Need insulation in 1890 house without tearing out walls
The walls have sawdust in them but it is cost prohibitive to remove it. I don't want to tear up the walls either. Looking for something to fix this. Ideas?

There's a good chance the sawdust has settled to the bottom of the walls. I've seen many old houses where they've had insulation blown in to fill the gaps.
Thank you.
