Hello everyone! I have been lurking around for a bit and been finding conflicting info on this subject so I figured I'd get confirmation. I am attempting to build a stand up shower and would like to use Hardi Hydrodefense for the walls and ceiling of the shower. I would also be using a gold bond purple xp for the remaining walls and a kerdiboard pan with kerdi waterproof on top of the hardi for extra defense. I also may put on redguard as well just to bulletproof things. My questions are:
1. I've read conflicting info about redguard and thinset not playing nice on hardi with tile. Is that true?
2. My side wall is a concrete block wall in the basement. Currently the only insulation is around the header. Should I put 1inch rigid behind the studs and roll insulation between studs topped with a plastic sheet for vapor barrier? I've also seen conflicting info about putting a vapor barrier behind hardi.
3. Should there have been insulation behind this wall since it is a 95% finished basement along the foundation in Michigan? It gets down to 50-55 in the winter. It is a walkout raised ranch and I feel the didn't insulate the walls when they finished it.
Sorry for the long winded question. This forum and its members are amazing and I'm learning alot! Thanks for all the work you guys do!
