Everything You Need to Know About Composite Decking

What’s in Composite Decking?

The composite material used in Cladco’s Composite Decking is a wood and plastic mix. Roughly 50% wood, 40% recycled plastics and 10% glue and tints etc. it’s mixed together and then extruded to form either a hollow or solid decking board.

The benefits of mixing these 2 products groups are obvious, you end up with the durable, hard wearing, maintenance free elements of the plastic and the beauty, look and feel of the wood giving you a great looking product that will last for years and years.

Simple to clean and maintain

Our WPC decking is hard-wearing and easy to maintain. The composite material used in their construction means the boards do not rot, splinter, or warp like many traditional timber boards.

Also unlike many traditional timber boards our boards do not need to be regularly sealed, stained, painted or waterproofed. They are easily kept clean by sweeping and the occasional use of a jet hose.

  • Do not splinter, split, rot or warp
  • No need to regularly seal, stain or paint
  • Low water absorption rate, do not attract mould or fungus
  • Resistant to attack by insects

Our solid core boards offer a single anti-slip walking surface featuring narrow spaced grooves. They offer greater strength and better sound absorption. Unlike our hollow boards their ends do not need to be capped.


Our hollow core boards feature a lightweight honeycomb construction and are reversible with narrow spaced grooves on one side and wider spaced grooves on the other. These boards offer two different anti-slip walking surfaces.


Our woodgrain boards feature an attractive woodgrain pattern that gives the appearance of natural wood. Constructed with a honeycomb core featuring a 5 hole design for increased strength and durability.
