Georgia-Pacific has product called DensArmor, which is gypsum board with
a fiberglass (instead of paper) facing. The ads say mold is less likely
to grow. The 5/8" x 4'x8' sheet costs US$19 here in Kansas City, and
only three places carry it. For comparison, regular 5/8 sheetrock at
Lowe's is US$8.64 right now. I've never used the new stuff, but I
filled-out the form for the samples, and I got a box full of them today.
So, is it worth the ten extra bucks?
Check the John Bridge tile forum. If it's the stuff I think it is, it
got trashed, literally. That was in tile installations. If you just
need it for regular drywall work, using mildew inhibiting paint will
give you the protection you need.
