Vacuum glazing is a vital development in the move to more energy efficient buildings. In vacuum glazing, an evacuated cavity supresses gaseous conduction and convection to provide high thermal resistance. A high vacuum pressure (less than 0.1 Pa) is required and must be maintained by a hermetic seal around the periphery, currently formed with either indium (i.e. low temperature sealing method) or solder glass (i.e. high temperature sealing method). This thesis reports the results of an experimental and theoretical investigation into the development of new low temperature (less than 200°C) and novel high temperature (up to 450°C) glass edge seals. A new low temperature composite edge seal was developed in which double and triple vacuum glazings each of dimensions 300x300mm were fabricated with measured vacuum pressures of 4.6x10-2Pa and 4.8x10-2Pa achieved respectively. A three dimensional finite element model of the fabricated design of composite edge sealed triple vacuum glazing was developed.
