Hi. We have recently bought a house that has crawlspace approximately 250 sqft, which sits below the family room. The rest of the house has a basement. there is an entry point between the crawlspace and the basement.
We live in Norhtern VA, so zone 4. Our family room is colder than the rest of the house, partially due to having no rooms above the family room and the crawlspace below.
I wanted to improve the coldness, by adding insulation above and below.
The crawlspace is vented and I have a question about the current insulation.
There are fiberglass batts in the floor above the crawlspace. There is rigid foam board on 2 of the outside walls. The other walls do not have any insulation; one wall shares a basement wall and the 4th wall is an inside wall. The floor is has the poly runs up and taped up over 12" on top of the foam boards and also on the concrete walls without the foam board.
Trying to do my research, it is either insulating the floor above or the walls.
My question is this: Is it ok to have the rigid foam boards on the 2 walls?
Also, would it be ok to add foil-faced foam board to the floor above, the foil facing towards the crawlspace, and leaving the current fiberglass batts. I am not sure if the current batts are paper-faced or not.....it might be unfaced.
Thanks!!
