When building an incubator out of styrofoam box (I made a box with EXTRUDED polystyrene, those pink insulation sheets made into a box), can I tape the heat tape to the foam directly? Or do I need to back it with something like plexiglass?
I see a lot of people here just tape the flexwatt inside the styrofoam box, heat tape directly touching styrofoam, so I would presume that it is ok to do so, but on an arboreal snake forum they cautioned against having flexwatt on styrofoam due to outgassing or something.
