Hi Creekside, sorry I missed your note.
The bottom of the roof (ceiling I guess?) is probably closer to 1/8 " and then there's 1" pink foam atop that, then finally the upper plywood layer that is also a thin section, again probably 5mm or 1/8" as I recall but I'd have to jump back into the forum and go digging to be sure. Again, sorry I missed your post, let me know if you have other questions: r67northern@hotmail.com

I enjoyed looking at your remod photos of your HiLo. We have a 17' 1976 HiLo. I am wondering what you used to replace the ceiling in your camper. We had to pull down our ceiling to repair water damage from a leak that began over the shower exhaust fan. The plan is to put insulation in the ceiling. It looked like you put 1/4" plywood and painted it after installation. What did you use? Thanks! I enjoyed your photos and the verses.
