Panda does not but there was a film very similar to panda film back in the day that did. It was called poly shield. They no longer exist. I actually spoke to the manufacturer of the easy grow film and they were the ones that told me their film is 97% thermal image blocking. They also told me if you put a 1" air gap under the film, between the wall and the film, you will get closer to 100% thermal image blocking. If you find an old Max yield magazine you will see the thermal imaging in there i believe.
