What is Composite Decking Made of?

Installed sand-coloured PVC deck boards.
Composite decking boards are made of a mixture of reclaimed materials that can include polyethylene plastic or PVC (polyvinyl chloride) mixed with wood fibre or other filler and chemical additives. The mixture is melted and then pushed through a former to create the lumber decking shape we know and love.

Different Types of Composite Boards

Physical Differences

There are four types of composite decking boards when it comes to how they physically look and function called board shoulders or board profiles. This refers to how the board looks from a side view or under view, and this affects the fastening options. These do not change the look of your deck, only how the decking is installed. Contact a contractor for the best options for your project.

Full Profile

Full profile boards are the most solid and sturdy with flat sides and bottom. It is the most solid feeling when standing on them and these act the most similar to regular wood decking.

Scalloped Profile

This decking has straight shoulders but two or more grooves running along the underside. These are made with less material which reduces the weight without sacrificing durability or strength.


A solid board not unlike the full profile board, but smaller and allows for easier top-down installation styles with some companies having hidden or colour-matching fastenings (these will be seen).
