I love this forum, but I hate this topic. I have done a good amount of research, and get so many conflicting answers.
I live in Westchester NY (southen NY).
I have a finished basement which was ruined by hurricaine Irene. It was old, witch warped wood paneling, so not a huge loss.
I pulled off the wood paneling, and found that it had 2x3 framing done at inconsistent intervals. I tore that down.
Now I have an exposed, but painted cinderblock wall. My idea is to glue 2 inch XPS foam (Pactiv 2 inch foam, R10) to the inside wall.
$32/sheet is expensive, so I want to do this right.
The cinderblock is painted, so I do not need to apply anything like drylock, right?
Can I can adhere the foam directly to the cinderblock? If so, using what adhesive?
To run electrical, can I route channels in the foam?
I do not wish to redo the electrical. All runs drop down from the ceiling. They are in metal sheathed casings. Do I need a nail plate?
In terms of moisture, is this a good setup?
I apologize if this post is redundant, but as I said before, I have gotten so much conflicting advice.
