RE: XPS Taping (Follow-Up #2)

Contractor's sheathing tape is what should be used, not duct tape. (Which should never be used on ducts either.) The most popular brand is Tuck, right up front in every HD I've been in.

RE: foam board thickness - 1' or 2' ? (Follow-Up #1)

Assuming you're in a Cold Zone, not a Very Cold Zone, one inch XPS is sufficient. (For EPS, I'd put in two inches.) It just means you'll need a little more of whatever other insulation you are putting in between the studs. Same for metal framing. Just be sure the base is on 1" XPS; metal framing doesn't take kindly to water.

RE: Another polystyrene basement question (Follow-Up #4)

Up to 50% of the heat loss in a tightly well-sealed home is through the basement. It's less--20%-35%-- in other homes only because there is even greater heat being lost everywhere else.

The biggest source of heat loss is the portion of the basement that is above-grade, including windows.

Concrete screws come in lengths up to 6". There are lots of ways to secure the foam. Whichever works best for you and suits how you're finishing basement is the one to use.

For instance, I just came across this way of securing foamboard. Other methods include: gluing the foam board to the wall, then gluing the drywall to the foam; or securing slotted XPS to the wall with furring and attaching the drywall to the furring strips.

combustibile construction

If there's exposed wood, it's combustible, and typically is required to be covered by at least 1/2" drywall.

Good advice! A method I've used is to rest the bottom plate of the stud wall on a half-inch of Styrofoam and cut the drywall an inch up from the floor. I've also framed with steel--less food for mould. And no nail pops.
