Had leak that allowed the middle panel to sag/etc..
Pulled panel and cardboard backing stuff was krap.
Looking for a plastic (waterproof) backing to glue the headliner material to.
Any suggestions?? needs to be flexable to bend on sides.
At least that would fix the cardboard problem..
Now to find where leak is.

Thankx

Many people have used 1/8" Luaun plywood or 1/8" tempered Masonite for backing.

A lot of owners have used FRP, fiberglass reinforced panels, from Lowes or HD -- find them in the paneling section. Some cover them -- others leave them uncovered and use as-is.

Neglected to add -- recent threads about adhesive for headliner suggest 3M which will state on the can "for use with headliner"

There is no reasonable material to glue the original headliner vinyl material to. Many have tried, but it just does not work. You will need a new headliner altogether. Some have used a thin plywood paneling, some plastic, and some various other materials. There is a link to headliner replacement ideas, maybe someone will chime in with it. I don't have it right now.

Of course, find the leak first.

the PO had put in the FRP uncovered. that with the wood floor and all the cabinets makes for a harsh sound inside. i've been in other coaches that had a felt like material on the headliner and the sound inside was remarkably quiet.

Fred,

That other material is standard replacement headliner. It is foam backed
and stretches and conforms nicely. To see samples you can go to most any
fabric store. They usually have it - although in limited colors. It also
makes great padding for door panels etc. Cost is about $9-15 per yard
(54").

The problem is with age and heat the felt type facing separates from the
foam. It should last a good 10 years before that occurs.

Results may vary based on covered or not.

Tom, the stuff i'm thinking of is more like a carpet material with no foam underneath. i've seen it in SOB's a number of times. not to say what you are talking about won't do the same thing.

Ozite.

It's made thinner than the flat polypropylene indoor-outdoor carpet carpet
specifically for headliner use. I have it in my GMC -- but it really IS I-O
carpet (BIL in the business made it a good cheap option).

My site is one of the FRP panels mentioned in the gmc info site. As far as maintenance, the FRP is wonderful. It makes a nice looking ceiling that anything will come off of... including red juice boxes. With foil/bubble insulation, it is dramatically better than the old cardboard/snakebite interior. It is loud however. If doing the ceiling for an adult coach, I would consider some of the fabric coverings for quiet/low echo features.

The Carpet like material that has been used for headliner replacement
is made my Foss manufacturing. I have used it in several headliner
replacements and am again using on the Avion reconstruction. Here is
information on the material. I get mine thru Guske's. because they
have a supplier in Elkhart.

I use a 3/16" luan panel as my backing material although the 1/8"
masonite would probably work well also.

Another product worth looking at is KOMATEX, by Kommerling (German)
US web site is www.kommerlingusa.com . It comes in different thickness (all metric). White is available in 1mm, 2mm, 4mm, and 10 mm. Colored product is all 2mm. Colors are black, grey, dark blue, light blue, dark green, light green, tan, red, orange, dark yellow and light yellow. Finish is matte. Price quote on a sheet of 1mm white was $14 last year. A sheet is larger than a 4 x 8 sheet of plywood, so 5 panels would do a roof.
Since the product is designed for outdoor signage, I expect that it would hold up for GMC interiors. It is waterproof. I think you could glue almost anything to the panel.
Kommerling has dealers across the country. My nearest one is in Baltimore, MD or Richmond, VA.

Tom,

I used Komatex/Komacel for the interior side panels. I used automotive
upholstery cloth and the 3M heavy duty (headliner use) spray adhesive. I
mounted the panels to the aluminum frame with large flat head xmas
tree fasteners. Any product designed for exterior signage should do well in
the GMC. Eliminates that lamination separation syndrome!

Easy to use, cuts with a utility knife. Easy to cover with fabric using
adhesive spray. I may use a stock color for the window trim and upper
interior panels. I think it would be too noisy to use throughout the coach
without covering it.

Available in the Memphis area.

Works great!

The P.O. of my coach, Bruce Tara used this product (I think it is what he refers to as "non woven fabric") on the headliner of my coach. He did an excellent album on the photo site detailing how he did it:

I really like the material and am greatful to Bruce for doing such a great job. It was one of the best selling points, for me, on the coach.

The interior of my coach was re-done in Masonite. If it gets wet, it is nasty stuff. I would not recommend untreated Masonite to anyone. I guess that you could coat it with a waterproofer, but even that would be a hedge.

Sounds like the winner is Komatex or Sintra. Especially for the price and
durability to resist moisture. Not that water has any chance of getting
through all that sealer,

Sounds like the best way is to glue a 'fabric' covering onto FRP backing...
That's what I'm going to do with my cardboard backed fabric headliner sections.
At least it won't deteriorate when it gets wet..

I'm just finishing installing the inner panels on my coach using the Komatex. It's great to work with, and gives a very nice surface without worries of delaminating when exposed to water. When I pulled down the original interior panels, I certainly found the source of some of the "funky" smells that came with the coach when I bought it.

I haven't driven the coach with the interior panels installed, so I can't comment on any noise, but I'm planning on installing carpeting up to the beltline, so I'll see how it sounds when it's done.

I don't know how well the smooth surface will adhere to headliner material, but the material was inexpensive enough to experiment with.

I'm new to gmc's but i use "SENTRA" plastic sheets in my business for
displays and out door signage. i think it would be
perfect for a flexible,waterproof backer. it comes in 4'x8' sheets,1/8 to
about 5/8' thick. caution solvent will melt it, use water
based adhesives. it saws,routes, etc.
