water supply in un-insulated wall

the half inch copper supply pipes for the bathroom run up the wall cavity of an older home that's not insulated. to compound the problem its the north wall and the coldest side in the house. thankfully there have not been any problems to date with freezing, but to be proactive i was thinking of pushing up some insulation around the pipes from the basement. would any type of insulation be good (foam board, attic, wall) and should i attempt to put some foam tube insulation around the pipes first.

thanks

One thing that probably kept those pipes from freezing in the past is hot air rising in that cavity from the basement.

I would definitely try to cover the pipes with the foam insulation. It might be a tough job especially if those pipes are fastened to a beam. The insulation would stop there leaving the top side of the pipes unprotected.

Insulation between the wall and the pipes is a good idea, insulating the entire stud space probably not such a good idea as it is heat from the home that now keeps the pipes from freezing.
