Hi. I'm kind of new to doing insulation on my own. I own a home that is over 100 years old and is made of brick. As far as I can tell there is only 1 layer of brick, a space and then the interior studs making up the walls.

I have been planning on adding insulation myself and until the other day I had planned on adding fiberglass rolls in between the studs.

What would anyone else suggest I do for insulation in southern PA (where we have all four seasons, but no extreme temp changes.)

Thanks for your suggestions
