 Re: Cement Board, Hardiebacker, Durock... Which one?
Agreed,
Hardi does not specify in any of their literature that it is not suitable for exterior use...nor does it say that it is; merely states that it is suitable for all wet applications.
In any case, nearly every outdoor island and grill enclosure company uses Hardi (don't know why). With their experience with siding, I would have no problems using their board outdoors.
All things considered, Hardi, Durock, Wonderboard will all do the job very well. Use whichever is least expensive or more readily available.
One last point about the Hardi - be careful using the 1/4" product, it can break easily.....the only downside I can think of, probably inherent to most 1/4" sheet goods.
