My house has an unfinished attic with a partial floor (maybe 1/8 of
the attic currently has a floor). I am quickly running out of storage
space and would like to put down some simple plywood on top of the
floor joists to serve as a floor for storage. There is currently blown
in insulation through out the attic.

Do I need to remove the blown in insulation and replace with rolled
insulation? I have heard that blown in insulation works best when it
is not compacted, and putting the plywood on top would compact it. But
I have also read some posts around the net that suggested that it was
not necessary to remove the blown in insulation.

Any thoughts or ideas?

Thank you!

Mike
