I am a little confused by R value question. So if the question tell you for example: 2” base coating, R value is 0.78, 1 1/2”brick veneer R value is 5.2, 1/2” finish coating is 0.56. What’s the total value? ( sorry I made this question up, I know the wall section doesn’t make sense, lol)
Should I use the R value multiply the thickness? I don’t think I should, but some of the practice question, the right answer is to multiply with the thickness. Isn’t the R value itself is the materials R value not the R value per inch. Right?
Thank you in advance.
