i went to buy it, but it says it is not fire retardant. doesn't the material have to be fire rated?

Here is a quote from the PDF at the Johns-Manville site: "Fire-Rated Assemblies
EnviroAire, Mat-Faced Micro-Aire or SuperDuct RC, 1" (25 mm) thick is
accepted in lieu of sheet metal duct in many fire-rated assemblies. See
UL Label for design numbers."

this would be a lot cheaper than boat insulation which runs about $300 dollars for a 4x4x2

Pierce, I just this AM checked with a local supply house on DUCTBOARD.  According to the MSDS it is non flammable but I could not find any data about the facing which is aluminum foil embedded with what appears to be a fibreglass strand for reinforcement.  It comes in 4X10 sheets at about 35 bucks a sheet.  In addition to the foil facing it also has a backing that appears to be some kind of fibre, probably recycled paper.  I believe this is what I am going to use to reline the engine compartment.

Gary,

I didn't look at the MSDS, but the front has printed label said it will burn if exposed to flame. I could be mistaken, but it said it was only fire rated when used in conjunction with drywall. anyway here are some pics from my renovation yesterday.

Robhatric, The brand I was looking at is by Owens Corning.  The MSDS says non flammable, and there is no flash point or flammable limits shown it also shows no boiling or melting point.  So I would think that it will be safe to use.
I am not going to try to remove the crumbly foam now in place, I will run a vacuum over it to remove loose stuff and then put ductboard over it using aluminum tape on the edges and to secure it to surround.

Gary,

It's supposed to be a layered fiberglass construction. Don't think recycled paper would pass fire testing. Generally, the thicker the material, the better the fire rating. That's why garages require 5/8" drywall instead of 1/2". Not that I'm a fan of drywall/stick construction.

According to the spec sheet below, a layer of Owens Corning QuietR Duct Board should give 30 minutes fire protection.

thanks Jim, that looks really nice.

Also fixed the storage latches today. Some of them were not latching, so I took them apart and it was filled with dirt and grease that the previous owner was lubing it with. The angle hooks on the inside were all bent and some of them were not catching. Straighten them out and they work perfectly. I do have one door that has the fiber glass that is coming off the main part of the door, which would be an easy fix if there was a way to take the door apart from the coach.

Robhatric,
Start a new thread when you want to tackle it and include some photos so we can understand exactly what's needed.
There are many threads on the subject.  You can search for terms like "bay door", "storage door", replace door with hinge, etc.  Here are a couple (one I had started):
Bay Door hinge failure repair (I think this one sounds like your problem)
Bay Door Hinge Replacement with Stainless Hinges

Craig,
I seem to recall from an post a long time ago that you had purchased some of the peel'n'stick Unisolar panels for your coach. Did you get those installed? Any observations about the install process and or performance of these panels? I would be interested to know how you like them as I have about 400 watts worth of them waiting in my project hopper to install... attached is a picture of a test fit that I did back when we first got them.
Thanks, Don

I'm sure planning to keep my 93 U225. And also planning to use it a lot in Mexico. The low profile and 8-foot width is invaluable for narrow roads with low bridges.

Robhatric: they are a work in progress. It helps if you have a place to park them where you can work on them. But they're designed and built so well that working on them - while still a lot of work - is not a chore.

We have replaced the battery charger/converter (high priority!), added a pure-sine inverter, added a battery systems monitor, added solar panels and MPPT charger, replaced the forward TV with an LED, added an LED TV in the bedroom, and put a new tile floor in the bathroom. All since December of 2011.

Plus wiring repair... but that's another story. :P

Welcome to the group.
