These panels have unique “mushroom” shaped nubs which locks the PEX tubing firmly in place (staples and zip ties not needed). The 2’x4’ (610x1220mm) panels are placed on compacted stone/gravel. PEX tubing is then easily inserted into the panels simply by walking in the tubing. Concrete is poured on top of the panel to the required thickness (as per local code) encasing the tubing, nubs and any steel reinforcement (optional – rebar or welded wire mesh).
