SOPREMA ECO3 granule-surfaced membrane for low-slope commercial roofing incorporates 3M smog-reducing granules. These granules are designed with a photo catalytic coating that is activated by the sun’s UV rays. As sunlight hits the surface of the membrane containing the smog-reducing granules, radicals are generated that transform the nitrogen oxide (NOx) gases in smog into a plant-usable form of nitrogen that washes away with dew or rain. Reducing NOx pollution can help reduce ground-level ozone. Available in the ELASTOPHENE and SOPRALENE SBS-modified bitumen cap ply product lines.
