I have a few small areas in my attic that don't have sufficient insulation. The insulation already in place is blown-in. How practical is it to fluff up blow-in insulation and deposit it by hand in the areas of interest?

A thermal/infrared camera reveals that I have cold areas in the corners where the exterior wall meets the ceiling. So, I'm thinking I could use a garden rake to push the insulation just a bit closer to the soffit to cover that area, but, of course, leave room for air flow.


Yes, you can do exactly what you want to do. If you are using fiberglass, be sure to wear gloves and other protection, and take a shower when you are done.

    …And long sleeves. Fiberglass is awful to work with, and is really irritating to the skin. You don't want to be picking glass fibers out of your flesh for days. I hate the stuff, personally. Go with cellulose if you can, IMHO. – iLikeDirt Feb 27 '14 at 5:21

  • Fiberglass blown in really, really sucks!! Cellulose is so much easier to use as Dirt says. – shirlock homes Feb 27 '14 at 22:08
