I learned today that this old house has no insulation!  There is nothing in the attic of the main floor, and there appears to be nothing in the walls, either.  I took the trim off the top of the kitchen window, and there appears to be nothing there.

I found Sunny South Insulators at the Home & Garden show this spring.  A guy came out to have a look, and this is what we found – nothing.  So, it will be $8500 to blow in insulation into the ceiling and walls.
