About Ampex: Insulated Radiant Floor Heating Panel

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.

Ampex: Insulated Radiant Floor Heating Panel
Four sided interlocking shiplap connectors
HIPS film acts as a vapor barrier and adds durability
Bridge connectors enable better heat distribution
Mushroom nubs firmly locks the tubing in place
Range of R-values and compressive strengths

The innovative patented panel design ensures that the tubing is completely encased in concrete and not pushed to the bottom of the panel through the use of bridge connectors. The larger contact area between the tubing and the concrete allows for increased heat transfer reducing the response time of the system and helping achieve desired temperatures faster.

The Ampex 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).

Ampex Panel Benefits

Improved Thermal Comfort

Improved Thermal Comfort

Consistent grid pattern of the panel allows for uniform heat distribution.

Durable Installation

Durable Installation

The nub height accommodates multiple tube sizes and protects the tubing from damage when the panel is walked upon by other trades.

Reduces Waste at Site

Reduces Waste at Site

Light and manageable panel size reduces waste due to damage on site.

Quick and Easy Installation

Quick and Easy Installation

Quick and easy walk-in installation of PEX tubing without the need for staples and zip ties and completely eliminating the strain of working at 45 degree angles.

Built-In Vapor Barrier

Built-In Vapor Barrier

The large, four-sided interlocking shiplap connector system makes for a quick, easy and secure installation while maintaining the continuity of the vapor barrier and eliminating the need for a dedicated 6 mil. polyethylene (unless specifically required by local building code).
