Ampex panels have unique mushroom-shaped nubs which lock the PEX tubing firmly in place (staples and zip ties not needed). The 2′ x 4′ (610 x 1220mm) 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).

The combination of molding expanded polystyrene (EPS) insulation, one of the highest performing energy efficient insulation materials available today, with a High Impact Polystyrene (HIPS) film, makes for a strong and resilient Ampex panel. The panel combines rigid insulation, a vapour barrier and PEX tubing locking mechanism into a single solution that significantly reduces installation time.
