Is WPC Decking Any Good: Choose WPC Decking Or Composite Decking?

Installing a new deck is an exciting project that adds beauty and function to your outdoor space. When choosing decking materials, WPC and composite decking are two of the most popular non timber options, that while both are composite materials, have distinct differences. This guide looks at the pros and cons of WPC products vs composite to help you determine which is better for your new decking floor.

Before we dive into the detail, we’ve got a range of other decking articles you may find useful here on the site, such as types of plastic decking, and the pros and cons of hollow vs solid composite decking.

What is WPC Decking?

WPC stands for “wood plastic composite.” WPC decking is made from a mixture of recycled plastic and wood particles or fibers. The composition is typically around 60% recycled plastic and 40% wood.

The wood fibers are usually waste materials from other wood processing operations. The recycled plastic often comes from items like milk jugs, carrier bags, and bottles.

Benefits Of WPC Decking

  • Low maintenance – Requires less frequent staining or sealing than natural wood
  • Durable – Stands up well to weather, moisture, rot, and insect damage. Unlike traditional wood decking, it does not absorb water.
  • Stain resistant – The plastic composition resists absorbing stains
  • Consistent quality – Maintains consistency from board to board. 
  • Eco-friendly – Made from recycled plastic and wood wastes
  • Wood look – Often mimics the color and grain patterns of natural wood but with no need to sand.
  • Affordable – Comparable to or lower cost than natural wood decking

Potential Disadvantages Of WPC Decking

  • Can fade to gray tones when exposed to intense or prolonged sun
  • Limited color options compared to natural wood varieties
  • May be more prone to mold and mildew growth than composite
  • Not recommended for structural parts of the deck like support joists
  • Can develop small surface cracks over time

What is Composite Decking?

Composite decking is also made from a mixture of wood fibers and recycled plastic. But composite typically contains a higher percentage of wood (60-70%) compared to WPC decking.

In addition to wood fibers and plastic, composite decking also incorporates other additives like binding agents and UV blockers to enhance durability.

Benefits of Opting for Composite Decking

  • Low maintenance like WPC, doesn’t require frequent staining or sealing. This results in shorter cleaning and maintenance times.
  • Durable and long-lasting – Withstands weathering better than natural wood
  • Resists fading – UV blockers help maintain consistent color over time
  • Realistic wood look – Mimics patterns and colors of natural wood more closely
  • Customizable – Wider variety of color and finish options
  • Stain resistant – Doesn’t easily absorb spills and stains

Potential Drawbacks of Composite Decking

  • Generally a more expensive option than WPC
  • Can experience color fading over time when exposed to constant sun
  • Mold and mildew can grow on surface if not cleaned
  • May be more prone to damage from impact compared to WPC
  • Can’t be worked with traditional woodworking tools
