Re: Sandwich flooring:
What Lou says has merit.
If you don't believe it. Bounce on the floor of the next airliner you get
on. That's not the thin carpet giving in. In some areas it works like a
miracle. Ideally AS floors should have fiberglass backing and retrofits
could use fiber glassed reinforced joints. Kevlar could be used in some
applications but is expensive.
It's a lot easier to put in a new floor when just working on a chassis.
Large pieces cut to exacting standards do not navigate the AS door easily
and once down to not come back up easily. I put a new floor (door forward)
in a 69 Safari and it took many trips in and out to get it exactly right.
That replaced plywood floor and the old floor is now going to be topped off
with either wood laminate or new synthetic Bruce type products except in the
bath where new tile will be installed.
