I live in a 100 year old house that needs insulation. I know I need to be very careful and not get something that can mold or settle. I'm at a loss on what I can use. I know there is some kind of new spray that poofs up alot and is light and air tight. Anyone know about this? What else can I use?

The spray foam is really, really good, altho expensive. Fiberglass or celulose blown in the attic is best. The celulose can also be blown into the walls without having to tear them out. Hope that helps.

Are you sure it has no insulation? Typically older houses used an air gap. If the cinderblocks have a gap between the outer brick, then indeed there is a form of insulation, albeit a fairly ineffective one.

do you have a Home Depot or a Lowes store near you? Home Depot will rent you a machine to blow the insulation in. They might let you use it for free if you buy enough insulation. The one near me does. Ask there people there about what to use , most of the time they have someone who is quite knowledgeable.

It is just called "blown-in" insulation. I'm not sure of the R value, but I understand it is better than traditional fiberglass insulation. We use it in the homes we build, which are in the mountains where it gets very cold.

Expanding polyurethane is VERY expensive to have installed. (for walls)

Blown insulation works well in attics. (somewhat affordable)
