Need some advice on how to insulate my soffit. It is VERY wide (40+ inches at some points, then it narrows down). The inside edge (closest to the wall) of main trunk is still at least 15-16" from the wall. I've framed it with 2x4 (and some ripped down to 2X2). THere is space between the outside edge of the trunk (closest to the room) and between the trunk and the bottom of the soffit.
I've managed to get SOME R19 insualation across the top of the trunk up in the joists, but not ALL joists are insulated this way. in some csaes, takesoffs for upstairs runs are in the way. So, how to insualte?
Here is the Bottom inside of the soffit:
Here is the botom outside of soffit:
Here is the outside sideview of the soffit:
Use the same soft stuff? I have a roll of R13 plus a lot of scraps and I'll have a pretty good aomount of the R13 24" wide stuff left. Solid foam panels? How much to put in the area bewtween the inside of the trunck and the wall...that's where all my wirirng is.
Any ideas on insulating would be greatly appreciated.
