Infrared is light of a long wavelength. Like light, some materials
block it, some reflect it, and some absorb it. So it really depends on
the material and the thickness. But if you have a heat lamp or strong
infrared source it is pretty easy to determine if the rays are getting
through or not by simply seeing if you can feel the heat on the other
side or not.

I doubt that you want anything between the infrared heat emitter and
your skin because it would block the infrared rays and defeat the
whole purpose of the therapy. The rays should penetrate the skin for
deep heating. Of course, you don't want to burn yourself either.
Don't know exactly how you control that. It depends on the wattage of
the bulb, the area being heated and the distance of the bulb from the
skin (which would spread out the area being heated by the bulb).
