In this case, the pipes are not insulated. Water pipes are laid below the depth of freezing of the ground. In addition, the water in the plumbing is moving, which is an additional guarantee of non-freezing. But if you have extra money and time, cover the pipes with glass wool or something similar. There's a lot of insulation these days.
