We live in a modified cape home. On the second floor we have two bedrooms and a unfinished room that funtions as an attic.
There is insulation in the ceiling of the attic, but when we moved in there was no insulation in the walls. We stapled in Miraflex insulation, which comes encased in a sort of plastic.
We did not use a vapor barrier under the Miraflex.
Now we would like to put up wallboard to cover the insulation. Do we have to take the Miraflex out and install a vapor barrier or can we just install the wallboard?
