In a totally enclosed wall cavity, the difference while in the seem attenuation amongst mineral wool and superior density fiberglass batts isn't obvious.
I have under no circumstances found setting up any batt insulation much enjoyable, but considering how tiny time The task requires, I would not make a choice on which type to use based on my consolation.
It absolutely was considered a relatively small priority within just the general air sealing strategy, but recommended as we experienced easy accessibility To achieve this around the whole construction.

You don’t need a vapor barrier when insulating a ceiling concerning conditioned Area in addition to a vented attic.

If that’s the situation, you wish to address the attic side in the wall insulation to circumvent convection currents from lowering your insulation’s success. Occasionally household wrap is made use of, but I prefer to use polyiso. If you use polyiso the exact same thickness as is necessary inside your climate zone (almost certainly R5), Then you certainly don’t will need an interior side vapor barrier.
