Heat Flow Through West-facing Window

Here we can see the effects of direct sunlight on a west window with an aluminum window frame. While some of the coloration on the actual glass is due to reflection, the heat transfer through the window frame is clearly evident by the white spots on the window frame. Note that the upper portion of the window is shaded by the overhang and is not nearly as hot as the lower portion.

The temperature range is from 77°F (darkest colors) to 83°F (lightest colors).
