Chris, I know- it's just SO bizarre!! The guy believed in Emperor Pritchetts (and his own) line of BS so strongly that he browbeats the inspector into accepting it as R40 for an R value, then sues the HVAC contractor when the systems can't keep up!?!
SuperTherm is an acceptable "cool roof" coating, but not an exceptional one. It's 3 year solar reflectivity & IR emissivity numbers are somewhat better than cheap white latex, but still scores sub-100 for an SRI at standard ASTM E 1980 conditions. (Way better than most composite shingles, but there are probably better values in the mop-on-coating world.) In no way is it "insulation". |

SUPER THERM is a water-based pain. It was built to meet the needs of industrial users which required a tough surface not found in any flexible coating in the market today, and provide flexibility for the stresses of contraction and expansion. |

Greetings,
I'm sorry to have to correct you but your comments about conduct and reflectivity are way off the mark.
You cannot have have conductivity until you have absorption of radiant energy. Radiant energy IS ALWAYS THE PRIMARY mode of energy transfer unless another factor enters in.
Even on the shaded side of a house will affected by RE because of objects exposed to sunlight and then radiating to the cooler house.
I posted an article I wrote about the "R" value scam on the forum section where they are talking about super(?) insulated roofs.
QUOTE: But on steel cargo can completely shaded under the roof of an open frame
shed the effect is not very much at all- it might be measurable with
sensitive instrumentation, but it won't be measurable in the cooling
bill (or comfort level on a 95F day.)
Not necessarily so. You would have to have a rather tall roof structure that has a good ridge vent system. The RE would be absorbed by steel and re-radiated into the box. If you sprayed a ceramic paint to the under sheathing, or the sheathing had a foil laminated to the exposed side, then you would get the results you are referring to.
