Photocatalytic shingle that uses sunlight to convert smog into salts that are harmless for us and for the environment.
Acti Roof photocatalytic shingle
The Acti Roof photocatalytic shingles from Tegola Canadese are the perfect solution for producing beautiful, functional roofs with unique qualities:
Convert pollutants into non-toxic salts.
Contain water-repellent granules to help stop soiling substances sitting on the roof.
Have properties that discourage vegetation growth and reduce the number of bacteria and algae that can often form on roofs.
A real “active roof” that reduces air pollution
Our R&D efforts have culminated in “Acti Roof”, actual shingles with a photocatalytic surface that uses sunlight to convert smog into salts that are harmless for humans and for the environment. Acti Roof “smog-eating” shingles exploit the ability of titanium dioxide – an appropriate amount of which is added to the product and activated by the sun’s rays – to react on contact with nitrogen oxide particles (that make up smog), absorb them and subsequently release them in the form of harmless salts, which are then washed off the roof with rainwater in negligible concentrations. Acti-Roof’s photocatalytic effect remains unchanged for the duration of the roof’s life.
