- I understand I'm not in the ideal scenario, but - what would be the best way to go from here?
My basement walls are already built (2x4 walls about 1/8th inch from the poured concrete - some areas are touching). Behind the 2x4 wall is 6mil plastic from floor to ceiling. Bottom 2x4 is treated lumber.
I realize this is not ideal, and have read a lot of things about how it would be much better to have the large EPS sheets THEN the wall, but - I really don't want to tear down all the walls to put that up behind.
I have not had any water problems, dampness...etc at all in my basement. I've done the plastic test on a few 3'x3' areas during very rainy days, and saw no moisture build-up (but have read that condensation can happen once you start insulating).
My current thoughts/questions/options:
- do I pull the plastic or leave it? Or pull it and put plastic up over after the insulation? If I leave it, do I need to go around and make sure it's sealed better? (currently duct-taped together in overlapping spots)
- do I use normal insulation, or buy 14.5" sheets of EPS to put between the studs? If I use EPS, so I need some kind of caulk between it and the studs?
- if "normal" insulation, should have it have a paper face or no?
- it seems like sheets of EPS put in-between the studs would help from an anti-mold perpsective, but... would that insulate well? Also cost a lot more I assume, but...
ANY suggestions/helpful hints/thoughts are welcome... there are MANY resources for "how to finish a basement", but very few (none) that would help on where to go once you've already started down the wrong path.
The goal is to finish the basement completely with nice rooms...etc as if it were a normal living area in the house.
My house is in Ohio - it gets very warm, very cold, and and wet - just about everything.
Thanks VERY VERY much for any help!
