Common bar windows are characterised by severe thermal bridge effects compared to the center heat loss of the glazing due to the bars. The solution under investigation has an external bar system glued to the glazing surfaces and an internal bar system kept at a certain distance from the internal glass surfaces og the glazing. In this way the thermal bridge effect is reduced due to the gas filled gap between glass surface and the internal bar. An important question is the level of convection in the gap, which cannot be simulated by common thermal simulation programmes. Therefore, measurements in a guarded hotbox are carried out.
