Warmfloor's selection of T-J.B.F.P-I-P panel is
a standard 2400 x 600mm tongued and grooved flooring
panel with a serpentine channel formed into the
underside into which 10mm diameter high-quality
PEX barrier heating pipe is pressed. The whole
of the underside of the panel is covered with
aluminium foil and the top surface is permanently
printed to show the position of the pipe within
the panel.
The addition of the heating pipe transforms
the plain floor panel into an underfloor
heating module. Locating the pipe wholly
within the panel ensures higher thermal
performance in a timber floor than any other
form of UFH and performance which does not
diminish during the life of the panel.
Panels are usually
22mm thick moisture-resistant chipboard.
The pipe is arranged in any of three patterns,
with the pipe running the full length,
three-quarters or half the length of the
panel. The plain end can be trimmed to
the centreline of the relevant joist/batten..
The 22mm chipboard panels have been fully tested for use with joist centres up to 450mm. (Confirmed by tests conducted at TRADA and BBA).
The aluminium foil has two functions. Firstly, it is highly reflective and this minimises radiant heat loss to the underside. Secondly, it acts as a partial fin to the pipe and assists heat transfer from the pipe.

Principal heating panels are available with straight parallel channels at either 200 or 250mm centres. You choose which you need according to the heat required.
Unfoiled return panels suit these spacings. They have three rows of return loops, which can be easily separated using a knife. Unfoiled transit panels carry Flow and Return pipework through common areas such as hallways and around corners and into the manifold. The absence of foil automatically insulates the pipe and reduces the heat transfer in areas where it is necessary to prevent the floor becoming too warm.

Panels can be interconnected from above with the pipe tails set into small notches. The Flow/Return is covered with a section of plain panel.
Panels can be floated on rigid insulation with the pipe and connectors set in channels in the top of the insulation. (Pre-grooved insulation is available to make this easy).
