Pex will still freeeze but it is less likely to burst. The solutuion

_What about freeze-break resistance?_

"Vanex PEX will stretch slightly to accommodate the expansion of
frozen water, then return to its original size when the water thaws.
This memory is a feature of cross-linked material, giving it
thermo-elastic behavior. Although freeze-break resistant, no pipe is
freeze-break proof under all circumstances. Insulation of plumbing
pipes as instructed by local codes is still required."

Note, do NOT wrap the insulation all around the pipe, instead place
the insulation between the pipe and the cold wall, leaving the pipe
exposed to the warm side.
