The Use of Thin-Layer Insulation Material in Technical Installations in Building Reconstructions

Abstract:

This article is a part of a scientific work dealing with the research of thermal insulation properties of thin-layer insulation material made of hollow glass-ceramic microspheres in relation to technical equipment of buildings. Until now, there has been a lack of scientific studies describing the effectiveness of thermal insulation properties of thin-layer insulation materials on distribution systems or technical equipment. Thin-layer thermal insulation materials may have a great potential for use in building reconstructions and associated reconstruction of distribution systems, where there is often insufficient space for additional conventional thermal insulation and where energy savings of the whole system need to be addressed. For this reason, a series of laboratory measurements were made and in this particular case, the insulation material was applied in a 2 mm layer to the heat storage tank and the heat losses of two models of the heat storage tank (without insulation and with thin-layer insulation coating) were compared. In addition, for a more comprehensive view of the issue, the two models were compared in two situations that may occur in practice, which are the cases of free and forced convection.
