You want spring and push, not static foam just sitting in there, and if you have too much spring behind it, it will over time budge and release off the studs and noggins.

I'm pretty excited about my new room i'm building
It would be pretty shabby construction if the screwed in dry wall were pushed away from the studs by too much insolation. If I were to do a room from scratch, 2x6, I would shoot liquid foam insolation into my walls and fill every nook and cranny! They even have different liquid foam for a variety of applications. Sound proof and the likes. I used it for panels for my walk-in cooler. When I do my frontal lobotomy's you can't even hear the screams! |
You obviously have never put up Gyprock (Drywall) in your life. It’s not that the screws or nails pull from out from the wooden or steel stud and noggin framework. It’s that the head of the screw pulls though the Gyprock (drywall) it’s self when under too much pressure, especially on high humidity days as the outer paper coating softens, it’s just made from paper and powered gypsum, and has no strength itself. https://s3.amazonaws.com/finehomebuilding.s3.tauntoncloud.com/app/uploads/2020/04/24125114/END-VIEW-... If I were to do a room from scratch, 2x6Do that and you may have to re-do the whole lot sooner than you think, this time with 2 x 4" R4 batts in the 4" sometimes 3" wide cavities. I would shoot liquid foam insolation into my walls and fill every nook and cranny!The batts fill every nook and cranny also, and has resistive push against the back of the drywall, foam does not it just sits there, with no resistive spring/push behind it.
