Highest r value insulation.
The best space to insulate in a basement or crawlspace is the walls. This will reduce the loss of heat through the home’s foundation. The R-value recommendation can range from R-25 in warm to moderate areas to R-49 in very cold climates. A range of R-25 to R-38 is appropriate for most of the country.
A 2x4 wall cavity can be insulated from R-13 to roughly R-25. A 2x6 wall can be insulated from R-19 to R-39. Material selection, density, and cavity depth all play a role in the “cavity” R-value of a wall. For the purpose of our discussion, we’ll use R-15 for a 2x4 wall, and R-21 for a 2x6 wall.Cellulose insulation has an average thermal value of R-3.7, so you’d need just over five inches to equal an R-19 batt. A bag of cellulose will cover 36.7 square feet at a thermal value of R-19.Consider using high-density R-30 batts, which are as thick as R-25 batts, but fit into 2x10 framing. You can also add rigid foam insulation under the rafters, which adds R-value and eliminates thermal bridging through wood rafters.
