Closed cell and open cell aka 2 pound and pound respectively. Loose fill or batt the common term for blanket insulation. The table below shows what levels of insulation are cost effective for different climates and locations in the home. Insulation level are specified by r value.

For diy attic insulation you ve got two choices. Best for attics unfinished walls ceilings floors and attached garages in hot climates. Insulating basement walls or slab foundation can reduce heating costs by10 to 20. You can mix the type and material of insulation too.

Blowing insulation into walls. Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage. Spray foam offers the best attic insulation performance available. Both can be added to uninsulated attics or layered over existing material.
