Between floors

My 20-year old two-story wood frame house is in South Florida, heated only a few days per year. A/C the rest of the year. I'm taking off exterior sheathing/siding and replacing old insulation. I am wondering what I should be looking for in that space between floors in terms of insulation, and what could be improved.

From the outside you will probably not have access to that cavity, I may be wrong, but in any case I would expect it to have already been insulated. 20 years was just yesterday to some of us.

Page 10 of this DOE air sealing guide provides a cross section of what you are probably dealing with. It also shows where you should be air sealing from the outside.

Do you plan on adding a layer of rigid insulation over the exterior during your remodel?

No, not possible.
