Accordingly, can expanding foam be used around heating pipes?
Don't use spray foam such as Great Stuff around heat sources: it will melt and produce toxic fumes. BTW, the reason the holes are so big is probably because there used to be three-inch pipes there.
Beside above, can you grout around copper pipes? The answer is that tile grout seems to be very inert and does not normally corrode copper pipes.
Subsequently, question is, is spray foam corrosive to copper?
The chemical reaction to the foam as it expands will react with copper. The EPA and Clean Water ACT strictly prohibit this above the Mason Dixon Line as of 1994, March. Any Plumber or Homeowner who uses this type of insulation aroung copper plumbing without safeguards can, and will be fined by the EPA.
Where should you not use expanding foam?
Spray Foam Around Windows and Doors is A-Ok But it can actually push the jamb inward, making them impossible to open. Avoid this by using minimal expanding foam. It's formulated to fill the space around windows and doors without excess expansion. Look for cans labeled for use on windows and doors.
