Energy Savings with TEX•COTE® COOLWALL®
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.
The heat-reflective property of Tex-Cote® reduces exterior wall temperatures by up to 40°F. This, in turn, results in cooler interior temperatures. With cooler interior temperatures, there is less need to run the air conditioner higher, or as often. Reduced air conditioner usage means reduced energy costs because the HVAC system is one of the bigger energy consumers in the home.
Tex-Cote® paint was tested at the Department of Energy’s Oak Ridge Laboratory on a variety of different surfaces ranging from concrete to stucco to wood. In all cases, the researchers found that Tex-Cote® paint reflected more heat than regular paints. This resulted in a reduction in cooling costs of up to 21.9%. This number will vary based on the color of the paint and the climate in which the home is located, but any energy savings provided by Tex-Cote® is certain to be significant.
The heat reflective properties of Tex-Cote® paint also give them superior fade resistance. The fading of colors is called photodegradation and is caused by the absorption of ultraviolet light by chromophores—light absorbing bodies present in colored materials. The UV light breaks down the chemical bonds of chromophores, which causes a bleaching effect that results in faded colors. Reflective surfaces, like those protected by Tex-Cote® paints, are more resistant to this process because they reflect more of the light.
