   The stuff is faced with f/g and it can be itchy, like working with insulation.  Some have said it is heavier per sheet, but I haven't done enough with it to say one way or another. 

   While it may be less likely to support mold growth in a moist enviornment, I wouldn't substitute it in places where CBU or a membrane under tile are warranted.

   It's exterior gypsum sheating in a white color. Wear a good respirator when installing for the fiberglass will fly all over. The entire board has to be skim coated as the material is not perfectly flat as regular gypsum. The screws puncture the material and do not hold it well.

   Suggest using National Gypsum XP Drywall..purple colored which is anti mold and has paper on it.

   I think you will find that it is only good as long as it stays in full sheets.  Once you cut it, the gypsum core is exposed and that will support mold, so all cut edges have to be sealed.

   If it is only being used for wall inthe dry areas of the room, it would be ok.  Green board would be a good choice too.  But neither is a good choice for a wet area like a tub or shower enclosure.

   what I would use is blue board or green board, wonderboard or creteboard. or anyother board used for kitchens and baths. forget about the paperless drywall. We all know that mold and mildew is a product of moisture + warmth + darkness. the key to preventing mold and mildew is seal properly the surface and keep wiped dry.
