The Value of R

I finally decided to insulate my crawlspace under the sunroom. This is something I've been putting off for a long time, but the 20 degree temperatures lately are forcing me to do the job. I've taken the temperature of the floor before adding insulation- the ambient temp of the house was 63, and outside temp was 31. This left my floor at around 51-52 degrees. After cmopleting the job, Ive found the floor to be around 59- a 7-8 degree difference!! Enjoy the Pics!


The crawlspace before- there was very little insulation. most of it had fallen down.


This is with the new insulation- R30!
