I Just moved into a new three level townhouse. All Three levels are
above ground. The front entrance is between the 1st and 2nd levels.
Stairs go up to the living room and stairs go down to a hallway which
leads to the garage door and basement area. Under the stairs leading
up there is a closet which leads to a crawlspace under the foyer. The
floor is concrete, there are two finished walls, one abuts my neighbor
the other the garage. The wall with my neighbor is insulated, the wall
with the garage is drywalled so I don't know what is in there. The
third wall is concrete which is exposed on the outside as well. This
closet is freezing, which makes the hallway and foyer cold. The floor
in the foyer is fairly cold as well. I am thinking I definetly should
insulate the ceiling, how about the concrete wall? Will foam board
insulation be effective? Do I really need to install drywall over it?
The wall is only 3ft wide and there are no mechanicals in the room.
Here is a diagram of the lower level in case it helps. My scale is way
