Insulating paint

Every product I have seen like this their proof (instead of any scientific study) They point the IR at the roof before coating and then again after to show a reduced temperature. Paint any dark roof white and see a significant temperature drop. Take the first temperature during the heat of the day in full sun and the verifying temperature later in the day, under clouds or in the shade for even more impressive results! In the meantime I have 2 parcels of real estate in NY connected by a bridge I would like to sell.


Here is what Wikpedia has to say

So far no manufacturer has provided any independent test results to substantiate any claims of improved performance over standard paint technology. All independent tests have shown that the proprietary formulas offer no advantages at all over plain old acrylic paint. In spite of impressive "web presence" several of these companies appear to be "ghost ships" operating in the cloak of obscurity offered by internet sales and unable to provide any local representation or product stocks
