FLOOR JOISTS - The thin (film) RetroHeat® floor heating element is designed to be installed in typical wood and/or metal floor joists. The joists must have a facing width no greater than 2-inches with a spacing between the joist strips of 12-, 16-, or 24-inches on center.
FLOOR SURFACE - The flooring may be any material with a total thermal insulation value of less than R-11 / RSI-2. This includes ceramic tile, hardwood, laminates and even carpet. Secondary materials may also be added to the floor at a later time. For specific information concerning the thermal insulation factor of the material being specified, contact the material manufacturer.
SURFACE FINISH - RetroHeat can be used to warm any type of finished floor surface. The total thermal insulation value of the subfloor and floor finish must not exceed R-11.
INSULATION - Only two types of insulation should be used with the RetroHeat system:

The design of the floor heating system must take into account that proper clearance from electrical fixtures, cabinetry, partition walls and other permanent features in maintained.
Permanent Features - RetroHeat heating panels must be installed so that they will not be covered, even in part, by partition walls or other structures that cross the floor. Heating panels that are covered by any structures may overheat.
Electrical Wiring - The wiring in the floor must be at least 2 inches from the heating panels with a barrier of insulation filling that space. This space may be horizontal along the joist space.
Surface Mounted Fixtures - Do not install the heating panels closer than 8 inches from the edges of any electrical boxes for surface mounted fixtures in the floor since surface mounted fixtures may have additional trim which extend far beyond the edges of the electrical boxes.
Recessed Fixtures - At least 2 inches of clearance must be maintained between the trim of recessed fixtures or outlets and the heating panels.
Pipes - Maintain a clearance of at least 2 inches between any pipes (metal or plastic) and the heating panels.
Heat Sources - A clearance of at least 8 inches must be maintained between other heat sources and the RetroHeat film heating panels.
End of Joist Cavities - Leave at least 6 inches of clearance at each end of each joist cavity to accommodate wiring and assembly.
