I bought a new place with popcorn ceilings. I want to remove the ugly popcorn effect and i got instructions on how to do it. however, i was told that there are heating coils underneath the drywall in the ceiling. Does any one know what the purpose of popcorn ceiling is, other than for decorative (ughhhh) purposes? In other words, if I remove the popcorn would it damage the heating coils in any way? thanks you.
