On attic insulation, I've been wondering. Say I have 3 inches of fiberglass insulation and want to add more. My "attic" is unfinished with just some plywood 3 or 4' wide running down the center line of the house. (I live in a single story home.)
Should I just get three additional inches w/o barrier and over lay it above the existing? It will then rise above the ceiling joists some, but that's no big deal. Is there any advantage or disadvantage to overlaying 6 inches instead of three, or is that a waste of money.
Anything I can do to tighten the seal around the pull down ladder cover in the ceiling?

The thicker, the better. Modern standards specify 12" of insulation in really cold climates. The R30 I'm putting in is 9" and thats a couple inches above the joists. I'm gonna build raised storage space by making 4x8 sheets with 2x4 runners to place across the joists so I don't compress the insulation.
For the pulldown, I backed it with foam board and stapled a flexible plastic lip around the edges to keep air from going through.
