blown-in insulation vs. batts
 

1) If I hire someone to blow in Pink stuff into my attic, will that be
sharp or rounded**?? They might be using the new stuff, but they
might also have taken the old obsolete sharp-containing batts, and
chopped them up to sell like this.

2) Are there any other important differences between blown-in and
batts? For example, I used to see what I thought were pieces of
fiberglass floating around the attic, so I have worn a dust mask
whenever I go up there, but I think most of that has settled or blown
away. Will adding blown-in put more of this stuff in the air than
putting in more batts?

Background: Because It will take me a longt time to get around to
buying and installing more batts, I've been considering having someone
(home depot) blow in insulation for the floor of my attic.

**My current fiberglass is sharp. Before I learned to wear long
sleeve shirts and long pants, I used to feel a bunch of tiny stings
when I got out of the attic. The new stuff they sell, at least the
yellow brand is called "gentle touch" or soemthing and doesn't seem to
have sharp ends. IIRC, the pink Owings-Corning stuff doesn't
emphasize that on the label but it feels the same way.

You should always wear a good mask when fiddling with insulation.

Blown-in I think (?) is cheaper but then if you need to run a wire you
have to fish thru a foot of crap.

Use cellulose blown in.

I agree with Steve. It will reduce air infiltration, fill in any gaps
and work better.

Good advice, about the mask, and the wire.

Previous home owners had cheap stuff blown in, and damaged it by
storing items in the attic. So I suplimented the insulation with
batts on top. I later had to run wires, so it was easy to stack moved
batts into a corner and replace after I was done.

It worked for me.

For air infiltration, I like Icynene. http://www.icynene.com/

Blown in may seal better but settles more, so add 20-25% if you blow in.
I hope you are going for modern R values of 60 or so, not old code.
