Composite vs. PVC Decking

What They Are Made Of

Capped composite decking has a core made from wood fiber and recycled polymer, wrapped in a protective outer shell — the cap. The cap resists moisture, fading and staining while the core provides structural rigidity and a more natural feel underfoot.

Advanced PVC decking is entirely synthetic — no wood fiber. It is sometimes called cellular PVC because it has a dense outer surface and a lighter, closed-cell core. Because it contains no organic material, PVC cannot rot, will not absorb moisture and is naturally resistant to mold and mildew.

Key Differences

Which Is Right for You?

Capped composite is an excellent choice for most Connecticut residential decks — it balances appearance, durability and cost. PVC is the right choice when moisture is the primary concern — pool decks, heavily shaded properties, coastal locations and applications where the deck is frequently wet.

The best way to compare composite and PVC is to see and touch actual samples in the light conditions and surroundings of your property. A deck evaluation provides project-specific material guidance based on your deck, your property and your preferences.
