**How much insulation can there be?**

**Correction Factor?**

The yellow outline denotes the area of this analysis regarding a “correction factor” that is rarely addressed in the often referred to wood frame R-Value. There are two distinct R-Value classifications: “whole wall” and “center-of-cavity”. The two yield significantly different values.

Wall 1 is 12’0″ wide x 10’0″ high. **31% of the net insulated wall area is wood** not insulation. See table below for specific calculations.

Wall 2 is 28’0″ wide x 10’0″ high. **28% of the net insulated wall area is wood** not insulation. See table below for specific calculations.
