Durock in lieu of Sheetrock
I’m wondering if Durock can be used instead of Sheetrock? Many of the exterior walls will have wood paneling on top of said Durock. Is Durock an acceptable alternative to Sheetrock if it’s seams are taped and plaster venner skimmed? I can’t seem to find any info on if it is airtight/ what its vapor perm is. The reason I am considering Durock instead of Sheetrock is the structure is in the hot humid flood prone south where moisture and mold is a big factor.
Any insight would be great!
