Windows are essential components of buildings providing view, day-lighting, ventilation and solar gain. However, the condensation risk for windows during winter is high due to their higher U-values compared to other opaque components of building envelope. In particular, triple glazing window systems such as Tilt & Turn windows are more vulnerable to heat transfer than the four-track sliding window systems, because of the thinner overall air cavity width from interior to exterior. Having disadvantage of the thinner overall air cavity width within the window glazing, the triple glazing window systems usually applied with multiple low-emittance coatings in order to improve the thermal performance of windows. Radiative heat transfer between glass surfaces can be reduced by applying low-emittance coatings. In this study, the influence of single- or multiple- layers of low-emittance coating location on triple glazing window systems was evaluated to compare the condensation risk of each case by using three dimensional steady state simulation. |
