Glad to hear i'm not the only one who likes foam for insulation. For hot water (hydronic) pipes, i wrap them with the cheap pipe foam, then run both pipes in the same 6" plastic tube, wrapping everything with fiberglas. An inch of dry insulation can perform as well as a YARD of soil, so the payoff is obvious :)
Here in central Mn it can be 20 below for weeks on end, and thru the judicious use of foam, (i mean burying sheets of the stuff above the pipe to block moisture and frost penetration)i've hardly ever had to dig more than a couple feet. Bear in mind, insulation only helps when it's kept dry, and many foams (like the squirt foam) WILL absorb water, turning them into pretty good frost conductors. Oops!
