It’s now possible for a roof to reduce harmful, disease-causing pollutants from the air. Boral is the first to introduce this application to roofing products in the American building industry — BoralPure™ Smog Eating Tile. Over one year, 2,000 square feet of the new tiles can destroy approximately the same amount of nitrogen oxide as a car produces from being driven 10,800 miles. (1)
The photocatalyst in BoralPure Smog Eating Tile naturally oxidizes harmful airborne pollutants, helping clean the air. This revolutionary roof tile includes a micro-mortar surface with the key ingredient Titanium Dioxide, a photocatalyst, which is activated by the UV content in daylight. The active surface interacts with harmful nitrogen oxides in the air and helps convert them into calcium nitrates. When it rains, the calcium nitrates are washed off the roof.
