Default Wrapping outdoor faucets (hose bibs)

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.
