Features, Benefits and Technical Details

What’s in the 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


Easy to build

Quickly build your deck. Boards can be worked with normal woodworking tools and are easily fastened to a suitable supporting joist substructure with our stainless steel screw and nylon T-Clip system.

The Installation page and our downloadable PDF brochure provides general information on how to build a deck using our WPC decking boards . Further information can be obtained by calling our Customer Service Team on 01837 659 901



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 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.

Both types of board are a high quality product manufactured to exacting specifications. Further data on their technical properties (e.g. strength, stiffness and water absorption) can be obtained by contacting our Customer Service Team.
