POLYDAN PRO NOx is a high-performance bituminous membrane that enables a constant reduction of nitrogen oxide (NOx) pollutants in the air, converting them into by-products washed away by rainwater. POLYDAN PRO NOx membranes are manufactured with a photocatalytic coating projected on the mineral granule with a solar reflectance index, SRI= 35. A POLYDAN PRO NOx roof of 1,000m2 neutralises the contamination of 500 cars; when 65% of surfaces in a city are terraces and rooftops, imagine the NOx reduction we could collectively achieve.
