Recycled materials can make a deck last longer and need less upkeep. Here is how the main options compare, and where wood still belongs.
Recycled-content composite
Made from wood fiber and recycled plastic, capped composite boards resist rot, stains and splinters. They are the most popular low-maintenance choice for walking surfaces.
PVC decking
Fully synthetic boards that do not absorb water. Light and cool underfoot, good for wet or shaded decks.
Recycled plastic lumber
Used for benches, planters and trim pieces. It is very rot-resistant but not usually rated for structural framing.
Metal framing and railings
Aluminum and steel railings and some framing systems are durable and recyclable. Metal framing is less common on homes but very long-lasting.
Comparison
| Material | Rot resistance | Structural use | Upkeep |
|---|---|---|---|
| Composite | High | Decking only | Wash yearly |
| PVC | Very high | Decking only | Wash yearly |
| Recycled plastic lumber | Very high | Non-structural | Minimal |
| Aluminum | Does not rot | Railings, some framing | Minimal |
The framing is still wood
Most decks still sit on treated wood framing. Joist tape, flashed ledgers and raised post bases are what keep that framing from rotting under a recycled surface.
