Novostavba rodinného domu
Součková, Daniela
This thesis deals with the design of a family house for 4 persons, which is situated on a particular site. The text part of thesis defines problems of sloping roofs. The practical part of the bachelor thesis deals with the evaluation of selected structures these roofs and the possibility of roofing the proposed building. The evaluation is performed in terms of thermal insulating and price. Part of this thesis are separate attachments.
The Influence of Thermal Insulation of a Concrete Panel Block of Flats in Ostrava on the Expenses Related to its Operation

Residential building, thermal insulation, thermal insulation system energy saving, economic return on investment
Study of utility properties thermal-reflective insulations in the buildings
Holeček, Dominik ; Skříček, Darek (referee) ; Šťastník, Stanislav (advisor)
The diploma thesis is partly dedicated to energetic efficiency of buildings and describes possibilities how to evaluate energetic efficiency of buildings in the Czech Republic. We also get to know with distribution of thermal insulators by material base and use in construction. There are also mentioned methods how to determine thermal insulations characteristics of heat insulations, so called heat conductivity coefficient. The last and the crucial chapter of theoretic part is dedicated to thermal-reflective insulations. There are mentioned some of the basic characteristics of insulations, material composition and heat transfer mechanism in their structure as well. Practical part describes measurement of thermal resistance of chosen samples of thermal-reflective insulations per measuring device on the principal of Hot Box method. In the next step was determined emissivity of aluminium foils which forms the surface of chosen samples of thermal-reflective insulations. In the end of thesis are defined possibilities of use thermal-reflective insulations in building structures especially in passive and low-energy buildings in climatic conditions of the Czech Republic.

Kosturová, Andrea ; Třísko, Pavel (referee) ; Zach, Jiří (advisor)
The objective of the presented diploma thesis is to evaluate the influence of modification on surface layer of products with their base structure from organical fibers and on the ability to resist increased humidity. Emphasis is puted on the description of humidity propagation in fiber materials ant he approximation of secondary waste from the textile industry as a potencional material for thermal insulation. The end of the theoretical part focuses on the types of possible surface treatment to prevent the ingress water into the structure of the material. The practical part verifies the selected type of modification of the surface layer of three materials choosen as test ensemble. After applying surface treatment, the effect of treatment on humidity sensitivity and water absorption was assessed. The determination of the thermal conductivity coefficient, the short-term absorption at partial immersion and the determination of the sorption humidity were made.
Analysis of the thermal resistance of insulation systems from foamed insulants in flat roofs
Rundt, Lukáš ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
On many structures there ocurred a problem of expanded polystyrene-based thermal insulation material degradation caused by high temperatures close to glazed areas. In a theoretical part of this Master’s Thesis there are the most common thermal insulation materials described, followed by a brief desciption of flat roof waterproofing materials and a thermal stress of structures. An experimental part describes a design of a methodology for evaluation of thermal resistance properties of foamed insulants in flat roofs and several experiments carried out according to the methodology.

Holeček, Dominik ; Skříček, Darek (referee) ; Šťastník, Stanislav (advisor)
The bachelor thesis is partly dedicated to energetic efficiency of buildings and describes possibilities how to evaluate energetic efficiency of buildings in the Czech republic. There is also detailed description of the heat transfer in buildings. We also get to know with production and characteristics of chosen thermal insulators. There are also mentioned methods how to determine thermal insulations characteristics of heat insulations, so called heat conductivity coefficient. The last and the crucial chapter of theoretic part is dedicated to thermo-reflective insulations. There are mentioned some of the basic characteristics of insulations and its material composition as well as usage and methods of thermo-reflective insulations installation in buildings. Practical part is dedicated to description of chosen samples of thermo-reflective insulations and determination of their heat resistance though Hot Box measuring method.
Study utility properties of heat-reflective insulation for the buildings
Rauchfussová, Karolína ; TROJAN,, Karel (referee) ; Šťastník, Stanislav (advisor)
Presented work deals with the study progressive heat-reflecting foil thermal insulating materials and defines their thermal insulation properties. The work describes a transport mechanism of thermal energy in the structure of heat-reflecting materials, their physical properties, especially heat resistance, compared to the conventional thermal insulating materials available on Czech market. The main applications ways and installation methods of these materials (especially in low-energy and passive buildings) are also shown. The practical part is focused on asembling the measuring device HOT BOX in accordance with the valid standards, to determine the heat resistance of heat-reflecting materials. In next step the measurement of reflection of aluminum foils (an integral part of the structural arrangement heat-reflecting foil insulations) was performed.
Validation options for increasing the thermal insulating properties of foam plastics
Smutný, Vojtěch ; Kopřivík, František (referee) ; Šťastník, Stanislav (advisor)
The thesis is devoted to the study of material properties of selected types of polystyrene, especially expression of the coefficient of linear thermal expansion. The work contains two main chapters, theoretical and practical. The theoretical part of the thesis deals with an overview of the thermal insulation in the Czech Republic, the description of phenomena related to heat transfer mechanisms and an overview of experimental methods for determining thermal insulating properties. The practical part presents results of measurements of samples with foamed polystyrene, which is modified by the addition of selected substances. The thesis describes the machine program, which is used to calculate the temperature in during the construction arrangement under the sunlight load.
