Cooling Paint?

We are converting a BB TC2000 with no AC.

She's already white, but still warmer inside than out.
Any suggestions on an insulating or reflective paint to cool the roof? We mostly camp in the summer months.

How about inside on the ceiling? I'm over 6' tall and the Bird has the handicap raised floor so adding insulation to the ceiling will kill my back.

Lastly, has anyone used Por 15 on their floor?

New to the group thanks for the advise.

I only have the yellow roof to compare with, but We painted the top HALF of our bus with it yesterday and wowwww what a difference. Roof cool to the touch in the South Carolina sun. Also did you pull out your ceiling panels and insulation? If so, I would spray foam flush with the bus ribs after mounting some framing to connect a new ceiling to. Couple pics for reference.

If your roof is already white, there isn't much more paint wise that you can do. Maybe a high gloss white or a chrome?

I'm leery of the "ceramic bead" paints and there usefulness.

As far as insulation goes, most skoolies come normally with thin fiberglass batting. Foam is a better choice but a lot more work.

If you're already white and still battling heat, I'd suggest more ventilation.

There is a member here that did a pretty thorough comparison of various roof coatings.

Hopefully someone can point it out here. As often as this subject comes up, it should be a sticky.

His results showed that making the roof white accounted for the biggest improvement. What kind of coating he use made a little difference but not huge.

The ceramic beads performed slightly better than white paint with sawdust mixed in.....

I'm probably going to go with Henry's because they offer it in more than just white. I want a paint scheme that will hide itself in the woods without being came. Henry's makes a Tan color cool coating I will be using. I doubt the color difference makes any difference in it's cooling performance.

o1marc I am planning a desert sand color for my bus for same reasons, but my roof is already white so I was going to leave it, but now that I see this product, I might do the roof too!

ECCB did the comparative test, (not sure which thread) and his results were that a bright white roof paint was as good, or better than the elastomeric paints. He sampled several paints, on the same material, to get his results.

I have wondered if a white elastomeric paint used on the interior, topped by a bright white exterior paint, would gain any R value. Seems to me that it should.

And I believe that ECCB said that flat white was the way to go. Don't quote me, I could be wrong. It's been a while but that's what I recall.

I thought it was the sawdust that performed the best.
But yeah just making it white is 98% of it. The rest is a bit of smoke and mirrors.

I vote for more ventilation and insulation!

YES! Flat white is the most reflective.
