Hi All,

Got the Sound insulation down pretty well,
I'm going to apply 4 coats of Quiet Car.

But, I'm wondering what folks are doing
for Thermal Insulation.

It looks like the Polyurethane foam spray-on Insulation
May be the cats meow

But, what worries me most about it
is Out Gassing.

Does anyone have any info or experience using this spray?
Or can you tell me what you're using?
Not for sound, but for heat/cooling retention/

The main thing I'm getting from the web
Is that you don't want to use anything
that will absorb moisture.

Thanks!
John

Or if you have any info on the
