Abstract

The thermal performance of a complex multimaterial frame consisting of an exoskeleton framework and cavities
filled with insulant materials enclosing an evacuated glazing was simulated using a two-dimensional finite element
model and the results were validated experimentally using a guarded hot box calorimeter. The analysed 0.5 m by
0.5 m evacuated glazing consisted of two low-emittance film coated glass panes supported by an array of 0.32 mm diameter
pillars spaced 25 mm apart, contiguously sealed by a 10 mm wide metal edge seal. Thermal performance of windows
employing evacuated glazing set in various complex multimaterial frames were analysed in detail. Very good
agreement was found between simulations and experimental measurements of surface temperatures of the evacuated
glazing window system. The heat loss from a window with an evacuated glazing and a complex multimaterial frame
is about 80% of that for a window comprised of an evacuated glazing set in a single material solid frame.
