Has anyone considered using "Great Stuff" Foam Insulation that you get fromHome Depot to insulate floor cavities? I am considering "foaming" the baggage compartment side walls and floor however I would hate for the properties of the foam to "eat up" my plane.

I don't know about using it in an airplane but I've used it in boat
before. Works great(hense the name duh).
I know great stuff makes two types of foam. One that forms open
cells and one that forms closed cells. I'm pretty certain you want
the one that forms closed cells. Open cell foam will act like a big
sponge and soak up water, fuel oil, etc. you get the idea. I'd
suggest you find out if it is flame retardant or not. You don't
want to be sitting on foam that will go up like a roman candle!
Be carful putting this stuff in an enclosed area. This stuff expands
quite a bit and could due alot of damage If there isn't a hole for
the excess foam to get out of.

This question was asked just the other day on the "vansairforce"
yahoo group, and there were MANY replies. The gist of the replies
was...DON'T DO IT!!!!!!!!!!
Reasons given were
1) the stuff is FLAMMABLE (or is it INFLAMMABLE? always got that
part of English class mixed up). It SUPPORTS COMBUSTION...it BURNS!!!
2) Someone said it produces acid as it cures. Not the kind of
stuff we'd like to have in contact with aluminum.
3) Once installed, it's not as easy to remove as other types
of insulation.
4) Some hydrocarbons...like aviation fuel and oil... turn it
to an oozy goo.
5) It traps moisture...not good for an aluminum airplane.
It doesn't sound like it's GREAT STUFF for an airplane. I have used
it at my house, and it is GREAT STUFF around windows and for general
weatherproofing. IMHO.
These are my recollections of what was posted on the other group.
There is much more discussion there on other options for
insulation. Most of them suggest an aluminum backed fiberglass
board available from Heating, Ventilation and Air Conditioning
(HVAC) supply houses.
You should probably go to the "vansairforce" Yahoo group to get the
REST OF THE STORY...
Hope this helps.

Tim,
I just noticed you were the one who originated the question on
the "vansairforce" group. I guess there was a lag time in getting
your question posted on this group. I decided to leave my response
on this group for the record.

Just a few of my thoughts on the "Great Stuff" idea.
1. I "think" that type of foam will absorb and hold moisture if
exposed in some way. You may not be able to dry it out if it got
wet.
2. Fumes from burning / smoldering may not be such "great stuff" in
the cabin.
3. Difficulty in repair / access since everything would be "glued"
together.

Tim:
I don't think the answers here are going to be much different than
the generally unanimous "NO" you got on the same posting yesterday on
the vansairforce site.
