Q:Can I use 2 layers of R13 inside of a 2x6 wall cavity?
by|Apr 16, 2024
1 Answer
Answer This Question

A:  You can use R13 kraft and an R13 unfaced, you cannot install double vapor barrier, meaning two batts with kraft facing. You could encounter condensation in the walls, if you do this. Also, you would be compacting the double layers of R13. Each batt is 3 1/2" thick and the 2X6 cavity is 5 1/2" so you will not achieve a full R26. R19 and R21 are specifically manufactured for a 2X6 application and Home Depot should carry the R19 and/or R21.

          Remains flat even after after a day wait. I wonder if I’m getting the proper R factor rating? Paper is offset to one side making it hard to install.
