  For it to be "infrared" I would expect the panel to be insulated from heat loss to the surrounding air. This is how infrared cooling works, but the principle should still apply (actually more!) for heating panels.
  It's unusual thinking of heating the air as "loss," because normally we would say that any lost heat will still heat the room, but infrared heating is used precisely because heating the air is less efficient (ie less of the heat reaches human skin, which is all that really matters!)
