Drywall in coach?

Scott & Heather · July 05, 2016, 05:23:18 AM

Have any of you ever used drywall for any interior walls? Not side walls, but interior walls that will never see thermal conduction from the metal framing

I have never seen it used in any coach I have been in, but it would have the advantage of being fire retardant. With the changing temperature and humidity levels in a coach, plus the vibration and slight twisting, I suspect that it would not survive well, and it might add unnecessary weight.

It seems to hold up in the RV market on the travel trailers and motor home,I know it takes a special tape and compound with a wider space between the sheets.I had to replace a sheet of 1/4 inch before in the daughters 5th wheel.lol a 50 story building will move more than a bus and they use sheet rock

I have had 1/4" drywall in my bus for 10 years, but my RTS does not flex.

Daryl Loper has had 1/4 in in his MCI 9 for over 15 years with out any problems also and he has it on the outside walls too over 1/2 inch plywood

Something like "Tough-Rock"?

Type X is fire retardant. Regular sheetrock will burn just a little slower than wood.

I was thinking about installing a paintable wallpaper over plywood walls. Painting it with a thick coat or two of latex would probably make it look like drywall... just a thought.

We traveled the Gulf Coast and Florida in the bus last December and January. The humidity is high, with lots of rain. Everything is dripping wet. Things get rusty fast. I would not want dry wall in the bus. I picture it ending up in a wet, soggy puddle on the floor... If you use it, you should paint it both sides with good paint to seal it good.

Green board sheet rock is made for high humidity areas that is what most bathrooms have

Use good furniture grade plywood-you'll be much happier with the lack of maintenance as compared to dry wall. Good Luck, TomC

Sheetrock needs framing support for interior walls, therefore the wall will have more thickness. A single sheet of good 3/4" plywood can serve as a wall on both sides of it, and will serve as a good attachment point for screws.

Yes along those lines, the bathroom walls on my bus are 3/4" furniture grade plywood (birch covered). Painted on the bathroom side, varnished on the outside. You won't be able to have a 3/4" wall made of Drywall. Good Luck, TomC

Thanks team. We took the plunge and installed drywall. I'll let you guys know if I regret it. Used the green rock (moisture and mold resistant). Since we Fulltime in our coach, it is very consistently climate controlled. We never let it get hot or humid or cold in the coach as a general rule. Anyway, we shalt see.
