Traffic Film Resistance

Our inner city building facades are increasingly becoming choked with pollutants from the traffic driving by below. Combustion engine driven; Cars, Vans, Trucks and Busses all spew out CO2 which combines with other contaminants in the air to form smog, which in turn, lands on our buildings and is absorbed by porous substrates such as brick concrete and stone.
