Technical Specifications

Insulation — The only types of insulation permitted with the
Calorique Warm Floors System are:
· Unfaced fiberglass batt insulation
· Rigid insulation panels
DESIGN CLEARANCES
When designing the heating system, care must be taken to ensure that
proper clearance is maintained from electrical fixtures, cabinetry, par-
tition walls and other permanent features.
Permanent Features — Calorique 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 which are covered
by any structures may overheat.
Wiring — Electrical wiring, in the floor must be at least 2 inches / 50
mm away from the heating panels with a barrier of insulation filling
that space. This space may be horizontally along the joist space.
Surface Mounted Fixtures — Do not install Calorique heating pan-
els closer than 8 inches / 200 mm 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 / 50 mm of clearance must
be maintained between the trim of recessed fixtures or outlets and the
Calorique heating panels.
Heat Sources — At least 8 inches / 200 mm of clearance must be
maintained between heat sources and the Calorique heating
panels.
Pipes — At least 2 inches / 50 mm of clearance must be maintained
between any pipes (metal or plastic) and the Calorique heating panels.
End of Joist Cavities — Leave at least 6 inches / 150 mm of clear-
ance at each end of each joist cavity to accommodate wiring and
assembly.
DESIGN CRITERIA

Use only non-com-
bustible insulation.

Do not use cellulose
insulation of any
kind.

Do not use metal foil
faced insulation or
metallic vapor barri-
ers.

If a vapor barrier is
required, install it
normally to the upper
sides of the joists.
This installation may
be done before or
after the heating
panels have been
attached or wired,
depending on access.
NOTE
When the Warm Floors System is used as a primary heating system,
all walls, ceilings and floors that separate a heated space from an
unheated space or the out-of-doors must be insulated to ensure
proper operation of the system.
