Hydrated Lime as a Highly Reflective Roof Coating for Home Cooling

Wolfgang provides another example of successfully using hydrated lime as a highly reflective roof covering to pull down attic temperatures, make the house more comfortable, and reduce air conditioning costs.

He provides quite a bit of detail on 1) how he arrived at hydrated lime as the coating to use, 2) applying the lime to the roof, and 3) quite a bit of actual performance data on how much the attic temperature dropped and on AC savings. The numbers are impressive.
