In Florida and other southern climates we depend on a number of strategies to keep heat out of buildings. Mostly, these affect heat gains by conduction or convection. In the average house, insulating walls and ceilings primarily restricts conduction. Double-glazed windows restrict both conductive and convective heat gain. We have largely ignored radiation - the third means of heat transfer - except in using window treatments and coatings that reflect, absorb or shade from solar energy. But research points to exciting potential for reducing heat gain in buildings by controlling radiation transfer in walls and ceilings through the use of …
