Right now, we're in the process of finishing a room that we sectioned off in the basement, and we're at the point where we have to insulate the room. We used galvanized studs because there's a lot of moisture down there. One of the walls was framed along the foundation, and I'm not sure how to insulate it. I was told from a few people to put the foam board against the wall and then use regular fiberglass insulation.

I was wondering if anyone can tell me what they did and/or what is the proper way to insulate it.

What's the cause of the moisture? Is it leakage or humidity? I would be leery about finishing a basement that wasn't completely dry. You're just asking for mold problems. A lot of times you can solve the moisture problem with a little knowledge about it's cause.

But I was interested now to see something I had not noticed in 1984: in a long discussion on the flip side, "Why a BANKRUPT AMERICA?" there is a quotation from "Congressman Ron Paul." "I think it is high time that the American people found out exactly what the 'Fed' is up to in its domestic dealings, as well as in its relationship with foreign governments and international banks."

Well, it's an old house. The foundation only really leaks when we have flood-like rain storms, and to alleviate the problem, we cut a channel into the floor for the water to go into, so the moisture isn't so much of a concern, I guess.

I wouldnt dare finish the basement if I were in your shoes first without totally waterproofing and curing your water leakage issues.

I would use the reflective foam board over anything else, if it does get wet it wont turn to much like plain fiberglass or styrofoam.

Be polite. Be professional. But, have a plan to kill everyone you meet.

It's hard to say without seeing it firsthand but I would start by making sure your gutters work perfectly and the downspouts have extensions on them to carry the water 5-6 feet away from the house. Then make sure the ground slopes away from the foundation all around, at least a few inches per foot. Is there a sump pump and if so, make sure it pumps away from the house also.
Doing all of this should cure 90% of basement leaks. Then concentrate on sealing cracks etc.
Is the foundation poured concrete or concrete block?
As said before I wouldn't do a thing to the basement until it's 100% dry!

Just going by your basic post, I would paint the concrete surfaces with a crack filling paint (dry-loc, I think). After that has had a chance to properly dry, then get some Tuff-R foil faced foam insulation boards - 3/4" would probably be a good choice. Cut and glue the pieces to the wall, accordingly (BTW, if you haven't already put the studs up along the concrete, do these tasks first! - then stud it).

Run your wiring and plumbing (if any), then fill the rest of the cavities with regular fiberglass insulation, or get it done in expanding foam, and then sheet rock and finish!

I have my half-daylight basement done this way, and it makes a HUGE difference in keeping it warm!

Also good ventiation and heating will help keep it dry and warm.

It maybe worth install a sump pump, if it can flood, just to help limit damage when the heavy rain does come.

After all that hard work and money, you want it to stay dry for many years to come.
