Composite Siding Materials and Construction
Composite siding represents a sophisticated blend of engineered materials designed to overcome the limitations of traditional wood siding. The primary components include wood fibers or sawdust, thermoplastic resins (typically polyethylene or polypropylene), and binding agents that create a uniform, durable material.
⚖️ Research from the University of Wisconsin-Madison’s Department of Forest and Wildlife Ecology shows that modern composite materials achieve superior dimensional stability by controlling fiber orientation and resin distribution during manufacturing.
The manufacturing process begins with wood fibers being dried and screened to remove impurities, then combined with plastic resins in precise ratios—typically 50-70% wood fiber and 30-50% plastic resin. This mixture is heated, extruded through specialized dies, and cooled under controlled conditions to create boards with consistent density and strength properties.
The Wisconsin Department of Safety and Professional Services recognizes composite siding materials that meet ASTM D7032 standards for performance in cold climates.
Advanced manufacturing techniques now include co-extrusion processes that create protective caps on composite siding surfaces. These caps, made from 100% polymer material, shield the wood-plastic core from moisture infiltration and UV degradation—critical considerations for Wisconsin’s intense summer sun and winter moisture cycles.
Types of Composite Siding for Wisconsin Homes
Wisconsin homeowners can choose from several composite siding types, each engineered to address specific climate challenges and aesthetic preferences. Understanding these options helps ensure you select materials that will perform reliably in our region’s demanding weather conditions.
✔️ When considering all types of house siding available, composite options stand out for their climate resilience.
Wood-Plastic Composites (WPCs)
Wood-plastic composites represent the most common type of composite siding, combining recycled wood fibers with thermoplastic materials. These boards offer excellent workability and can be cut, drilled, and installed using traditional woodworking tools.
WPCs perform particularly well in Wisconsin’s climate because the plastic component resists moisture absorption while the wood fibers provide structural stability during temperature fluctuations.
Fiber-Reinforced Composites
Fiber-reinforced composites incorporate glass or synthetic fibers for enhanced strength and durability. These materials excel in high-wind areas common in Wisconsin’s prairie regions, offering superior impact resistance against hail and debris.
The fiber reinforcement also reduces thermal expansion and contraction, minimizing gap formation during Wisconsin’s extreme temperature swings.
Recycled Synthetic Fiber Composites
These innovative materials use recycled synthetic fibers combined with polymer binders to create lightweight, durable siding options. Recycled synthetic fiber composites offer excellent resistance to Wisconsin’s freeze-thaw cycles and maintain their appearance longer than traditional wood composites. They’re particularly suitable for homeowners seeking environmentally responsible options without compromising performance.
Engineered Wood Composites
Engineered wood composites utilize specially treated wood strands or chips combined with weather-resistant resins. These materials provide authentic wood grain textures while offering superior moisture resistance compared to natural wood.
In Wisconsin’s humid summers and wet spring seasons, engineered wood composites maintain dimensional stability and resist warping or cupping.
