The Noxite® process - from harmful NOx molecules to clean air

Noxite® is one of Icopal’s biggest innovations of the past few years. Noxite® roofing tiles purify harmful NOx.

The surface stone granules of the Decra Noxite® tiles are coated with titanium dioxide which functions as a catalyst in the process of changing the NOx molecules 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 molecules. Polluted air passes over the Decra Noxite tiles where the NOx molecules are converted into harmless levels of water, carbon dioxide and nitrates, which are then washed away by the rain.

As you can see in the video demonstration below, Decra Noxite improves public health, and the environment, as the harmful pollutant is neutralised from the environment
