Re: rim joist insulation in a ballon framed house...

Agreed with Fencepost, however when you have a choice you use the best option.

Back in the day, large multifamily structures here were allowed a between-unit fire-stop wall of 2 layers of 1/2" sheetrock. Being cheaper than masonry that's what most used. After 3 relatively new building burned down completely because these were ineffective the code was changed to masonry or 2 layers of 5/8" sheetrock on non-combustible framing only with mandatory retrofits if that area is ever opened for any reason.

Use the best you can for protection- if you ever need it nothing is ever too good :cool:
