Early this year I bought more insulation than I needed (about 13-14 extra rolls)
It's all R-13, 32' length.
Now that I'm using them, they're all flat as a pancake.
Well maybe not that flat, but they're not 3 1/2.
They rolls are about 2", some spots are 2 1/2" thick.
If I throw it in the wall, will it eventually expand to regular thickness?
Or should I fluff it up before I put it in?
Fluffing it will be a mess, time waster, and frankly it's a pain in the rump.
I'm assuming it's just because of how tightly they are rolled, and over time it will fluff to it's normal thickness.
It hasn't been damp or anything like that.
I think I may go ahead and add 1/2" or 1" of foam board in there before I throw the batts in... since it's 3 3/4 to 4" thick walls (not 3 1/2")
humm... $120 to do all the walls with 3/8 board.
EDIT:
Nevermind.
Aside from the fact that the walls are 18" OC and it's a pain to insulate, I'm just going to blow it in.
Put up the first 48" Panel all around the house, blow it in so it's easy to avoid the blocking @ 40".
Then put up the rest and pop a hole and do it that way.
Don't have to worry about not getting it all the way through, or stapling it up, or making sure I properly insulate around the blocking, etc....
