    Using GreenFiber cellulose insulation in our build was a disaster.
    Dirty, dusty particulates get everywhere and is impossible to control. It gets in your lungs, eyes, skin. Everywhere. This post-consumer waste product traps moisture which likely is why they put BORIC ACID (Poison) in it to control mold spores. We removed it and it was painful. The walls were still wet and they were open on one side. When walls are enclosed it makes a perfect setting for mold and rats. Oh wait… there’s another reason for the boric acid. I’ve had respiratory problems ever since it went in. #Greenfiberinsulationneveragain

    I have to insulate my attic over the existing and very old blown in fiberglass. I am reeling from the various “facts” of cellulose vs. fiberglass. Which is the best? Is there really a fire hazard from cellulose?

    If the exterior isn’t brick, you can use a hole saw to remove plugs in the siding into each stud cavity, blow insulation in, and caulk the plugs back in place. This option usually works best when you plan to cover over the existing siding with vinyl or some other material to hide the plugs.

    Older home built in 1972, walls need to be insullated. I don’t want to tear down the sheetrock, as there isn’t anything wrong with it. Suggestions? Jan
