Noted a similar situation being constructed when our new house was being built. Before the drywall was installed, I noticed that the water pipes in the walls going to the outside bibs(faucets) were wrapped in insulation protecting them from the available heat inside the house! I fixed it right away. Now the insulation is all between the pipes and the outside, giving the pipes access to the heat inside the house through the drywall. I believe it is a much better setup.No other pipes in our house are on/in outside walls.Woody
