Ampex Insulated Panel for Hydronic Radiant Heating
Ampex® is an under-concrete insulated PEX panel for hydronic radiant heating.
The combination of moulding expanded polystyrene (EPS) insulation, one of the highest performing energy efficient insulation materials available today, with High Impact Polystyrene (HIPS) film, makes for a strong and resilient PEX panel. The panel combines rigid insulation, a vapor barrier and PEX tubing locking mechanism into a single product that significantly reduces installation time.
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 large, four-sided interlocking shiplap connector system makes for quick, easy and secure installation while maintaining continuity of the vapor barrier eliminating the need for a dedicated 6 mil. Polyethylene (unless specifically required by local building code).
The 2’x4’ panels are placed on compacted stone/gravel. Ampex panels employ unique “mushroom” shaped nubs which lock PEX tubing firmly in place (staples and zip ties not needed). PEX tubing is easily inserted into the panels simply by walking in the tube. 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 Ampex® insulated panel is available across residential (30 psi), commercial (45 psi) and commercial/ industrial (60 psi) applications. The residential panel is made using Type II EPS (1.5 lb/ft3 density) with R-values of R10, R12, R14 and R16. The commercial panel is manufactured using Type IX EPS (2.0 lb/ft3 density) with R-values of R11, R13, R14 and R16. The unique patented design of the nubs will accept PEX tube sizes of 1/2”, 3/8”, 5/8”, 3/4” and one of the very few insulated radiant PEX panels on the market to accept 1” PEX tubing (commonly used in commercial applications).
The Ampex panel is designed to save time and labor cost with the installation and perform more energy efficiently once installed.
Benefits of the Ampex Panel:
Quick and easy walk-in installation of the PEX tubing
No staples or zip ties required and eliminates working at 45 degree angles
Nub height allows for tubing of multiple diameters
Consistent grid pattern allows for uniform heat transfer
Height of the nubs protects the tubing when the panel is walked upon
Easy, manageable panel size reduces the waste at site
Ampex Radiant Heating Applications:
Heating system for basements and other living areas viz. kitchen, bathroom etc.
Snow and ice melt applications for driveways & walkways
Heated floors for outdoor patios.
Automobile establishments including garages, car washes and dealerships
Agricultural applications viz. farms and barns
Workshops and factories
