Master Lock RADIANT PANEL SYSTEM - Manual (Page 4)

5A. INSTALLATION INSTRUCTIONS
5A.3 Installation of the Panel
The sub-floor must be smooth, clean and level. Surface irregularities should not exceed more
than 0.02" per foot. The Roth Radiant Panel System
®
should be secured to the subfloor with
countersunk screws or a foam board compatible adhesive. Apply the adhesive according to the
manufacturer’s instructions.
Start the installation by laying the radius panel first. If you need an extra track you can start with a
transition panel. A strip of plywood can be installed on the perimeter for tack strip when carpet is
the finished floor material. It is important to plan the installation in advance to be sure that you
have the correct number of tracks when installing the tubing. Transition and radius panels can
be installed upside down as filler pieces.
When securing the panels to a wood subfloor, we recommend using at least eight (8) countersunk screws spaced 12” (30 cm)
apart and 6” (15 cm) from the edges. When installing over concrete, you can use countersunk concrete fasteners in the same
pattern. Be aware that floor conditions may require use of additional fasteners. The panels can also be secured with latex base
adhesives compatible with foam board products. These are applied with either a caulking gun or notched trowel. Follow the
manufacturer’s instructions for application. Curing time can vary widely between brands of adhesive and with the temperature
and humidity conditions at the time of installation.
