Composite Material

Strictly speaking, composite materials are any new material made up of two or more components. In the decking industry composite is also often used to refer to any non-wood decking material, even if they are only made from a single component. There is a wide range of composite decking materials available on the market. The most common composite materials include a mixture of plastic with another filler material. Other deck boards are a full plastic or mineral composite.

Popular decking composites on the market today often include a wood filler. Wood filler makes the composite boards cheaper, but also suffers from many of the faults found in traditional lumber decks. When your deck boards are made with a wood filler product, your risk for rot, decay, and mildew increase as moisture can seep in. Most decking products don’t cover these moisture-related faults in their warranties because they know it is a common point of failure in wood filler composite deck boards.
