What is Composite Decking?

Composite decking is anything made of two or more materials that are blended or fused together to form the structure of the deck board. All composite decking is made of a combination of wood fibres and plastic that together create a robust and durable decking material. It is also often referred to as wood polymer composite decking, recycled decking, plastic composite decking, or synthetic decking.
Capped wood-plastic composite decking uses a combination of wood fibre & plastic resins that are combined under heat and pressure to form the core of the deck board.

Capped-polymer decking uses a blend of resins and other performance additives without any organic materials in the core of the board. Capped-polymer decking is lighter; easy to install with no pre-drilling required. It is about 30% cooler than a wood-plastic composite deck of the same colour due to lower thermal mass & has no organic material in it, so it is virtually impervious to moisture over extended periods of time.

Composite Decks Require Little Maintenance

One of the greatest benefits for composite decking, as explained by homeowners, is the fact that it’s far easier to clean and maintain than wood decking. First composite decking is more resistant to weather, pests, mold, and other natural sources of decay and colour fading. It’s certainly easier to clean than standard wood decking so no need for yearly power washing, sanding and staining. To get your composite deck looking fresh and clean all you need is a soap and water.
The bonus is the material doesn’t rot, crack, splinter, or deteriorate with time, making this decking material a great choice if you have small children or pets.
