Default putting on insulation backwards

Shove it in with the VB the correct direction, friction will hold

On one wall I have to install insulation, but unfortunately

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.


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.

Alright, just checking. Another person asked why I wasn't
looking too hard for non-backed insulation and the answer to
that was because I have a bunch of rolls of backed insulation
already.


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
the wall.
