Advice on wall insulation
Hi all,
I am in need of some advice regarding diy wall insulation for my currently uninsulated house. The situation is like this: The house is 80y/o, wooden frame, stucco siding. My main concerns are minimizing wall damage, and minimizing fire-spread risk.
For these reasons, I had wanted to go with blown-in mineral wool, but the olny 2 brands I could find (Rockwool and ThermaFibre) have discontinued their blown insulation. I’ve heard about using perlite for insulation, but it seems that it’s a bad idea for drywall due to how loose the grains are (drill a hole, lose your insulation), and the only advice for binding it is to use concrete, which is probably way too heavy (and permanent) for use inside drywall. I also can’t add insulation externally because of the stucco siding.
I’m really at a loss here. I feel like my requirements aren’t so unusual that there isn’t already some product or technique out there to cover my use case, but I can’t find anything still in production. If anybody has any ideas whatsoever, I’d love to hear them.
UPDATE: I did start looking into the sheeps wool recommendations, HOWEVER, in that time I found scrap mineral wool available from ATS that I’ll be able to use as loose fill. Thanks for trying to help, everyone!
