Easy way to install R49 insulation in my attic space.?

Question

Can I just cut it and roll it in my attic space like a blanket? Do I really need to secure it?

If I have to secure it, what do you recommend I use to secure it?

Answer 1

Yes, you can. Don't need to secure it. If there's nothing there now, you should first put down whatever size you need to fill the joists to the top. Then put down unfaced R-30 or 38 perpendicular to the joists, to fully cover everything. Resulting in an attic of insulation where you can't see the joists any more. And yes, you can have blown-in insulation put in the corners or other odd spaces where you regular fiberglass can't really reach, but I don't like it just in case I need to open up the ceiling, I'll get a face full of insulation and a mess to clean up. Also, I've read on sites where they recommend R-49 for an attic, but real-world truth is that it's just too much. If you get to R-40, you'll be fine.

Answer 2

You need not strictly SECURE any that will LAY on the attic "floor". Certainly you shouldn't be stepping between Joists/rafters anyway. Obviously a Staple Gun will work on "BACKED" blankets against walls.

No offense but you probably didn't have to mention the "R" rating; and for my money; in an attic I always have it BLOWN IN.
