Q:Can I use it. In 2x4 stud wall
by|May 6, 2024
1 Answer
Answer This Question

A:  When you compress insulation in a wall cavity, you lose R value. In this case, the stated R value is 21 but when you compress it into a 2X4 wall cavity the R value reduces to approximately an R15. R15 is available at the Home Store stores or you may purchase on homedepot.com, you may also use R13 in a 2X4 wall cavity. NAIMA provides compressed R Value information, please visit: https://insulationinstitute.org/wp-content/uploads/2016/08/Compressed_R_values.pdf

      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.

            1 Answer
            Answer This Question

            A:  R38 12" 16X48 is for standard attic application that are 16" on center. The R38 10.25 15X48 is produced for cathedral ceiling applications. In a cathedral ceiling, you need to have a 1" air gap between the insulation and the roof deck, so you do not experience roof rot.
