A lot of people ask me about the fabric on my walls and ceiling. Well, it's actually my insulation! In this video (here), I show you how I insulated my van with foam board and fabulous fabric - with a little help from my friend Robert. Its an easy, quick, inexpensive way to get your rig insulated and ready for the road. Happy and safe travels!

Materials Used:
- Foam Board Insulation, 3/4" and 1" thick
- Liquid Nails Heavy Duty Construction Adhesive
- Loctite® PL® 300 VOC Foamboard Adhesive
- Fabric, various sizes and types
- Scissors, Single blade utility knife
- Bungee cords, poles or anything else that works to secure covered boards to walls and ceilings while drying

NOTE: Although the heavy duty, industrial strips of velcro would probably also work for adhering the foam board to metal, I chose the Liquid Nails adhesive to keep the cost down. Plus I didn't want to "rough up" the surface (for resale later). The liquid nails adhesive used in this video has continued to work really well.

I hope this helps with some new ideas, and that you enjoy the video. Thanks!
Saw your video demonstration of this last week --- thought it was an inventive and colorful way to get something we all need completed. Well done!!!
I already knew I wanted fabric on the walls, but I thought I was going to have to wrap plywood, so I loved seeing this in action and I'm pretty sure (I'm such a waffler right now) I'm gonna go this route!! Thanks for the great demonstration, Debra (and Robert)!!
Debra: thanks for sharing this. We need to redo the walls on our old motor home and I had thought of using fabric but hadn't thought how, so this is a wonderful idea. We were going to use wood but that would add a lot of weight. My one objection ( for me) was how to keep it clean. I could picture myself opening a can of pop and it spraying all over and ruining my fabric. (I'm prone to make messes). Do you have any thothoughts on how to protect the fabric? I had thought of maybe using polyurethane or varnish over the fabric. Does anyone know if that would ruin the fabric or insulation? Does anyone have ideas of what would protect the fabric? Great idea and video Debra, thanks for the video. I'm excited about this idea. Nora
Jaxtonsgram: Use upholstery fabric, and spray it with Triplex Green Guard protectorant, which doesn't have the flurocarbons like ScotchGuard. Here is the Material Safety Data Sheet (MSDS) for it, which appears to indicate that it's only dangerous if you drink it or rub it into your eyes: https://www.sun-beltusa.com/skin/fronten...S_2015.pdf

It costs about $40/gallon, but it should be diluted. I don't know if it comes in a smaller (like a quart) container -- don't see it right off. It's also good for protecting carpet. If you have a local upholstery place, talk to them and see if you could buy a smaller container, or at least buy it w/o shipping costs. Also, there may be other brands of a similar VOC-free product.

From their website:
Directions: Use as a topical spray or add to your cleaning solution.
Dilute 1 to 9 with water and apply at a rate of 600 sq.ft. per diluted gallon.
Total coverage area: 6000 sq.ft. per gallon
Thanks train chaser. I'll check into that. Nora

TrainChaser, thank you for replying to jaxtonsgram, Nora. I wasn't online yesterday. Nora, I was going to say that I used scotchguard on my fabric, but I really like the non-toxic solution TrainChaser provided. TrainChaser, I have a few people that have asked the same thing on my YT channel. I am going to share this info with them too. Thanks again to both of you!

Thank you Thirsty Boots Nomad and AbuelaLoca (both of you have great IDs btw). I'm glad you found the video helpful. Best wishes!
A belated thought on the gallon of flurocarbon-free fabric protector: If someone HAD to buy a gallon of the stuff (the only option), maybe you could 'share' it (liquid and cost) with others who like your idea. It certainly appeals to ME, as I was planning on doing almost the same thing! Like.... if you were going to be at the next RTR.....
Fabrics? Consider testing the watery silicone-based sealants intended for grout and concrete. I do leatherwork and woodcarving, so I was looking for a sealant that wouldn't change the appearance of open leather. Tho evey sealant intended to be applied to these materials failed the appearance test, the silicone grout sealant from home depot worked GREAT.
Might work here, if fabrics are mounted?
