    Solar roof coverings- passive heat?

    I dare not argue with physics, Stern. I think if we're taking radiative cooling of black surfaces into consideration, we also should consider convection. Having an extra layer of anything at night, black, white, blue, purple, pink, would add some isolation from convective cooling. At any rate...

    Solar roof coverings- passive heat?

    I don't see removing every night as a benefit. If it's a thick vinyl/canvas material, it should almost act as a thin, mostly ineffectual layer of insulation. I don't see how it could cause any heat loss when the sun is down.

    Solar roof coverings- passive heat?

    Thanks for that, Greg. I totally believe those numbers. I love driving a white car for that reason, actually. I argue with my brother in law who prefers the "murdered out" look. (Black paint, dark tint, black interior, black rims) So suppose the roof of the airstream could be 60 degrees instead...

    Solar roof coverings- passive heat?

    That's true, and those are good points. At the same time, new airstreams come with white roofs, and plenty of people paint the the older ones white, so you'd have to think the roof color makes a difference. It shouldn't just go one way, right? The windows would surely also make a difference...

    Solar roof coverings- passive heat?

    Hey everyone- first post here. I love these forums, and they've been an excellent resource, but I had an idea for something and I can't seem to find any posts about it. My wife and I are planning to full time in an airstream in a year or so, and part of this time will be spent in colder than...
