Since these various rooms are in an
attic - insulation was important.
Unfortunately, the ceiling joists are
only 2x8's, so to get R-30 without

two 3" thick layers of rigid foam
insulation which provided us with R-30

the upper roof area.
As described above, we needed to use
high-density foam insulation in the
ceiling. It comes in 4x8 foot
sheets which were then ripped to size
with a table and hand saws.
Here's the contractor carrying the
sheets up the stairs of the house -

barrier to the foam we used a smart
membrane plastic over the foam.
