5A. INTRODUCTION The Roth Radiant Panel System® was developed for the wood frame 
houses of the North American and Scandinavian markets. It was 
designed for easy installation over any new or existing sub-floor, 
wood or concrete, and for use with many different floor coverings, 
such as carpet, tile or hardwood. This is done without the structural 
changes needed to accommodate the additional load of lightweight 
concrete and with minimal effects to the finished floor height. It is 
ideal for retrofit systems, but it’s also great for new construction when 
you don’t want the weight, expense or water problems of lightweight 
concrete. The efficient design of the system, heavy gauge, full-face 
aluminum sheet on top and EPS insulating foam on the bottom, 
focuses the heat exactly where you want it – directly under the 
finished floor – so that the system can run at the lowest temperature 
possible. The quick recovery time makes this system one of the few 
times that temperature setback makes sense in radiant floor heating. 
These are just some of the advantages you will receive from the 
intelligent design and high quality of the Roth Radiant Panel System®.
