Flat evacuated glazing consists of two plane glass panes separated by a narrow internalrnevacuated space. Separation of the space is maintained by an array of small support pillarsrntypically 0.32mm diameter and 0.12mm high arranged on a regular square grid with an inter-pillarrnseparation of up to 40mm. A detailed three-dimensional finite volume model (FVM) hasrnbeen employed to determine the variation of thermal performance of an evacuated glazing asrna function of glass pane thickness. It was predicted that for evacuated glazing of dimensionsrnof 0.3m by 0.3m and 0.5m by 0.5m, reducing glass pane thickness gave improved thermalrnperformance. For evacuated glazings with dimensions of 1m by 1m, the opposite wasrnpredicted.
