OK, I have to ask this because eventually I will have to insulate the inside
of the coach. I'm I mistaking or did I read that some of you buy that
insulation with air bubbles & aluminum type material on both sides?
On my 1973 the ceiling in the hallway between the closet and bathroom has a
drop down plastic ceiling, looks like the same material the front headliner
is made of, at one time it was stuffed with some type of black foam
insulation, unlike the rest of the coach walls and ceiling. When I pulled
the panel down that insulation had basically turned to sand, the same way
Styrofoam turns if left out in the sun but a lot worst.
If the bubble foam material is being used for insulation, am I to believe
that that bubble wrap plastic is going to hold up and not dry up and crack
in time in an area that is prone to fairly high heat and freezing cold in
the winter?
In my diesel pusher we used this type material when we parked to cover the
windows as a sun shield, it work well but after some time of use it would
start to crack, now I know that the difference is that it was moved a lot
but still I wonder how it would do stuck in a wall or ceiling and for how
long?
Am I missing something?
Wouldn't fiberglass insulation or standard foam insulation work better and
for much longer?
