Product Description

Cladco Recycled Plastic Joists are a durable and eco-friendly solution for constructing a solid foundation for any Decking project. These high-quality Joists require minimal maintenance and can be effortlessly tailored to the desired length during installation.

The foundation of every successful Decking project is the frame, and it’s crucial to ensure that the joists are firmly secured, accurately installed, and structurally sound for a durable outcome.

Cladco offers an excellent solution with their Recycled Plastic Joists, which are available in black and designed to withstand wear and tear when used with Composite, PVC, or Timber Decking Boards.

Their Joists are made using advanced technology and 100% recycled plastic material sourced from post-consumer sources.


  • Length: 3.6m
  • Width: 100mm
  • Height: 50mm
  • Colour: Black

Plastic Joists are an innovative and versatile alternative to timber joists and can support your Decking project for many years to come, without the need for annual maintenance. Unlike wood, plastic lumber does not require regular treating or maintenance, and should not splinter or rot. The lack of maintenance helps to reduce future costs for your Decking project.

Cladco Recycled Plastic Joists come with a 10-year warranty, along with a range of other beneficial properties, including:

  • Made using 100% recycled plastic – recycled and recyclable
  • Superior strength compared to timber
  • Manufactured in the UK
  • An environmentally friendly and long-term solution to using timber
  • Can be used on concrete, grass or uneven ground
  • For use with PVC, Composite Decking and Timber Decking
  • Should not rot or splinter
  • Maintenance free


Recycled Plastic Joists are easy to install and can be cut to size using traditional woodworking tools, so no matter your Decking design, these Joists should be able to fit perfectly.

Cladco Plastic Joists require support every 1m for the structure of the joist itself. When installing Composite Decking onto Plastic Joists, we advise 400mm centres. For using Plastic Joists with PVC Decking Boards, we advise 300mm centres.
