My basement walls are poured concrete. I live where winters are cold. I am
planning some enhancement of the basement (family room, workshop, etc). The
basement is fully heated by the central heating system.
The walls are very cold to the touch, particularly above the frost line and
even more so where the walls are above ground.
I would like to provide some insulation for these walls. I do not want to go
the expense and time consuming inconvenience of installing studs, glass wool
all around the basement which is 40' x 40'.
Are there any products, perhaps in the form of boards, which I could install
directly against these concrete walls, maybe using construction adhesive? I
have no need to use these walls for support of shelving, etc. I seem to
recall that rock wool boards (8' x 4' x 1.0") are available but I don't now
where I saw these.
All advice/comments are welcome.
