My detached garage was rebuilt in 2015, and 2 of the walls have metal braces with kerfs cut into the studs. The walls are sheathed with tongue and groove. The wall in the picture is 2x4’s 24” on center, with one of the studs sistered. Are these braces structural or were they temporary during the rebuild? I’m in the process of insulating my garage and these braces are keep me from touching thoseb2 wallls. I don’t want to place insulation because the braces will compress it, reducing the r-value. Thanks in advance.
They must stay. They are structural and the small amount of compression in that small space will not affect the performance of the insulation as much as a receptacle or light switch.
After speaking to a licensed contractor, we determined these were temporary during the remodel. These strips are only meant to be in place before siding is added to the exterior.
