Styrofoam has a higher R value per inch than fibre glass.

Code is different for each local. In Alberta it's 5 in. off any frost wall.

Im assuming your not in Alberta though, since you would have froze to death long ago with only R-7 in the walls.

of course, it's best if you don't have water pipes in outside walls but if you must....
I'd use a high grade styrofoam, maybe the foilback stuff....not the cheap white stuff.
ALWAYS keep the pipes on the warm side of the vapour barrier!!!
If you can, keep the pipes exposed to the warm air in the house instead of drywalling over them. Anything to give your pipes the edge in those nippy winters.
