There are ways to do that, although dense packed cellulose would be far more cost-effective. If budget is not a concern, spray foam is great.
Yes for a 100 percent fact. I seen it done on hgtv.:laughing:Is it possible to spray foam in a finished wall? Say by cutting a hole in the top of the drywall and spraying down? Or do I need to take all the drywall down? Or would another option be better (blown in insulation)?
I have 2 rooms that have crappy old insulation that I can pull out from the basement and wanna re insulate.
