Thermodynamic Properties of Reflective Coatings

Abstract

As a part of introducing new technologies and materials, reflective coatings are among many other materials ones, which have to be taken into account. This article presents the results of a comparative nature aiming to investigate the thermodynamic properties of selected reflective coatings on energy balance for periods of heating. In order to investigate their thermal performance at the external building surfaces dynamic outdoor testing was used. Two comparative coatings and reference standard facing coating were used for various samples. The measured data demonstrates that the representative coating consisting of hollow ceramic microspheres have the same thermodynamic properties as a standard facing coating, while the reflective coating have distinctive thermal performance effect depending on thermal insulation functions of measured samples.
