HT – breathable air made clean.

The film demonstrates the air-purifying effect:

Activated by light
HT technology works without any further chemical treatment – and therefore without any detriments to human health. When exposed to light, the titanium dioxide in the surface glaze triggers a simple physical reaction referred to as photocatalysis. This process releases activated oxygen on the surface which can significantly decompose industrial and car fumes such as NO_X* from ambient air.

Naturally effective
This unique characteristic makes HT-coated façades an ideal choice for planners and architects when it comes to designing new buildings or modernising the façades of existing ones – particularly in urban environments. An innovative decision of long-term significance for the environment!

Active air cleaning
The photocatalytical process acts like an air freshener here: when pollutant molecules come into contact with the façade surface, titanium dioxide as a light-activated catalyst immediately transforms them into mineral salts which are entirely harmless and which are then simply washed away the next time the tiles are cleaned. This significantly improves the air quality in the vicinity of the building.

*NO_X is an irritant gas which penetrates far into the lungs and can cause damage to the mucous membranes. It is transferred with HT into a water-soluble form which is then washed out of the air by humidity and rain.
