Solution An innovative noise barrier that removes air pollutants
GRAMM Barrier Systems - Exclusive European Partner for SmogStop
SmogStop 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 byproducts.
And yes, it also blocks traffic noise.
Patented aerodynamic design improves local air quality
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.
Advanced computer models and wind tunnel testing conducted by Western University and the University of Guelph proved that SmogStop can reduce traffic emissions in downwind neighbourhoods by 58 per cent compared to a conventional noise barrier.
Patented photocatalytic technology reduces regional smog
The proprietary coating we’ve developed transforms smog-producing NOX and VOCs into harmless gases and water, powered purely by sunlight. Wind tunnel tests at the University of Ontario Institute of Technology prove that the combination of our aerodynamic design and our photocatalytic coating can reduce NO and NO2 levels up to 37 per cent. Over the course of a year, a single kilometre of SmogStop Barrier can remove 16 tonnes of NOX— the equivalent of taking 200,000 cars off that stretch of road per day.
Meanwhile, laboratory testing at the University of Toronto shows SmogStop is twice as efficient as titanium dioxide at breaking down pollutants.
Clearly the right choice
SmogStop Barrier incorporates CLEARSoundBlok: a sound-reducing, break-resistant and highly transparent grade of acrylic.
The result? A dramatic reduction in noise and air pollution — without sacriﬁcing sunlight.
BOTTOM-LINE BENEFITS: Reducing air pollution saves lives - and money
A single kilometre of roadside SmogStop barrier can create up to £6 million ($10.4m) in benefits each year
