Heat Protection Properties of Coverings on the Basis of Dry Building Mixes of a New Generation

Reducing the energy resources consumption, including for buildings with a significant time of operation means, first of all, the arrangement of the efficient heat protection of external enclosings. Modern methods for heat insulation of building structures characterized by industrial technology of erection often can’t be used, when conducting capital repairs, for architectural monuments especially. In these cases, the suitable way for improving the energy efficiency of buildings is faсade plastering with compositions of a new generation. The wide choice of dry building mixes on the basis of heat protection fillers presented at the Russian market makes it possible, without changing the exterior finish of buildings under reconstruction to execute the protection of external walls not only from negative effects of weather factors but also from excessive losses of heat in the cold period of the year and overheating in the summer period. The analysis of characteristics of the used energy saving fillers and plasters on their base shows that the compositions which include the granulated foam glass have the best heat insulation properties. The obtained dependence of the heat conductivity factor on the density of the plaster layer makes it possible to assess preliminary the energy saving properties of new mixes when varying quantitative ratios of the components used and their qualities. Possible trends in the creation of plaster coatings with unique properties, appropriate indicators of heat protection and strength characteristics are forecasted.
