Study of possibilities of optimalization of properties of alternative thermal insulating materials on natural base
Břicháček, Pavel ; Peterková, Jitka (referee) ; Zach, Jiří (advisor)
The presented work investigates the mechanisms of propagation of heat and moisture in the structure of heat-insulating materials based on natural fibers. The main aim of this work is the experimental verification of theoretical patterns, which are involved in the transport of heat and moisture in fibrous materials, especially the influence of fibers thickness and density of the fibrous materials. To widen outputs of the work were selected different kinds of natural fiber materials of vegetable and animal origin. The results of the work should help to optimize the production processes of natural insulation materials considering their optimal thermal properties. From the data collected are deduced general conclusions to better understanding the behavior of these materials.

Study of reflectance of materials for construction surface treatment
Rauchfussová, Karolína ; Šot, František (referee) ; Šťastník, Stanislav (advisor)
Presented work deals with the study of properties of the progressive heat-reflecting foil thermal insulating materials. The work describes the transport mechanism of thermal energy through the structure of heat-reflecting materials, physical properties are compared with conventional thermal insulating materials. It is also shown here the main applications of these materials are in the field of low-energy and passive houses, especially in terms of the optimal method of incorporating in the building. The practical part is devoted to measuring of reflectance was made and then the measuring device HOT BOX was assembled.

Studying the behavior of cement concrete at high temperatures
Sovová, Kateřina ; Sitek,, Libor (referee) ; Bodnárová, Lenka (advisor)
Bachelor thesis is divided in two parts, theoretical and practical. In theoretical part are listed behaviour of cementious concrete at high temperatures and knowledge from particular construction, that was damaged by fire. There is given procedure of diagnostics for collected speciments of fire-damaged construction. In named analysis belong the carbonation depth through phenolphthalein solution and test of compressive strenght according DIN EN 13791 2008-05. In this study are demostrated results of tests, that were made on materials exposed to high temperatures. Result of constructions analysis is evaluation of economical reapairing works for safety. Practical part deals with measuring thermal conductivity at standard temperature and at high temperatures.

Study efficiency of modern thermal insulation for buildings
Šot, Petr ; auditor, Karel Trojan, Brno, energetický (referee) ; Šťastník, Stanislav (advisor)
The bachelor´s thesis deals with the problem of thermoreflect insulation. The small part of thesis focuses on the energy demand of buildings and its problems. Then the greater extent is analysed problems by heat transfer of material. It includes effects arising from the individual methods of heat transfer and defines the level of expression of individual methods of heat transfer in materials. The thesis presents an overview of experimental methods for determining thermal insulating properties of insulators. Then there is shown a selection of the most widespread insulation materials used in today´s construction. It includes the division of insulators in terms of used materials and subsequent classification of the most used materials in these groups. Another part of thesis deals with the thermoreflect isolation. There are mentioned the necessary concepts for the study of thermoreflect thermal insulation, which include the emissivity surface, the coefficient of mutual radiation and translucency of the material. Then there is described the method heat transfer of thermoreflect isolation. On the next there are presented experimental methods of determining thermal insulating properties thermoreflect thermal-insulating material. The thesis also includes a practical part, which contains the measurement results on a small range of samples taken termoreflection insulators. In the end there is mentioned a brief realization of thermoreflection thermal insulation materials in buildings.
