I’m looking for options on how to insulate walls in an existing brick house. I know one method involves drilling ~2″ holes to blow in cellulose. Are there any other options as far getting insulation into the wall cavity with a smaller entry point?
(I just finished demolishing the interior wall, insulating, and re-finishing a closet wall where moisture had condensed on the inside closet face and did some damage. I discovered there was no insulation and suspect the rest of the house is the same.)
