Basement Insulation Wrap

I am in the planning phase of a a large basement finishing. The builder nailed an insulation wrap "teddy bear" (not just a housewrap - but fiberglass behind the covering) around the entire poured concrete exterior wall. The basement is 6 years old and has been very dry. No sign of water anywhere. I was planning to leave the insulation up and frame the walls leaving this within the vapor barrier between the Concrete and Framing.

Does anyone see an issue with this?

Welcome to the forums! Actually your vapor barrier should be between your wall covering (drywall) and the studs. This will keep the moisture at bay behind the wall and will dissipate via the circulated air. You can leave up the stuff you have at present, as the basement walls, if underground, are geothermally correct anyway, and need no further insulation.

Thanks much, I feel better - I did not look forward to pulling down the insulation.

how you put the furring wall on top of the insulation

I was wondering how you put the new furring wall without taking off the insulation.

Concern about mold between insulation blanket and foundation wall

I would be concerned about moisture building up between concrete foundation and the insulation. Perhaps not a problem now...but could become one once you start heating the space. Check out the PDF at

I found that article helpful when finishing my basement.
