A sturdy base is crucial for any quality decking build. Properly installed, structurally sound, and secure joists are essential for long-lasting decking boards.
Our plastic joists are made from 100% recycled end-user plastics, for a robust and high-quality decking joist. These black joists can be installed underneath Nordeck, Millboard®, timber or composite decking boards.

When your goods are delivered these are sometimes delivered on a pallet with the necessary
associated packaging to ensure they arrive with you in the best possible condition. We view the pallet and
packaging as necessary for the protection of the goods and therefore will be a part of what is delivered to you.
It is your responsibility to dispose of these items in a responsible manner when appropriate.
Our recycled plastic joists have a 20-year warranty to give you peace of mind that your decking boards are built on a solid and long-lasting foundation.
Where can Cladco plastic joists be installed?
They can be installed on various surfaces, including grass, concrete, and uneven terrain.
Why is it important to double joist and use two clips at adjoining boards?
When our Signature composite decking boards expand and contract, they must be securely fastened to minimise movement. A single joist may not provide sufficient surface area for the ends of two boards to be properly anchored. Using double joists at adjoining points ensures each board end is attached to a joist, increasing the stability of your project. Adjoining boards should never share the same clip, and should be secured using two clips per board end.
This method will improve the structural integrity of your decking; especially in high-stress areas like the ends, where foot traffic, weathering and material contraction or expansion increase the strain on your decking.
Adhering to these guidelines will help ensure proper installation and longevity of your Composite Decking. Failure to follow these guidelines will invalidate the product warranty.
