We found this auction on the internet that claims

 

“This system covers 1000 sq. ft.and equals R -100 in insulating value.”

 

This is so far the wildest claim wer have ever seen. It contains 20 gallons

of “insulating coating”.

 

As a rule of thumb, it takes about 5 gallons to cover 250 square feet to .007 inch
thickness for most paints. Since this is for 1000 square feet, 20 gallons would
coat the roof to about seven thousands of an inch thickness. At R-100 this would
make a one inch thickness  R fourteen thousand two hundred and eighty five.

 

 

 

 

 

We also got this web page of a radio announcer or 'radio personality'

We think this so called profession is all about hoaxes, false claims and absurdity journalism.

This link became broken and is no longer available. It was pretty bad. The prize for most absurd in all history however must go to: BUCKMINSTER FULLER for: Not realizing that dome shaped surfaces are extremely sensitive to thermal diffusivity factors. Many people tried building geodesic domes out of plywood and other common construction materials. These are doomed to failure. Why? Because the surface acts like a wet piece of wood in the sun. Technically the heated side begins to conduct heat at a faster rate than the unheated inside. The faster the transfer of energy, the more force that wants to travel in a straight line. The more force going in straight lines, the more flat that surface becomes. Hence attempts to mend the problem usually made things worse and or warped themselves. A wet piece of wood bends upward towards the sun. This is due to evaporation of the water from the surface and shrinkage. You might think because it is hotter on the sun side it would expand, and therefore would warp the other way. However, radiation bouncing off counteracts this and also the tendency for heat to make the surface flat again. All these effects combine to make a very efficient warp drive, so to speak. But fuller never held the hands of his students at all, treating them like sweat hogs. He refered to himself as a guiney pig at times, meanwile most home builders saw him as just a pig. We think he could have spent a little more time in the science and math books and a little less time with his science fiction style exhortation and prophecys, religion and the arts to help out those who may have bought into his design ideas. Ideas about efficiency are never a good unless coupled with another good. Just and idea, just efficiency or JUST information and education are all a big farce and a fantasy. But thats just us, - or did you read the about us section yet?

 

All the internet web pages we found that give information on microsphere paint

additives gave thermal conductance factors that indicate they have no insulation

value that is special at all. Several million dollars are sold each year since 1996 based

on absurd claims. Mainly in Florida and very hot states with NASA publicity.

Glass Microspheres

A. Conductivity: 0.4 to 1.4 (Btu x in.) / (hr. x ft.² x °F) at 32°F (0°C) based on theoretical calculations. Conductivity increases with temperature and product density. The
