I have a sunken family room (by design). On one of the exterior walls I am
getting a lot of cold air either convecting or blowing in. I am kind of
confused as to the sources as I recently completed my basement and insulated
the joist cavities at the rim joist pretty well (foam insulation glued to
the rim joist).
I am thinking that perhaps the design of the sunken floor has left a cold
zone that I didn't see at the time and therefore didn't insulate.
Anyone have any experience with framing a sunken floor that might give me
some insight as to what to look for. From what I can see/remember, the
foundation wall is the same height all around the house meaning that they
didn't lower the foundation to create the sunken family room.
Looking forward to your thoughts...
I know the truth is out there, but I like to stay in....
