But I've seen the tops of the tiles used for the storage of batt insulation many times. So much that it had to be removed from areas to ACCESS the area above to perform essential functions like repair a loose connection in a junction box or even replace a damaged tile. Many times I've sen the workman standing on a ladder with more than half his body in the space above the T-bar. This is obviously accessibility for both storage and people.
