If you compress a 6-inch R-19 batt into a 3 1/2-inch cavity, you get about R-14, or 4.0 per inch. This is a much higher R-value per inch, but the total value of R-14 is still substantially less than the R-19 you started with. Even in a 5 1/2-inch wall, the R-19 (which is rated at 6 inches of thickness) gives you only R-18. For the best
