A Picture is Worth...

About 864 words. I mentioned before that shortly after I bought my house I added insulation in the attic; R-42 over the existing R-15. I noticed an improvement immediately but haven't been able to calculate the benefit in an objective fashion, since I did it right after moving in and had no track record with which to compare before and after.

I do have some subjective ways, though. Yesterday morning I snapped a picture that includes my roof and my next-door neighbor's. It's not the best picture, but you can see that the frost on my side (left) is barely melting while his frost is almost entirely gone. The only variable is the amount of insulation in our attics. I wish I could measure it more precisely, but I can say anecdotally, with confidence, insulation works!
