All good info, but none addresses my original question of WHY it helps to
wrap faucets.

Anyone have any ideas??

It slows the transfer of heat. Metal is a great conductor of heat, which means
that the cold outside will follow the valve/pipe into the wall. By wrapping the
facuet, you put a thermal break in place which in tun keeps the pipe and valve
warmer. In most cases, it only takes a few degrees to keep things above freezing
at the valve.

And also since the OP lives in Texas...just cracking the valve open
enough to let the water slowly dribble out over night for the few
times that temps go below the freezing mark would work. This may not
be practical depending on location of the valves vis a vis the walks,
shrubs, foot traffic, etc..
