The effectiveness of Icopal’s Noxite waterproof roofing membrane in converting nearly 90% of surrounding nitrogen oxides into harmless nitrates has been validated by the BBA (British Board of Agrément).
Icopal says Noxite is ‘proven to reduce air pollution by purifying harmful NOx particles from the air’. With demand growing, a new dark grey finish has also been added.
Noxite can be applied to all roof constructions – flat or sloping. The waterproofing membrane has surface slates/granules coated with titanium dioxide; this functions as a catalyst in changing the NOx particles into ‘harmless levels of nitrates’. The process is activated when UV radiation from the sun hits the titanium dioxide particles, releasing energy for breaking down the particles; the resulting harmless levels of nitrate are then washed away through natural rainfall.
