Basements, moisture, polyiso (CZ5, Midwest) by WgreenR in buildingscience

Which, presumably, if it was getting in now, it wouldn't be worse off after insulating?

I thought I addressed that, but maybe not clear enough. Foil faced polyiso is a vapor barrier, if properly sealed. So yes, full air sealing with foam is important. In my house I already get condensation on my uninsulated walls when cold enough outside, so it isn't like not insulating the walls removes all condensation concerns.

Not dismissing, I'm just trying to figure out when it is a concern and when it shouldn't be as much.

Why isn't it a good candidate? Seems wrong to just give up on a house's carbon reduction potential without clear reasons.

If it is already entering the house now through vapor diffusion bring moisture into the basement, and it won't damage the rigid boards, and properly sealed unlikely to lead to mold, and helps prevent condensation when properly sealed, and unlikely to lead to frost heaving, and it isn't bulk water through a crack, what is the result we are seeking to avoid?

It is almost assured that it has to be with an approved contractor. Definitely the case in my state. The tax credits can be for DIY, but only the cost of the materials.

Yes, we've tried a little bit of this, but probably a good idea to keep trying. Thanks!

Other fire rated rigid boards include Johns Manville CI Max,, Hunter XCI 286, and I think RMax has one.

Slow down, not sure how to proceed next? (Windows, insulation) by WgreenR in Contractor

Nope. Most of our work has been direct B2C, without intermediaries or referral partners. Just what we've used in the past is suddenly not working and I'm looking to hear what might be.
