How to insulate an existing ceiling / roof with no access?
Hello Experts and thanks in advance for your help. I live in a 1950’s home in San Diego (zone 3B) and many years ago the flat roof (common to military housing of the day) was converted to vaulted ceilings, which are beautiful and spacious, but not at all insulated. I know those of you in colder climates are gasping and asking yourself if this is even legal. There is no attic or even a crawl space above half the house and we really need to insulate it. Every year when it gets cold (yes, it gets cold in San Diego) and our house is 54F and then again in the summer when it gets hot and our house is 93F (we do not have AC and we don’t use our heater), we promise to look into insulating our ceilings.
Is there any way to do this with green materials (not spray foam, but maybe blow in fiberglass?) without ripping out the entire ceiling of our home?
