Window issue...AGAIN, sorry....Need some advice?

2) Also, vapor barrier plastic completely gone. I see fix to get some 4 mil plastic to replace, but is it IMPORTANT to replace the barrier? Is Carbon monoxide or CO2 a risk?

:grinp:

Thanks Tom for mentioning the vapor barrier....I had posed a question about it at the beginning of this thread. Mine are both completely gone, now I think I should put some plastic up. Think moisture damage/mold is the only down side to not having them?
