Pipe insulation for radiant tubing?

All of my radiant tubing between baseboards runs through the ceiling/walls of a currently unfinished (and unheated) basement. Should I wrap that tubing with the foam pipe wrap insulation to prevent heat loss? I assume the answer is yes, but just wondering about best practices, etc.

    Definitely insulate the home-runs to take control of your unwanted gains to spaces.

    There ARE times when a home-run loop can afford a margin of heating or semi-passive freeze protection, but this does not sound like one of those.

    On a radiant floor design I did for a performing arts center in Western MA, we specified Armaflex on the home-runs. Had we not done that, the interior would have been over-radiated by a factor of three and not at all comfortable and with no recourse.

    Code calls for min 3/4" wall neoprene or fiberglass pipe covering in unheated or unconditioned spaces.

    Basement temps

    I was thinking of doing this to, since my basement is unfinished and un-insulated. However, by insulating the pipes, will that cause temps to drop in the basement which can lead to frozen pipes? Or does code call for ALL water pipes to be insulated?
