I am going to do this in several steps and try to be as scientific as possible. Suggestions to make it more accurate would help.

Step 1. Measure inside and outside temperature in the garage over three or four days with about 4 readings a day. Looking for the difference between the two.

Step 2. Insulate the garage door and retake the temperature as above. Record any improvement in the difference.

Step 3. Insulate over the garage and retake readings.

Step 4. Add a solar attic fan above the garage and again take readings.

Step 5. Only if still needed, add a garage screen door and check again.

This process will take at least several months to complete, but in the end I should know the impact of each change.
