1950s Southern California tract house with about 1200 SqFt attic. Basically, noodling on Home Depot's website, it looks like blown-in cellulose is about 1/3 the cost of fiberglass batts or rolls. But the center of the attic is decked and used for storage, so I am concerned about the dust issue since the attic will be accessed frequently (some say they get dusty and dirty every time they go in their cellulose-insulated attic).
Can anyone speak to their experience with the dust issue in going in and out of a cellulose-insulated attic? If you think dust is an issue, would a good solution (for the areas not covered with decking) be to use cheaper cellulose just to the top of the joist bays then lay perpendicular fiberglass batts over the cellulose to get the needed R-value and hold the dust in?
