Composite vs. PVC Decking: Which Is Right for You?

When choosing decking material, one of the biggest decisions is between composite (wood-plastic composite) and PVC (polymer) decking. Both offer low maintenance compared to wood, but they have distinct differences in composition, performance, and cost.

What Is Composite Decking?

Composite decking is made from a blend of wood fibers and recycled plastic. Brands like Trex, TimberTech (composite lines), and Fiberon use this formulation. Composite decking typically has a wood-like appearance and feels more natural underfoot. It's generally less expensive than PVC and holds heat differently. Capped composites add a protective polymer shell that resists staining and fading — most products today are capped on three or four sides.

**Pros:** Natural wood look and feel, lower cost than PVC, eco-friendly (made from 85–95% recycled materials), quieter underfoot.

**Cons:** Can be more susceptible to mold in humid climates (though modern capping helps), heavier than PVC, may fade more over time than PVC.

What Is PVC Decking?

PVC (polyvinyl chloride) decking is made entirely from synthetic polymer and contains no wood fibers. Azek (TimberTech's PVC line) and Fiberon Paramount are leading examples. PVC decking is completely waterproof and offers the best moisture resistance of any decking material.

**Pros:** 100% waterproof, best moisture resistance, lightweight, doesn't support mold or mildew, cooler underfoot with technologies like Cool Touch Technology (Azek), Class A fire ratings available on Azek Vintage, Landmark, and Fiberon Paramount.

**Cons:** More expensive than composite, can get hotter in direct sun (especially darker colors), may feel less natural underfoot, can be noisier.

Which Should You Choose?

**Choose composite if:** You want a natural wood look, are on a moderate budget, and want an eco-friendly option made from recycled materials.

**Choose PVC if:** You're building near water (pool, dock, marina), need maximum moisture resistance, want the best fire rating, or want the lightest-weight boards.

Price Comparison

Entry-level composite: $2.80-$4.20/sq ft (MoistureShield Vantage, Fiberon Concordia, Trex Enhance)

Mid-range composite: $4.20-$5.50/sq ft (Trex Select, TimberTech Terrain+, Fiberon Sanctuary)

Premium composite: $5.50-$8.50/sq ft (Trex Transcend, TimberTech Legacy, Deckorators Voyage)

Premium PVC: $7.00-$9.00/sq ft (Azek Vintage, Azek Landmark, Fiberon Paramount)

Remember that installed costs will be higher — typically $15-$30 per square foot installed including substructure, fasteners, and labor.
