amvic Ampex AMPEX3515F Radiant Floor Heating Panel, Insulated, Polystyrene

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 vapor barrier and PEX tubing locking mechanism into a single solution that significantly reduces installation time. The Ampex panels have unique "mushroom" shaped nubs which locks the PEX tubing firmly in place. The 2 x 4 ft 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 encasing the tubing, nubs and any steel reinforcement.
