We have a pressed cardboard tiled ceiling and blown-in insulation in the attic above it. It's ugly and we'd like it replaced with sheetrock that we could paint.
How would I go about determining if our ceiling joists can support the added weight of sheetrock? Should we remove the cardboard first? (We've gotten negative lab tests. For asbestos and so we are certain it's plain cardboard). If the old ceiling must be removed, how do you do that without all the insulation falling down?
