Either one
by Martin Holladay, GBA Advisor

Ryan,
1. Either product will work. If it were my own house, I'd choose cellulose.

2. Remember, more insulation is better than less. As long as you're installing more insulation, you might as well install as much as you can afford.

I need some help on insulation
by Ryan O'Dell

I built my house 4 years ago and used fiberglass blown-in insulation in the attic. I went up and found that the fiberglass has settled down about 4 in., so i am going to get more insulation to blow in. But do I use more fiberglass or do I get some cellulose and blow it on top of the old fiberglass ?
