This is why we insulate

A few days ago it snowed. It hasn't risen much above 32F since then.

This side of the bus is facing due North. What you are looking at is the result of the sun shining on the other side, warming the interior. That heat has transmitted straight through the ribs and melted the snow.

That's what happens to your precious heat if you don't break the thermal bridge, and in summer it is why your ceiling gets hot and your AC struggles

Not there yet.

That's the factory set-up and it's in very good condition ... so, it really never was all that good

I've insulated, but I still get definite snow or frost melt where the ribs are. A lot of that melting in an uninsulated bus is because of the sun warming the metal in combination with the greenhouse effect from the windows.

My roof looks very similar on most cold mornings. You will see signs of heat loss regardless, but interior temperatures are much different after insulation.

Man just put some magic "nasa" beads in some roofing paint and you'll be all fixed up!

No roof insulating for me on my 20 year old metal tent. I like the stock look and despised the work involved never mind the mess involved. Wanted the bus useable asap so can put up with some heat loss by throwing another log on the fire. Summer, I look for some shade for the afternoon sun and only drive thru the night when cooler.
I'd never live long enough to make that insulting work out for me and when this bus is done, it becomes a parked hunting and fishing camp.
All up to the individual depending on your preferred climate.
I never expected to have the warmth of home or sustained cooling when hot but it ain't too bad.

Well it's getting that anyway. Do you think NASA will let me have some of the tiles from the Space Shuttle too?

There may be a period when we have to spend an extended time in this thing. We are considering building a Container home at some point.

I'll post a pic of HF with her snowcap still intact without the heat transfer at the ribs. Spray foam is AMAZING stuff!!!!!
