Abstract: Window spacers are weak points in terms of heat loss and condensation, due to relatively high thermal conductivity. For this reason, thermally improved spacers (TIS) are considered as alternatives to mitigate condensation risk and heat loss of the window. However, it is difficult to expect the effect of the TIS on the condensation risk and heat loss, because it is usually composed of very thin foil and adhesive. In this context, simplified simulations using the two-box model were performed to investigate the impact of window spacers on condensation risk and heat loss of the window. For commercially available TISs, temperature factors and total U-value were analyzed with THERM and WINDOW simulation. Based on the results, design charts were suggested to help designers to select a proper window spacer which can mitigate condensation risk and heat loss through the window.
