Can you install batt insulation in the cavity of a double stud wall?
Hi, I’m building a cabin in upstate NY and trying to achieve an R-50+ wall. I want build a double stud wall assembly with Roxul Comfortbatt. I’d like to install a continuous layer of batt at the wall cavity (in addition to between the studs themselves). The manufacturer advised against this. They said the batts won’t stay in place unless secured between two studs. I’ve been seeing examples online however, that suggest you can do this. They show double stud wall, cavity filled with dense packed cellulose or batt – unless I’m misunderstanding. Can anyone advise on this? Thanks in advance.
