[It's Hot There]

Looking for before and after insulation results. Just with door insulation we found a 12 degree difference from June before door insulation and June after. Keeping temperature for those months was pretty consistent. Other months temperatures were too far apart for accurate comparison.

Our garage is 20° + less early morning (5-7a) than 10pm temp. Above garage is only builder insulation.
We are considering adding insulation in garage roof rafters, but haven’t noticed any newer facts.

Before and after results are pretty much impossible because duplicating conditions is impossible. Duplicating inside/outside temp, rising temp rate, clouds, etc.
