The problem with fiberglass like that is that it needs about 3.5 inches of
space to have the R13 value. If you compress it to 1 inch, you will have
about R4.
Beating foam for insulation effectiveness is hard.

DO NOT use Reflectix in the generator compartment. Overhead maybe but it is highly flammable. If you doubt me, simply take a 1" x 4" piece of it and put a match to it. It makes a good campfire starter. I caught hell for lighting a small strip of it indoors during a seminar one time.
If you want to use that type of insulation, I suggest you use Microfoil from Northern Ohio Foam Products. It will burn only if a flame from some other source is held against it and it will not sustain a fire on it's own.
We had a group buy from them about 10 years ago and split it among a bunch of GMC coach owners in Indiana, Ohio, and Michigan. They will send you free samples and will sell direct and ship product to you using UPS. I toured their plant in Wauseon, Ohio a few years back
Get a piece of reflectix and hold a match to it. Then stand back.

Second vote for Microfoil. Easy to work with. With minimum order, you can share with several GMC's. I did front cap, and headliner, front to back, and had enough material left over to do it again.
Will not sustain a fire without a flame from another source.

I would have suggested reflexctix, but now Ken is going to make me go do his burn test on the stuff I lined my fridge with.
Sorry.... But if you ever have fought a fire (and won) in a GMC, You would be very cautious about what you use inside of one. Almost anything will burn. It is just how fiercely it burn and how hard it is to put out. I had a major gasoline fire in the engine area years ago and the hatch was covered with Microfoil. It did burn but from the gasoline below and it did not help spread the fire. I am still driving that coach today. I heard but have never seen in writing that Reflectix was banned for use in new RV's being built.

Seems like there are way too many GMC fires.

One GMC fire is too many. They are no more prone to burn than any other
brand, but, they are 40 years old, and shake, rattle, and roll down the
road. They were intended to be maintained constantly, not ignored.
Gasoline, transmission fluid, propane, batteries? What could possibly go
wrong? Hot exhaust systems, mice and squirrel nests, the list goes on.
Simple tests with electrical testers, soap bubbles, your nose, go a very
long way towards heading off disaster. Fire prevention is one part of the
cure. Fyr-Fyter type of on board foam or chemical extinguisher systems is
another. Both east and west Jims have excellent products that are very
effective.

The big thing is to focus on prevention. The second thing to focus on is extinguishing a fire should one occur.
It appears that most RV fires are near the engine, generator, or refrigerator. On mine the carb flooded over and a blown gasket in the intake manifold cross over choke heater tube provided the ignition source. Shorted wire from the fire kept the fuel pump running and supplying additional fuel.
On the prevention side things like using non-combustables near possible fire sources, disconnect switches on battery banks, elbow and hose on top of trans at vent with a runoff for fluid away from exhausts are a few things. Heat shield around Onan is another. Fix any gas tank leaks especially on top where it can flow near exhaust. There are probably 10 more items.
On the extinguishing side, availability the correct type of fire extinguisher is a must. AR-AFFF (Foam) is my preferred extinguisher type. Optional Automatic deployment installation is a plus. I have auto deployment Halon in refrigerator and Onan areas because they are confined areas where halon will work. Unfortunately no vendor is offering an automatic deployment foam system for the open engine area that will not freeze. It could easily be done. So I carry multiple hand held foam fire extinguishers to be used around the engine, trans, and fuel tanks.

The last time I went there, we had a Sunday lunch scheduled somewhere in Michigan. I took my coach to the plant in Wauseon and we filled it with rolls of the stuff. Some double reflective and some double reflective with added white covering on top on one side . People wanted that for windshield covers.
I believe that I got something like 13 rolls at the time. Then the next day at lunch we divided it up among the people that ordered it.
