I have a 1941 home with really no insulation in the walls. I have nice cedar shingles and not overly crazy about re-siding the house. What is blown in insulation like today? Is it toxic? Worth doing?

I had a neighbor once that blew insulation into wall cavities. You may not have this issue in a 1941 house (is it drywall or shiplap inside?)--but one problem he had is that if you blow too much insulation in it can push the drywall right off the studs!

I'd think it would be a far better alternative than taking off siding, though! It just leaves a small hole, between each stud space, to patch.

if the walls have some type of insulation in them already then blown in may not fill all the space.the insulator usually drills holes and then uses a wire to check for structure in the way that would prevent the blown in from getting to places in the wall.

and the insulator will just pop out a shingle for each hole making the holes easy to cover up.
