I was doing some calculations about the net UA for my new home design, and so I needed to calculate the net R value for a wall or roof. Presuming a 1. A 2x4 stud i. So, if I had a nominal R-value of the wall i. Intuitively, it would seem that the net R-value should be about. I wonder if when the energy efficiency organizations say that homeowners should have a certain R-value, that they mean that for the nominal application, or for the net as described. I'm barely going to be able to get a nominal R-value of 19 in a 2x4 wall!

This layered approach enables you to achieve a high total R-value that exceeds the minimum recommended for your climate zone. With some planning and the right materials, you can create walls that are cozy, draft-free, and efficient. The first step in choosing insulation is understanding the recommended R-value for your geographic climate zone.
