I camp in the same conditions... I find covering the windows and hanging a
curtain to isolate the front seats is enough for comfort, even below
freezing.. I tnink the dead air behind the interior is pretty good
insulation as is... that glass insulation behind the kitchen is more for
insulating the heat gathered from sunlight against the paint, to help the
dometic work..

Does any one have recommendations on thermal insulation for putting inside
of door panels?  I have removed the interior for body work and rust
removal, which is done.  We have used the camper for nearly 30 years of
camping, so interesting to see that the factory installed fiberglass behind
the kitchen unit did indeed absorb moisture and cause rust. Most of the
rust to be removed was in that location, the lower panel.

Currently installing Fatmat (cheaper on Amazon than GW) for sound
deadening.  Not planning on 100% coverage, more like 40% or so.  Plus I am
not sure this provides much thermal insulation.

We camp in all weather in Oregon, so moisture/cold for sure, and heat in
summer.  Thought installing some thermal insulation would be a benefit, but
after reading several threads on samba I am wondering what to do.

Options:

1) Fiberglass.  I won’t do this given what I found behind kitchen
2) Denim insulation.  I have to assume this will trap even more moisture
than 1!
3) Something like reflectix? But this is more for radiant heat and it may
not have an airspace on both sides.

Other options?

Thanks!
