On one wall I have to install insulation, but unfortunately its going to be
installed on the wrong side of the wall for the vapor barrier. I personally
haven't found a source for insulation that doesn't have a vapor barrier -
otherwise this would be a moot point, but I'm wondering if I can just push
the insulation into the wall - vapor barrier and all. It should stay put
from friction but I didn't want to just start stuffing it in there and have
it turn out to be a bad idea.
The vapor barrier on fiberglass insulation can be peeled off quite
I last bought fiberglass insulation in 2000. There were several
choices of "no-vapor-barrier" insulations available then. Are you
sure you looked hard enough?
If I understand you correctly you are working from the cold side so the
vapor barrier should be on the other side. Yes you normally could use just
friction fit. As noted the barrier usually comes off easy or you can slit
it if that is not possible. I would use friction fit to keep the barrier
where it belongs.
By installing on the wrong side, if you mean you're installing it from
the outside of the house then push it in with the vapour barrier on
the warm in winter side - the inside if you are in a cold area. If
there is already an inside vapour barrier then you sould slice the
vapourt barrier on the new insulation so you don't trap moisture in
