There could be. If the film is shiny, the foam may not adhere well to it. I would test it out to check its adhesion first. Also, when you spray foam to a film, it has a tendency to cause the film to draw away from the substrate forming a bubble under it. You need to fasten the film down well to prevent this from happening.

Good question. I don't have any data on the use of sprayfoam and radiant barriers and their effective use together. Any info out there that you could share?
