JouleFool was searching for an exterior paint with a high Solar Reflective Index when we stumbled upon Texcote:
On a hot day, the sun can beat down on the walls of your home, and your home can absorb as much as 90% of the radiant energy (or heat)! Even white walls can absorb significant solar radiation. All that heat makes the inside of your home hot and uncomfortable. Running air conditioning to cool your home can be extremely expensive. In fact, a central air conditioning system uses about 3500 watts, or 3.5kWh every hour. In some areas of the country, cooling even a moderate size house requires over 1500 hours of air conditioning operation a year. Now, COOLWALL® – an advanced exterior coating system – tested by the Department of Energy to lower surface temperatures* – can make your home more comfortable while reducing your use of air conditioning.
