Alternatives to spray foam insulation

[Bryce C]

I should've already done something, but up until now I figured I was going to shut down my machine. But the idea of not using it for 5+ months is not a happy thing.

Spray foam requires 75 degrees for the foam to properly expand and insulate, and I need that temp with the doors open. So that's out. I'm thinking of using double faced 1.5" to 2" roll insulation and adhering it with 3m spray adhesive 90 cans. Anyone done something similar to this with their vans?

The floor has bed liner on it. But I'll probably lay roll insulation down underneath and around everything near the power pack and plumbing to reduce cold from the floor...

Reflectix bubble insulation is thin and claims a high R value, but part of me feels that something close to 2" thick will do better than some shiny bubble wrap.

Foam insulation really uglies a nice setup. If I were you, I would carpet the floors and walls and possibly the ceiling if you’re good with your adhesive

It would insulate both in temperature AND sound

Carpet tiles on floor and commercial low pile carpet on the walls and ceiling.

Carpet doesn't have great insulating qualities. How about I screw in some brown board/masonite sheets over the tacked up insulation across the walls and roof.

It will be 10 degrees below zero some nights up here...
