Hi Steve,

The size of cavity isn't really a concern, in the house Robert mentioned above the entire wall was open. There are offset 2x4s on the interior and exterior of the wall, so the entire length of wall is effectively one giant cavity 15 inches wide. But doing dense packed cellulose walls isn't really a DIY sort of insulation technique, so its more about finding a reputable installer that will do the job properly.
