Wood was the decking material of choice until the late 1990s. At that point, composite decking was introduced and became an attractive alternative to wood due to its low maintenance and high durability. But if it’s not made of wood, what is composite decking made of? Read on to learn from the experts.

Wood or non-wood composite decks
A composite deck is made of either wood flour, recycled post-industrial material, or wood fibres such as polyethylene or hardwood. There are also non-wood composite decks that are created with a fibre-like inner structure. These great decks offer amazing benefits such as high durability, low maintenance, mold/slip-resistant – truly a homeowner’s dream.
Mix of plastic and wood
Composite decking is a mixture of plastic and wood fibers held together with a bonding agent. The ingredients are heated, mixed together, and then cooled.
Some composite decking is made of recycled material, making it a greener choice.

Resin and wood
Composite decking is an advanced and reliable decking material made of resin and wood. Manufacturers use wood pieces to give the panels the appearance of wood, while at the same time, the resin holds the wood together to protect the deck from weather damage. Composite decking will last longer than other popular decking options, and will never need to be resealed or stained.

Varies for each brand
In recent years, composite decking materials have taken the deck building world by storm. The exact composition for composite decking materials varies for each brand, however, the primary ingredients are plastic (polypropylene or polyethylene) and wood (sawdust, wood chips, or wood fiber pieces). Typically, the plastic and wood materials used in composite decking are sourced from recycled materials, which make composite decking a more ecofriendly option for consumers. When compared to traditional alternatives, composite decking is more resistant to rot, warping, and splintering. Composite decking is a smart choice for consumers looking for a lower maintenance decking material.
