Well doing research on my basement project (1300 sq ft in Northern Va) I hope to reduce the chances of future mold issues. Here is my scenario:
House is 4 years old, poured concrete walls and the basement is a walk out where the back and half of the sides are above ground. I first put up the basement walls keeping the rolled bat insulation and built the stud walls about 3 1/2 inches out from the concrete. While the basement walls have no water infiltration and is dry as a bone in the winter, I noticed quite a bit of water condensation in the summer sweating and soaking the bat insulation. It got soo humid from this the hvac sweat at the main trunk for the first couple of feet. So I decided to read up on how to fix this before going to drywall. i realized bat insulation is about the worst thing I could have used regarding thermal break.
Reading Dana's posts here and a couple sites listed, I have ripped down the bat insulation and purchaed 2" XPS foam board that I will glue, tyvek tape and spray foam the seams to make it tight... There might be a 1" gap though from the foam board to the stud walls...
I wish I used that cool BLU wood you see now on all of the DIY programs, but too late I already used regular lumber with the treated lower plate. Anyway I read about this Boracare Mold care spray treatment I can put on the framing.. Seems like for 130 bucks not a big deal to do... Not sure how effective this might be
Last but not least I decided to go with the Mold Tough drywall that has the treated paper face on both sides and treated core. I do not want to use a fiberglass based board or paperless that needs skim coats so this product looks to be a great compromise over regular drywall. it is only a couple bucks more over regular drywall. Not sure why they sell the regular stuff anymore lol
Any insight on where I am going wrong or any ideas before I close it to drywall? Thanks.
