APPLICATION OF INFLOORBOARD™ TO WALLS OR CEILING
Infloorboard™ may be installed on walls or ceilings as extra heat output areas
when the floors cannot provide all the necessary heat. Radiant walls and ceilings
may also be used to provide all the heat of a room in certain circumstances when
properly designed. The heat output of radiant walls and ceilings is different
from floors, due to differences in the strength of the convective component of
the heat which is stronger in radiant floor heating than in walls or ceilings.
However, since walls and ceilings are typically covered only with the relatively
low r-value of 1/2” of sheet rock, and acceptable surface temperatures are high-
er, the heat output of these systems can be quite substantial. It is very important
not to overheat sheetrock or discoloration or damage may occur. For design pur-
poses, use chart C-1 but correct the output in BTU’s downward 5% for walls
and 10% for ceilings. This is because the convective component of the heat out-
put is lower in wall and ceiling radiant heating systems.
Infloorboard™ wall and ceiling systems shall be installed as follows:
Infloorboard™ shall be installed square to framing, screwed to studs, rafters
and/or blocking with as many joints as possible screwed securely to the framing.
Infloorboard™ shall be secured to framing on both sides of the grooves on every
board. Layout of all pieces shall be started by securing a corner to allow for
proper alignment. 6” lengths of tubing shall be temporarily placed in the grooves
lapping 3” into each board to help align the grooves of the boards during instal-
lation. Once all boards are installed, all grooves shall be cleaned out with a vacu-
um just prior to tubing installation. Tubing shall be snapped into the groove and
routed to manifold per the plan. A 1” minimum tubing clearance from tubing
shall be maintained for all nailing. Add steel plate protectors over tubing where
tubing crosses studs. Water temperatures shall not exceed 120F° supply water
temperatures when Infloorboard™ is installed under plaster or sheetrock.
