I was up in the attic today trying to clear a quarter of it so I could return the insulation. Even getting past all the junk we are storing there the insulation configuration is odd and of questionable effectiveness. Being the house was built in 1873 it did not originally have insulations. Back in 1945 or so someone decided to insulate the attic and put newspapers on the attic floor between the joist and on the walls on the ends. In the early 1970s my dad had blown in insulation added, somewhat inconsistently I might add. As a result part of the attic just have news paper and some have up to 4 inches which is still pretty thin. Then some squirrels got in around the early 1990s and put tunnels through the insulation. We fixed the area where they were getting in but never tried respreads the insulation. So now I am trying to get enough stuff out of the attic so I can work on at least a quarter of it at a time. I will be doing a full article on it when I get further allow.
