I used to have a friend who had a cellulose blower. That can be a really
great answer to your insullation need. Like the other poster said, it does
mean drilling some holes.

One friend of mine foamed in the door frame around his side door. It
expanded and pushed the frame in so much that the storm door wouldn't close.
ah, well. Can't win?

If by "spray foam" you mean the kind that comes in an aerosol can and
expands to fill a space, or similar items, I think it might be a bad
idea. I am not entirely sure on the details of this, since I have only
seen it used in a few particular places:
- it expands like crazy, and puts a lot of pressure on things that
can't handle it, like drywall, window and door frames (especially
vinyl), etc. It can easily "burst" a wall cavity, or bow a window frame
out of shape.
- it dries to a hard, dense solid, which makes later renovation and
modifications a big pain.

As far as I know, it is best used only in small quantities, for
particular purposes -- like filling up medium-sized gaps in a wall, and
spot-insulation to get rid of drafts.

There are spray insulation products, though, that are meant for entire
walls, like cellulose (fluffed-up newspaper), fiberglass, and other
synthetic products. We did most of our house in cellulose, which
required drilling a few dozen little 1-inch holes in each room to blow
in the insulation.
