EcoLogic epitomises forward-thinking and innovation: manufactured using roughly 50% recycled materials as a part of Marley's sustainable building solutions and improving air quality by absorbing harmful atmospheric pollutants (NOx)
EcoLogic has a unique granule finish, using surface layers of granule and cement slurry coatings combined with titanium dioxide (Ti02). This coating works as a photocatalyst stimulated by sunlight to remove both forms of nitrogen oxide (NOx) that form nitrogen dioxide (NO) and nitric oxide (NO2)These can cause respiratory problems and contribute to smog in built-up areas.
The NOx reacts with the TiO2 and sunlight to produce nitrates which are harmlessly washed from the surface of the tile by rain.
Based on the popular Ludlow Major profile, EcoLogic can achieve an A+ rating in the BRE Green Guide to Specification. In addition, compliance with the BES 6001 framework standard for Responsible Sourcing means that projects using EcoLogic can achieve extra credits under the BREEAM family of environmental assessment schemes.
