MonierLifetile LLC (Irvine, Calif.), a Boral Roofing company, introduced SMOG-EATING Tile, a concrete-roofing tile reported to mitigate air pollution by reducing the formation of smog.
A coating of titanium dioxide acts as a catalyst in the presence of sunlight, breaking down nitrogen oxide molecules and reducing their impact on the environment, the company says.
Nitrogen oxide (NOx) reacts with sunlight to form photochemical pollution. NOx is generated from combustion and is present in high concentrations in urban areas.
“Working much like a catalytic converter does in a car; SMOG-EATING Tile transforms harmful substances into safe ones, protecting the quality of the air we breathe,” the company says.
The tile can be installed on new residential and commercial buildings and in re-roofing projects, the company says.
In addition, the company reports that The Fraunhofer Institute performed a test that shows how the tile facilitates a decrease in air pollution when exposed to UV light. The UV rays encourage smog reduction by means of a photocatalytic action. (See graph)
MonierLIfetile says the tile was installed on five earth-friendly prototype homes built by KB Homes for the builder’s Alamosa community in West Lancaster, Calif.
