Barrandov Wall - Five Years An EXHAUST KILLER
|It's not an exaggeration. Not only has this wall been kept clean for 5 years, it can clean air from exhaust gases and other toxic substances in the air.
The wall is coated with a special protective coating FN®Nano, Which Provides a self-cleaning properties and long-term protection against darkening Caused by dirt particles deposited in the air.The coating effectively prevents long-term growth of algae and mold and at the same time fulfills the environmental function - it cleans the surrounding air from dangerous substances and improves the environment.
The noise barrier is next to a very busy roadway, where approximately 30 thousand cars pass by daily. Dirt can build up on walls like this making them appear dark and soiled. And to prove that, the wall surface that is not treated with a protective coating is obvious. After just a few months, the color difference between the FN®-coated and the non-treated surface was clearly visible. Intentionally untreated areas (in the form of squares and vertical stripes in the photo) indicate a level of soiling today after several years.
