Heat-protective qualities of building structures are determined by the qualities of the used materials, adequate design solutions and construction and installation work of high quality. This rule refers both to the structures made of materials similar in their structure and nature and mixed, combined by a construction system. The necessity to ecaluate thermal conductivity is important for a product and for a construction. Methods for evaluating the thermal protection of walls are based on the methods of calculation, on full-scale tests in a laboratory or on objects. At the same time there is a reason to believe that even deep and detailed calculation may cause deviation of the values from real data. Using finite difference method can improve accuracy of the results, but it doesn’t solve all problems. The article discusses new approaches to evaluating thermal insulation properties of walls. The authors propose technique of accurate measurement of thermal insulation properties in single blocks and fragments of walls and structures.

Hollow filling by brick mortar may take place in engineering structures with hollow tiles, which leads to thermal properties worsening of a construction. One of solutions to the problem of increasing energy efficiency of enveloping structures is the development of heat insulation material based on cenospheres with increased strength and decreased thermal conductivity in case of operational watering. Homogeneous construction systems based on cellular concrete and porous ceramics meet the structural requirements and also provide required thermal performance. In order to improve operational characteristics of enclosing structures it is possible to apply ceramic materials with effective high porous filler. Manufacturing technology of materials based on high porous filler and clay does not require significant capital expenditures to upgrade existing facilities and it’s similar to technology of ceramic wall materials.
