[QUOTE="-Pjackso, post: 4093822, member: 8119"] Due to the interior air temp being so low, and the heat-loss through the window (read: Window U-value / R-value) - the surface of outside window pane temperature is below the dew-point of the outside air. Hence, With cold windows and High humidity - the condensation occurs. You can control 2 of the 3 variables: -Interior air temperature -Window U-value (R value) -Outside air temperature & humidity (dew temp) Better windows will reduce heat-loss and the outside window surface won't be as cold. (Less chance of condensation) Raising the interior air temperature will reduce the temperature delta, and the outside window surface won't be as cold. (Less chance of condensation) Note: Wall Insulation is measured in "R" values. Windows are measured in "U" values. The 2 measurements are corelated, with U being the inverse of R. U = 1/R, or R = 1/U h t t p s://duckduckgo.com/difference between R and U value [/QUOTE]
