Working on a project that we've installed Tyco attic heads and the GC has now gone in and added roughly several inches of spray on insulation. When I say roughly I mean roughly, the depth varies from 6" to 12" with no consistency what so ever. I've told them that most of the piping will have to be lowered to stay within the required clearances but I also think the insulation needs to be "shaved" to a smooth consistent finish, obviously that didn't go over so well. Since attic heads are considered extended coverage I think it's safe to assume they need to be installed per the requirements of NFPA as well, under a smooth flat surface. Am I missing something?
