David writes again from Louisville, Kentucky: "I have a walk-out basement with 2X6 studs 12 inches on center. Can I use the Pink 2X6 R-19 with Kraft facing and cut it down for the smaller opening? Will the R value be too high for a basement or should I use the R-13 that fits a 2X4?"

Answer: The recommended R-value for a basement is 11. Because you have 2 x 6 studs you can use R-13 or R-19 insulation. Having a higher R-value installed will not hurt. The payback time due to energy savings will be a little longer but you will also be reducing your home's carbon footprint by using less energy to heat and cool your home.
