Basement Wall Insulation Question


Ok so I'm remodeling my basement and trying to do it the right way instead of the way the previous owner did.

So far, I have 2" EPS on the concrete block wall, 2x4 PT wood for a plate under 20 gauge metal track with metal studs, all tapcon'd to the concrete floor. Now where I'm confused is, if I should put unfaced batts between the studs or not. I've had moisture problems in the past but I think the interior drains and sump pump will resolve the majority of the issues.

I usually don't put fiberglass batts anywhere in a basement due to it holding moisture/molding but I don't see the 2" EPS foam board really providing much R value.

Any suggestions?

Basement Wall Insulation Question


if the eps is well sealed, it is doing what is stated for its density, which is better than any wall can do, regardless of insulation type; the wood will lower the overall wall r value. you can always jam more eps between the studs, leaving a gap large enough for Great Stuff to fill. or, use roxul insulation. it is superior to fg in a couple of ways.
