Final Advice before I start please.
Ok, So I have been browsing and gathering knowledge for quite some time now and always, it never fails, someone suggests something that kind of makes sense that screws everything up lol. So instead of doing more research and reading, i'd love to hear from everyone personally concerning my specific issues and questions. Thank you in advance.
btw - I do not have much moisture problems at all. Very dry basement.
1. I'm convinced that the best way to insulate my Basement masonary walls IN the basement is XPS rigid foam board on the masonry, stud wall over that, drywall over that. My first questions is, What's the best wat to apply the XPS to the wall? Glue? Screws(kind of defeats the purpose), or not at all and let the studs hold it up?
2. Is 1" or 2" XPS Rigid R-10 better? I've read that 2" is too thick to allow proper ventilation but i've also read that 2" would allow me NOT to use batts.
3. Do you recommend batts between the studs for this current setup and if so, unfaced? or which side should the face be...um...facing lol. ie are batts really necessary or will it constrict the breathing too much?
4. Should i take the XPS all the way to the concrete floor and ceiling joists?
5. Is XPS board ok to use in the rim joists or a combo of XPS and batt preferred?
