ThermoShield - ein Beitrag zur Wärmedämmung?

ThermoShield – a contribution to thermal insulation?

For some time now, so called thermal coatings are being introduced onto the market. Advertisement to these products announce that these coatings reduce heating energy requirement in buildings considerably. These coatings are facade paintings, e. g the product „ThermoShield“, to which microscopic small ceramic bubbles are added. In the product data to these coatings, a heating energy saving up to 30 % are mentioned. The manufacturer impute these saving to different effects of the „ThermoShield“ coating. To check the upper mentioned promising product properties, the thermal behaviour of test specimens coated with „ThermoShield – Exterieur“ are being studied within the scope of a research work at the University of Hannover. The evaluation of the measurement results showed, that the specimens coated with „ThermoShield“ did not have the thermal properties expected and that this coating do not show any of the promised thermal insulating properties.
