More advances in green roofing systems
RECENTLY a company has made an addition to the efforts of creating sustainable roofs. Boral Roofing LLC has introduced tile roofing that mitigates air pollution. This type of roof is made of sustainable clay and tile roofing solutions that provide a smog-eating roof technology that significantly reduces nitrogen oxide, which is a key component of smog.
BoralPure Smog-Eating Tile helps with reducing the formation of smog and is installable on both residential and commercial buildings. The technology works via catalysts embedded in each tile that speeds up oxidation when they are exposed to sunlight. Each roof tile contains a micro-mortar surface with a titanium dioxide (TiO2) coating. Through a chemical reaction between the TiO2 coating and nitrogen oxide, the tiles are capable of breaking down dangerous smog particles.
The photocatalytic properties also destroy organic substances, such as dirt and algae, which come in contact with the tiles. Rain then washes off the neutralized substances. In addition to the smog-eating TiO2 coating, the base materials of the tiles are also beneficial to the environment. The concrete tiles are made of locally sourced raw materials, a mixture of sand, water and cement, and they have the inherent energy benefits of high thermal mass, emissivity, reflectivity and an insulating air space between the tile and the deck.
