Help with block walls

I have a house that was built in 1925 out of ceramic block on all the exterior walls. The walls are stucco on the outside and plaster on the inside. I wanted to replace the plaster with drywall so I took the plaster down, put a vapor barrier in front of the block. Then I framed my new walls, put in insulation and another vapor barrier, then my drywall. After about a week I noticed condensation on the first vapor barrier and the insulation. What did I do wrong to create this problem or is that natural for block wall construction?

Hello and welcome to the forums.

Sounds like you framed it back up right against the block walls. Generally recommended to leave a gap, like an inch between the framing and the exterior wall. What you're describing sounds like a normal reaction from the cold outside and the warm inside ineracting. I guess you don't have the drywall up yet, since you saw the condenstion on the poly and the insualtion. Also, ceramic block? is this old fired blocks you're talking about?

Yes, they are the old fired blocks. I have seen them but never had any experience working with them. The gap you talked about does make sence and I don't have one now. I should be able to fix that pretty easy. Thank you for your input.
