What are the Differences between Pvc Decking and Composite Decking?

When comparing PVC decking to composite decking, the primary difference lies in the material composition and performance in wet environments. PVC decking is made from a 100 percent PVC polymer core, making it completely moisture-impermeable. This prevents the swelling, rot, and mold issues often associated with Nebraska’s wet climates.

Composite decking consists of a blend of wood fibers and plastic (typically a 70/30 ratio). Because it contains wood content, it may absorb some water and has a higher potential for mold compared to its all-polymer counterpart.

Key performance differences include:

• Maintenance: PVC is considered ultra-low maintenance, whereas composite is low maintenance but requires slightly more care than PVC.
• Durability: While both offer 25 to 50 year lifespans and high UV resistance, PVC provides superior resistance to moisture and temperature swings.
• Fire Resistance: Advanced PVC products, such as the TimberTech Vintage Collection, can achieve a Class A Flame Spread Rating, offering enhanced safety compared to traditional materials.

While both options are superior to traditional wood, PVC is the premier choice for homeowners seeking the highest level of moisture protection and the lowest possible maintenance.
