Ra-flect™ Radiant Barrier Under Floor Installation:


Our Ra-flect™ Radiant Barrier can be used under an elevated floor to cut down on heat gain or heat loss through the flooring.

Installation Tips:

  • Perforated Ra-flect™ Radiant Barrier is recommended for this job
  • Unroll the Ra-flect™ Radiant Barrier and staple to bottom of floor joists
  • Overlap each run by about 2 inches
  • Tape seams to reduce air infiltration
  • Widths: 48”, 26”, 24”, 18”, 16”

Ra-flect™ Radiant Barrier in Radiant Heat Flooring:


Radiant heat floors are becoming very popular, however, they have a tendency to loose their heat to the space below.  Our Ra-flect™ Radiant Barrier will increase the efficiency of these radiant floors by reflecting the majority of this heat back into the conditioned space.

Installation Tips

  • Perforated Ra-flect™ Radiant Barrier is recommended for this job
  • Ra-flect™ Radiant Barrier should be sized in width to match your floor joist spacing
  • Install Radiant Barrier directly beneath radiant heat tubing
  • Staple in place or allow the material to rest on top of the floor insulation
  • Add conventional insulation to the underside of the Radiant Barrier
  • Widths for dimensional lumber - 26” (24” o.c.) or 18” (16” o.c.)
  • Widths for manufactured floor joists - 24” (24” o.c.) or 16” (16” o.c.)

Ra-flect™ Radiant Barrier Between Radiant Heated Floors:


When used in the floor between two radiant heated floors, our Ra-flect™ Radiant Barrier helps direct the heat to the zone in which it is needed.

Installation Tips

  • Perforated Ra-flect™ Radiant Barrier is recommended for this job
  • Ra-flect™ Radiant Barrier should be sized in width to match your floor joist spacing
  • Install Radiant Barrier directly beneath radiant heat tubing
  • Staple in place
  • Typically, conventional insulation is not used, except for sound control
  • Widths for dimensional lumber - 26” (24” o.c.) or 18” (16” o.c.)
  • Widths for manufactured floor joists - 24” (24” o.c.) or 16” (16” o.c.)

Note: To use radiant barrier under a concrete slab, you need to use one of our Foil-Bubble products.
