Ron,
When I put the headliner in my X-Birchaven in '98, I used "duct board"
(Masonite coated on one side with white Melamine, making it totally
impervious to water) for the substrate, white site up. I installed all of
the panels in my gutted coach, by cutting them to length and width and
popping them into place as others have suggested. Only a few pop rivets
were necessary to secure them to the ribs. Rather than use trim strips at
the joints, I glued a single piece of polypropylene Indoor-Outdoor carpet
to the panels, covering the seams. The I-O carpet is like "hull liner" but
2-3 times as thick -- it was cheap since my BIL is in that business.
To mount the carpet I built a "dead man" consisting of a single 2x4 beam
down the middle of the coach supported by vertical stanchions. I hung the
carpet over the beam, then sprayed high temperature contact cement on the
panels and the back of the carpet in end-to-end stripes, adhering the
carpet as the cement set. Working side-to-side, the carpet went into place
quite easily -- much more so than one would expect. It's still there 19
years later and looks almost as good as the day it was finished. I like
the seamless ceiling from the front cap to the rear cap.
The I-O carpet is impervious to almost everything -- I could clean spots
with lacquer thinner if necessary. I could have chosen a better color than
the light grey, but we still like it. A couple of small "bubbles" have
developed over the years. Tiny cuts hidden in the pattern of the carpet
admitted a spray nozzle and cement to fix those quickly and easily. The
biggest problem is that it would be impossible to do any repair,
replacement, or modification in the ceiling without cutting the carpet and
then installing trim strips. Since all of my panels extend side rail to
side rail, I'd never attempt such anyway.
