GRAMM SmogStop - the world's first approved air quality barrier - reduces air and noise pollution levels in surrounding neighbourhoods, and takes a two-pronged approach to reducing air pollution from major roads, highways and railways.
The patented aerodynamic design reduces pollution levels by enhancing dispersion so that neighbouring residents can breathe easier. At the same time, a proprietary coating on the barrier actually breaks down the NOX and VOCs that produce smog, transforming them into harmless by-products.
GRAMM SmogStop barrier’s angled baffle and double-walled design serve two main purposes.
First, they direct traffic emissions between the two walls, where a photocatalytic coating treats the pollutants.
Second, they generate vortexes and enhance vertical mixing of emissions with clean air, further decreasing pollution levels in surrounding neighbourhoods.
The proprietary coating developed by Gramm Barrier Systems transforms smog-producing NOX and VOCs into harmless gases and water, powered purely by sunlight.
GRAMM SmogStop barrier incorporates ClearSoundBlok, a sound-reducing, break-resistant and highly transparent grade of acrylic.
Result
A dramatic reduction in noise and air pollution - without sacrificing sunlight.
Over the course of a year, a single kilometre of GRAMM SmogStop barrier can remove 16 tonnes of NOX - the equivalent of taking 200,000 cars off that stretch of road.
Bottom line benefits
Reducing air pollution saves lives - and money.
