Abstract—The development of vacuum glazing represents asignificant advancement in the area of low heat loss glazing systemswith the potential to substantially reduce building heating and coolingloads. Vacuum glazing consists of two or more glass paneshermetically sealed together around the edge with a vacuum gapbetween the panes. To avoid the glass panes from collapsing andtouching each other under the influence of atmospheric pressure anarray of support pillars is provided between the glass panes. A highlevel of thermal insulation is achieved by evacuating the spacesbetween the glass panes to a very low pressure which greatly reducesconduction and convection within the space; therefore heat transferthrough this kind of glazing is significantly lower when comparedwith conventional insulating glazing. However, vacuum glazing issubject to inherent stresses due to atmospheric pressure andtemperature differentials which can lead to fracture of the glass panesand failure of the edge seal. A flexible edge seal has been proposed tominimise the impact of these issues. In this paper, vacuum glazingsystem with rigid and flexible edge seals is theoretically studied andtheir advantages and disadvantages are discussed.
