So I am going thorough this same process in my 1976 Eleganza II. There are
indeed aluminum floor pans under the plywood, filled with expanding foam.
Im my case the expanding foam has continued to expand thorough the years
(or original quality control was crap) and the pans bulged downward, and
the floors upward. At the worst the foam was 3" thick. Anyway I have
removed the front two floor sections (7' X 4'), removed the aluminum belly
pans (they were just resting in the aluminum framing, removed all the foam
and, road gunk on the bottom, and straightened them out (back to flat). I
am going to be installing 3/8 inch thick Afromosia hard wood on top of the
plywood (in a teak and holly pattern) this will be water tight! So for my
underlayment plywood, I am going to use 3/4" Sturdi-Floor tong and groove
pine plywood (which is available just about everywhere).
As far as installation, I will be coating the bottom of the aluminum belly
pans with a quick coat of paint, installing them in place, then installing
rockwool high temp insulation into the area between the belly pans and the
plywood floor. Then the plywood. I thought about painting the downward
facing side. Any thoughts on this? Plywood floor was originally glued down
and screwed in place. The original glue was greenish in color, and when my
floor was originally layed down must have been after a three martini lunch
because half of the glue missed the mark entirely and even ran up the side
of the walls about a 1/2 inch in places. Anyway I have not decided what to
use as I put the new wood down, but the words of Jim Bounds are always
ringing in my ears "remember eventually whatever I do will have to be
redone". So any thoughts?
Oh and 50 percent of all the screws broke trying to remove them so I just
ground/cut,broke them off flush. I have not decided what to use here either.
