“Smog-Eating” Roofing Tiles Convert Pollutants into Nitrogen
MonierLifetile, a Boral Roofing Company, has introduced “smog-eating” concrete roof tiles which they say will reduce the amount of smog in the atmosphere.
According to the company’s product brochure:
- Significantly reduces the effect of smog on the environment. Over one year, a 2000 sq ft smog eating concrete tile roof can destroy the same amount of Nitrogen Oxides as a car produces from being driven 10,800 miles.
- Made purely from minerals with an inorganic surface that withstands weather conditions.
- The tile surface does not promote organic growth such as moss and algae. Airborne pollutants are destroyed by the effect of sunlight on the catalyst and are rinsed off by rainfall. Additionally, because of the special pore structure, the concrete tiles dry out in half the time it takes ordinary tiles.
According to EcoHome via BuilderOnline [link], this technology has been used in Europe for a few years, mainly on road materials. Boral is testing it for other product offerings, including clay tiles.
The tiles will carry a price premium, an increase the company expects to come down with volume and time. Installation, performance, and weight are unchanged.
