Today I measured the temperature in the bath skylight as I mentioned on a early post. Outside temp was 88°, skylight temperature was 128°, yes that is right 128°. The grey tinted tempered glass with the Gila solar film was trapping the generated heat between the skylight dome and the skylight. I could not believe how hot the glass was with only 88° outside temp.
It took me just about a nanosecond to pull the solar film off the grey glass. Now, how is this possible for the temp to be more than the outside temp of 88°.
I used two digital thermometers to measure the temp, both read the same! I guess the reflection of the sun in the closed space of about 3 1/2" works like the magnifying glass with the sun. It just simply concentrates the heat by reflecting the heat from the solar film back against the dome in the trapped space.
I guess I will just have to put up with a little more heat in the shower. The grey tinted glass is warm but not hot to the touch.
A lesson learned
