RetroPanel is a perfect retrofit product for applications where comfort, efficiency, system height, and performance is key. It uses the combination of metal on the surface, with high thermal conductivity and built-in insulation underneath, to maximize the heat output at low water temperatures. The metal surface also promotes an even temperature distribution across the floor, minimizing cold spots. The low thermal mass allows for a quick response to Retrofit system for existing applications changing load requirements. Retro Panel is unmatched in its ability to optimize system efficiency.
