide products come backed by an industry-leading 5/50 Year Transferable Limited Warranty that gives homeowners strong confidence in the material’s long-term performance. This warranty includes a 5-year 100 percent labor and material replacement feature followed by a 50-year prorated material warranty, and the warranty is transferable to the next homeowner, which supports long-term resale value.

• 5-year full coverage: 100 percent labor and material replacement for the first 5 years.
• 50-year prorated material: Continued material coverage on a prorated basis after year 5.
• Transferable: Warranty transfers to the next homeowner for continued protection.
• Mix-and-match flexibility: Warranty remains valid even when combined with other siding materials.

The LP SmartSide 5/50 Limited Warranty includes a five-year, 100 percent labor and material replacement feature and a 50-year prorated material replacement feature, backed by the SmartGuard process engineered to protect against fungal decay and termites.

5. Lower Cost Than Fiber Cement

LP SmartSide typically costs less than James Hardie fiber cement while delivering comparable durability and appearance quality for most residential applications. For Pittsburgh homeowners seeking a premium engineered siding without the higher price tag of fiber cement, LP SmartSide represents a strong middle option between vinyl and fiber cement. The material cost savings can be significant for whole-home siding replacements.

• Cost advantage: Typically $2 to $5 per square foot less than James Hardie fiber cement.
• Whole-home savings: Meaningful savings across a full siding replacement.
• Premium performance at mid-tier price: Engineered wood durability without fiber cement pricing.
• Value comparison: Better cost-value ratio than natural wood siding.

6. Easy Installation with Standard Woodworking Tools

LP SmartSide cuts, nails, and installs like traditional wood using standard carpentry tools, which broadens the pool of qualified installers compared to fiber cement (which requires specialized cutting equipment and dust management). This installation ease often translates to lower labor costs and faster project completion for Pittsburgh homeowners.

• Standard tools: Cuts with regular circular saws and installs with standard nailers.
• Lightweight handling: Lighter than fiber cement, reducing installer strain and breakage.
• Faster installation: 16-foot lengths reduce seams and speed up installation.
• Broader contractor pool: More contractors qualified for LP SmartSide than fiber cement.

7. Design Flexibility and Authentic Wood Appearance

LP SmartSide is available in multiple textures including authentic cedar grain and brushed smooth, offering the visual warmth of natural wood without the maintenance burden. The product also comes in ExpertFinish prefinished panels available in 16 baked-on colors, or unfinished for on-site painting. This flexibility supports both traditional and contemporary Pittsburgh home styles.

• Texture options: Cedar grain, brushed smooth, and other authentic wood textures.
• ExpertFinish prefinished: 16 factory-applied colors with baked-on finish.
• Unfinished option: Site-painted for full color customization.
• Both horizontal and vertical applications: Supports lap, panel, and board-and-batten styles.

Style Options and Product Collections

LP SmartSide is available in multiple product collections designed for different applications and aesthetic preferences. Understanding the options helps you pick the right product for your home style.

• LP SmartSide Lap Siding: Traditional horizontal lap siding profile in cedar grain or brushed smooth texture; the most popular collection.
• LP SmartSide Panel & Vertical Siding: Large-format panels for vertical or board-and-batten installations, popular on modern farmhouses and contemporary designs.

LP SmartSide vs. Other Siding Materials

Understanding how LP SmartSide compares to other common siding materials helps you make the right selection for your home and budget.

• LP SmartSide vs. James Hardie fiber cement: LP costs less and installs faster; James Hardie offers better fire resistance and slightly longer manufacturer warranty (30-year non-prorated). Both deliver strong long-term durability.
• LP SmartSide vs. vinyl siding: LP delivers authentic wood appearance and better durability; vinyl costs less and never needs painting. LP is a step up in both appearance and price.
• LP SmartSide vs. natural wood: LP resists rot, insects, and warping that plague natural wood; natural wood offers pure authenticity but requires significantly more maintenance.
• LP SmartSide vs. cedar shake: LP shake collection replicates cedar appearance at lower cost and much longer lifespan than natural cedar.
