Roofing material TECHNONICOL ENVIRO AIR has a positive impact on the reduction of nitrogen oxides NOx in the air. The surface slate of the TECHNONICOL ENVIRO AIR membrane is coated with titanium dioxide TiO2 and special additives, which functions as a catalyst in the process of changing the NOx into harmless levels of nitrates. The process is activated when ultraviolet radiation from the sun hits the titanium dioxide particles, releasing energy for breaking down the NOx particles. Polluted air passes over the TECHNONICOL ENVIRO AIR membrane where the NOx are converted into harmless levels of water, carbon dioxide and nitrates, which are washed away by the rainwater.
