Fire Caulk is very very expensive stuff, and a joke I think. We have had this law inforced hard here in North Dakota. We had to fire caulk everything, closet collars ever single pipe penetration and also our floor drains. This ran about $1000 in caulk we did not expect. It is kind of a joke. We ran cast iron floor drain, what is the need for caulk on this? Wood floors, gees the fire will burn the floor first.
