Insulate attic by adding fiberglass to top of plywood floor?
I have a 20 year old duplex that has its attic floor insulated with fiberglass between the 6 inch joists.
Some years back, I dropped in a number of half-inch 4x8 plywood sheets in order to use the space for storage. Most of the attic floor area is now covered with plywood, except for several feet on each side where it gets close to the eaves.
I was wondering if I could do anything at this point to increase the R-value of my attic floor without pulling up the plywood. Would it make sense to roll out some more fiberglass on top of the plywood (in the places where I'm not storing stuff)?
