More About Our Recycled Plastic Joists

Any great Decking project starts with the frame. Making sure your joists are secure, installed correctly, and structurally sound is paramount for a long-lasting Deck project.

Cladco Recycled Plastic Joists are a high-quality, robust and durable Joist solution, available in black. These can be used with CompositePVC or Timber Decking Boards. 

Our Plastic Joists are manufactured from 100% recycled plastics, using state of the art technology. Post-consumer plastic is shredded down, melted and formed into moulds, creating high-quality and durable Joists.

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 maintaining, 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 wood-working 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.
