  • Profile size: 59mm x 40mm x 3600mm

Comprised of the same material as NeoTimber’s decking boards, our premium composite joists boast all the same excellent properties. This joist is an ideal solution for low-lying projects whereby you are installing directly onto a solid base (such as concrete). Our NeoTimber® composite joist is a long-life, low-maintenance subframe option that is an excellent solution in aiding drainage, working hand-in-hand with our NeoTimber® composite deck boards. You can use our decking calculator to work out the exact number of joists required for your specific application, but as a general rule of thumb we recommend purchasing one joist for every square meter of decking.
