Environmental sustainability means
foremost avoiding waste of resources and energy. In
architectural paints, modern and innovative pigments can
contribute to this effort. Heat build-up of roofs and facades by
solar radiation leads to the well-known urban island effect,
higher air-conditioning costs and shortened maintenance
intervals due to earlier failure of coatings. Inorganic complex
pigments with the ability to reflect IR radiation, were tested
in architectural coatings systems showing a significant
reduction of heat buildup and less failure of composite thermal
insulation by thermo-mechanical stress. Hence, lower energy
consumption for air-conditioning and enhanced life time of
architectural composite thermal insulation systems truly
contributes to environmental sustainability. |
