The thesis presents vacuum insulated glazing in comparison to the insulating glass unit filled withudinert gas. It describes the biggest problem of vacuum insulated glazing and presents solution. The firstudpart describes component elements of a vacuum insulated glazing and insulating glass unit. Presentedudare all of the modes of energy transition through the glazing unit. Using various of glazing materials,udwe perform the calculations of construction physical parameters of glazing units in computer programudWINDOW 7.2. With the program we compare coefficient of heat transfer, the transmission of solarudradiation and the transmission of light between vacuum insulated glass and insulation glass unit.udSecond part of the thesis presents the innovative method of flexible edge sealing for vacuum insulatingudglass. Flexible edge was developed in Swiss Federal Institute EMPA as a part of Winsmart projectudwhich was accepted inside the Seventh framework programme or short EP7. Today's vacuum insulatedudglass unit on the market contains rigid edge seal. The temperature differences between the inner andudouter pane causes the problem of differential expansion of the panes, which with a large temperatureuddifferences leads to bending and also breaking vacuum insulated glass unit. Winsmart projectudovercomes these problems by using the flexible edge seal. The thesis contains results of various testsudmade by developing the method and also the problems that we encounter by anodic bonding which isudcrucial to the flexible edge. We made three vacuum insulating glass units containing the innovatingudflexible edge which are presented including with there problems and weaknesses.
