The most revolutionary and regenerative aspect is the membranes ability to decompose airborne pollutants into non-toxic by-products when combined with sunlight (UV radiation). The mineral finish of Nuraply 3PM Pure White is coated with a special type of titanium dioxide (TiO2). When exposed to UV rays, the membrane acts as a catalyst and converts nitrogen oxides and sulphur oxides (NOx and SOx), into harmless and environmentally-neutral substances which are literally washed away by rainfall. These by-products have no measurable impact on the quality of run-off water.
During the process the TiO2 coating is not degraded, instead the decomposition reaction is catalytic. Therefore, the air purifying action is effective for the life of the Nuraply 3PM Pure White granule-surfaced membrane.
Nitrous oxides (NOx) are irritating pollutants which are harmful to health, contribute to the formation of low-level ozone, and increase the greenhouse effect. Nitrogen dioxide (NO2) is a major air pollutant in New Zealand urban areas and National Environmental Standards for Air Quality are regularly exceeded along busy roadsides.
Because of the unique technology, every year, 1,000 square meters of Nuraply 3PM Pure White membrane will offset over 200kg of nitrogen oxide pollution (NOx); equivalent to that produced by approximately 100 vehicles.
Want the best system possible: combine Nuraply 3PM Pure White with a Nuratherm Warm roof for a total roofing system that lowers energy use and eliminates harmful pollutants.
