Hi. I'm thinking about another project to keep this old house warm and have seen where some folks have blown cellulose insulation into the walls. We opened one wall last summer while installing a new door. The only insulation in the outside wall is 80 years of cobwebs. As that wall was bead board I took it down and insulated it but that leaves the rest of the house which I beleave is plaster. Or the hardest sheet rock I've ever seen.
I can't find any insulation at the building stores that state that it can be used for blowing into walls it is all for celling use.
Is there a difference? Or is the practice of blowing in walls not safe in some way? IE what about contact with wiring at the switch box ect.
I need to paint the old house on the inside and my daughter is very good at plaster reapair so it would not be that hard to drill the holes and insulate let her repair then repaint.
All advise and tips welcome.
