Abstract (en)
[origin: WO2004018794A1] The invention concerns a cleaning system for surfaces exposed to poor weather conditions, in particular roof surfaces, solar heating systems or glass roofs. Said system comprises a plurality of reactive surfaces containing copper which produce, under the effect of natural moisture, compounds having a cleaning action, preferably of substances which eliminate bacteria, algae, fungi and/or lichens or at least stop their growth and/or eliminate pollutants derived from the environment. The invention is characterized in that the reactive surfaces are made of pure copper.
