How to Perform a Home Inspection Class #32

[@kalibbybee4764]

I may have missed it in the few videos I've watched, but is there a conversion chart of how to figure out R-Value? In my area, a ceiling for example has an R-Value of 49. What does this convert to in inches and how to I figure out for other spaces?

Kalib Bybee for batt insulation it’s from 3.5 to 4 per inch.
