Bare or covered cabin walls?

[Sailorman Ed]

I am about to start on my aft cabin ref its. Currently is painted FG and we get lots of condensation in cold weather. About to replace the cracked and leaking Windows as well. Wife says no carpet, afraid of mold. Lots of contoured surfaces so anything rigid is out. I was thinking that carpet would add some insulation value. The walls get really hot in the summer sun. The salon walls and Bimini are 1" balsa-great insulation but would be far too much work for curved surfaces.

Thin cork? Fully synthetic outdoor carpet? Another suggestion?
