Appendix E Climate Trak
C.1 Overview
Climate Traks and Heat Transfer Plates are designed for retrofit applications or in applications where the
buildup above the subfloor is a concern. These types of applications are not the most efficient kind of radiant
heating systems but deliver the comfort of having warm floors and full radiant heating throughout the house.
Both methods utilize ViegaPEX Barrier tubing and attach directly to the underside of the subfloor. This is a
fast, lightweight application to install and provides the comfort of radiant heat the homeowner is looking for.
Climate Trak:
1. Heavier aluminum than the Heat Transfer Plates
2. Fastest installation time (does not require Groove Tube)
3. Easiest to install (Traks and tubing are installed separately, so there is no struggling with the tubing while
the fastening is being done)
4. Predrilled holes for ease of fastening with screws
5. Comes in 4' or 8' long Traks that also help with installation time
6. Snap-in groove for tubing maximizes contact between the aluminum and the PEX tubing for efficient
heat transfer
Heat Transfer Plates:
1. Made from thinner, more flexible aluminum than the Climate Traks
2. Comes in 19" long by 5" wide plates
3. Requires a small bead of Groove Tube down the channel where the tubing is run right before installation

Be sure to check with local building codes to
ensure no structural damage will occur due
to drilling the joists. Use 1¼" holes at min. 3"
from the suboor to avoid oor nails. Centered
holes would be ideal for structural strength.

R-19 Insulation:
Use a Foil Face or Radiant Barrier
to keep a 1" to 2" air gap between
the insulation and the Traks.
Refer to local code for insulation
requirements.
Climate Trak: 3½"W x 48" or 96"L
have a 1" gap between Climate
Traks, install 1½" off the joist
