Hey all, new home buyer, so I am new to this forum. Sorry if I missed a similar article, but I am stumped. Half of my living room is under other living space like the master bedroom, the other half is not (exposed to outside air). A steel beam supports the floor above one side below living space, one side not. I will be insulating above the exposed ceiling with fiberglass, and adding a Durovent rafter vent between sheathing and insulation. My question is, what is the best way to insulate so the other side doesn't get cold air in the ceiling, and how to keep the air flowing as to not allow moisture to build, and mold to set in. I am thinking about putting foam board as a block from side to side with some holes in the board as to allow a bit of air to flow, but not to much.
Sorry, it's confusing, but any help would be great. Thanks
