Thanks to jaros for bringing this issue up, yet again, about asking people to identify where they are located.
With New Years resolutions and all, I for one, aim not to waste anymore of my time asking people for this basic info when I reply to legitimate questions to which I may have a contribution to make. I'm not holding my breath though, as 'dumbing down' of bbs to satisfy every yokel on the planet seems more interesting that the quality of contributors...
I'm not poking fun at DIYers - this has nothing to do with the purpose of this bbs; but I can't fathom the justification for not asking people to fill in what corner of the globe they come from. Seems simple enough...
But to help the OP out, I read that the builders probably did the minimum code requirement for the outside walls of his foundation by putting up - in his words - "a waterpoof insulating material". Unfortunately that doesn't say much since there are dozens of configurations out there that fit that description.
But that means that the builder has put up something that will prevent bulk water from entering through the mortar and cracks of his block foundation. Doesn't do squat for 'insulation' nor for 'vapour management' - it's not meant to. So those two issues are to be dealt with in Ohio.
So the walls need R13 or more on the walls, something like that, i.e. about 4" thick of some insulation whether it's XPS or fibreglass batts or whatever. So right there, he'll be looking at something he can either build or put up himself...Now the answer to that depends on what he wants to do inside...drywall maybe?
He'll also need a vapour management system of some kind to prevent the warm air inside from condensing on the cold outer wall. Faced fibreglass batts? Maybe but definitelty one of the Class 2 vapour retarders...
But to be really effective, he'll have to airseal the rim joists and other penetrations where cold air can come in, otherwise all this insulation and vapour retarder work is like peeing in the wind. May feel good but you'll get the worst of it soon enough. :laughing:
We'll need a lot more info to be able to guide the OP through the best choice to make in his particular situation but those are the bare bones of it.
